The Campagnolo Question - Team Lotto Belisol Ridley Helium.
Вставка
- Опубліковано 13 бер 2023
- What would you do? Here is an exquisite Ridley Helium SL from the 2013 Lotto Belisol Team. It came right from the Pro Tour and has only been used a handful of times on sunny days since then. It came fitted with Campagnolo Record EPS 11 Speed. Sadly the V1 Battery has failed. It holds charge for about 50 gear changes and then dies. Not ideal. Our solutions:
1. 2nd Hand V1 Battery.
- Pros - Cheapest option, and keeps everything original
- Cons - Unreliable with potential for ongoing labour as its a difficult part to replace
2. Upgrade to V3 Battery
- Pros - Keeps things original and makes use of functional components
- Cons - Expensive investment for old components.
3. Go Mechanical
- Pros - Cheapest and most reliable option
- Cons - End of life for top of the range parts and downgrades the bike
4. Entirely New Groupset
- Pros - Ongoing reliability and part availability
- Cons - Very high cost - Спорт
Remove the battery. Disassemble the battery. Replace the cell/cells. Glue battery back together. There are companies that can do this at least in the Netherlands where I live. Pretty reasonable pricing but it will take time, 1 ~ 3 months as they are a small outfit.
Yeo do this. Surely an easy job for some one with any electronics knowledge .
Is that specific to Di2 EPS batteries or do they repair any cell type ?
Is do the same. Usually these batterys just consist of standard lithium cells that are stacked. But you should watch out to get similar or the same type of cells, that the control and safety chip is satisfied. With some basic electronic and soldering skills that can be done in very little time and just a few bugs.
@@lukasniederl6278 yes, and since we talk 2013 bike, this chip must be easy to satisfy. It may even be so that only one cell is faulty and there is just a problem with balancing.
This provided they dont have any specific anti diy design.
I wanted to do this for my ebike battery. Unfortunately, it's a carerra from Halfords and they deliberately included a feature on the battery management system board which means that it bricks itself if its detects the cells being disconnected -.-
If the battery is basically dead anyway though nothing to lose from giving it a go.
i would absolutely get mechanical 11s. that price is outrageous for repairing old stuff. the whole groupset shouldn't even be worth that much
For this situation I'd disassemble the battery and replace the cells. It's not a difficult process but takes time, and you'll have a significant downtime while you find out what the replacement cells are and source them.
Alternatively you could outsource the work to an electronics repair shop, the guy that has fixed a couple cell phones for me also does laptops and small electronics and has always been super helpful. I'm sure there are electronic repair places that could do it.
I haven’t got anywhere with this yet. The 2 places I tried have refused to even atempt to open it. It is really well sealed.
Option 3 - convert to 11sp mechanical. The bike is 10 years old, there's nothing magic about it.
@John Brown It's a not a steel frame bud, a carbon frame after 10 years is not the same
I would keep the integrity of the bike, keep Campy and upgrade the battery for £650. Not cheap, yes, but that's still a lot cheaper than a new Di2 or AXS groupset. Do what makes your heart happy mate.
I don't consider putting on mechanical a downgrade. I have been riding Ultegra Di2 for the last 10 years in its 3 iterations. 6 months ago I changed to Campagnolo Record 12 speed mechanical and to be honest, it feels like an upgrade. Only the front shifting is inferior to the Di2, but everything else feels better. If this was my bike, I'd defo recommend going to Campagnolo mechanical, be it Record, Chorus or Centuar.
Love the channel btw, keep it going!
Thanks. Centur is the only 11 so option now.
Stay true to the heart of the bike, bite hard a pay for the new battery upgrade… Will be hard going dropping from sweet precision gear changing Or go mechanical, depends on your budget, but keep Campag all day long. Good luck
This is the future of all electronic groupsets! Nothing green anymore. Just more elektronic scrap for no reason. One big winner: The profits of the manufacturer. Go for a mechanical groupset that will last for ages! 🙂
I have exactly this bike and my v1 battery died soon after I had it from Merlin. I replaced TH battery and control unit with v2 in 2015 and I use it as a winter bike in all weathers it’s been absolutely faultless, the key is to make sure you keep the battery charged and when not in use for any period of time make sure you use the battery isolator strap. I have a super record v3 eps on another bike and same with that it’s been brilliant. I’ve got Ultegra Di2 on Cervelo C5 which was my main winter bike I love the ergonomics but in winter the reliability has been patchy. Rear mech packed up and other issues with it so the Ridley is now my main winter bike even though it’s much older.
Outside of sorting battery: Chorus 12 levers and mechs and cassette/chain. Keep rest. Sell other bits. Lets not also forget that you can get into the same mess with 10 speed Shimano electronic (no parts) and anything old in SRAM is unobtainable/lousy second hand option in the UK. This article is describing the future of all electronic groupsets. Fire up soldering iron, do the research and sort the battery is what I would do myself.
I have this exact frame and rode it with Centaur 11. I only upgraded the crankset to a used Record crankset and I used Chorus rim brakes. It rode beautifully. I can really recommend Centaur. It's stellar bang for the buck IMO. If I was looking at this project, I'd probably try and upgrade to the V3 battery and look for a used charger and EPS interface unit.
If you can keep the crank, cassette and brakes you can update the rest to R8050 for about £870, that includes battery and charger. Some really good individual deals on components at the moment.
I'd just eBay some 11 speed Ultrashift shifters/mechs (rather than new Centaur). I'm still running pre-2015 Ultrashift on 2 bikes, and it's as good as new. Plus there's the environmental benefit of buying used, rather than new.
I had a similar problem. My 2014 Argon 18's rear mech and front mech shifter both went around the same time. Problem was they were both Ultegra 6700 which are no longer available. So, I got to doing some research and found out that the R7000 105 will work with the Ultegra 6700 crank and brake callipers. So, I made the rather inexpensive swap and it was like getting a new bike. What I would do is try your best to keep the crank and the brake callipers and replace the shifters and derailleurs with modern stuff. Oftentimes the 11 speed cranks will work with 12 speed groupsets or vice versa, just as 10 speed cranks will work with 11 speed groupsets. Of course it depends on the spacing between the big and small ring plus the width of the front chainrings. I know the Shimano 6700 cranks are almost identical in measurement to the newer 11 speed stuff, maybe the Campagnolo is as well?
Send it to me, I love that generation Helium and it looks my size. I would put a 11 speed Chorus mechanical shifters and derailleurs on it and be very happy.
Good job I am old school , not too fussed about electric shifting……………..and prefer rim brakes (in case I haven’t mentioned that before once or ten times) 😂
Excellent dilemma Paul ! Great vid ,,,,,,,,,,,,,,,,honestly edge of the seat /gripping stuff 👍. My take depends what you want it for, where the owner sees its value, in generic sense. Near period correct preservation V3 route.
For daily riding centaur as you mention or for me a left field choice of chorus 12 speed mech group for equivalent performance to 11 speed EPS. No compromise in shifter inner parts, cassette choice down to 11/34 cf 11-29 and for riders missing the ‘buzz’ sound, always an option to shout ‘buzz’ before mechanical shifting ☺
lol, thanks Kevin
It’s an older bike, I’d go the replacement battery route off eBay and try your luck - even if you have to buy two.
Failing that, I’d go mechanical and sell the EPS which someone else likely needs the parts for and will reduce the overall out of pocket.
This is a perfect example of electronic groupsets stupidity. Anyway, last year I've built my first road bike with rim brakes, (I have a few disc brake bikes, but I wanted something UCI illegal) It's the cheapest canyon ultimate frame with campy gruppo. Centaur shifters are lighter than ultegra and I love thumb buttons. Brake calipers are chorus. But I've found centaur rear derailleur a bit sluggish, I've changed it for potenza RD and it's now perfect. Finally, bike weights 6.4 kg, I'm happy 😊 btw casette is 11sp Dura ace, with m9100 12sp chain.
Have both Campag Record & Chorus 11 Groupsets (mechanical) both flawless
This whole video makes me want to cry
Oh
Replace the battery with the gen-3 battery. It keeps the high end aesthetic and will still look like the original team. It's not cheap, but still cheaper than replacing with a different groupset, and avoids the downgrade to Centaur.
Pop over to Italy, apparently Campag stuff is much more reasonable over there.
You need to find someone who can open that battery carefully and copy/design/3dprint a new case (improved, openable etc), you could sell these later for others in the same situation.
Ask some tech colleges or universities, possibly a 'design' studio (who is the guy that makes titanium bits and bikes, he's been on gcn? Or, MagCad, he's an engineer and cyclist. Someone like that).
You might even be able to scan the case (take loads of pics of it) that could be converted to a 3d file (PolyCam is one I've heard of).
Get a spare to hack open as well.
Swapping the batteries/cells would be a piece of cake, I'm sure.
It's pretty poor that Campag leave customers in this situation. They used to be the ones that helped the cyclists and you could get any part. They could help here with an exchange programme or offer a rebuild kit. It's absurd expecting people to pay to upgrade, especially when they've paid a fortune for the stuff in the first place!
All the best with your efforts!
This shows a huge disadvantage of electronic groupsets that nobody ever mentions. You are basicly locked in and dependent on the vendor for expensive or hard to get spares and possibly software updates. You could maybe replace the battery now, but will you be able to source a new one when it dies again in 5 or 10 years time?
Its not just groupsets. Wait until the dust settles on the ebike "wars". Most of these ebikes have many small, fragile, limited, and proprietary motor components that will simply be unavailable in 10 years. If you're going to buy electronic components, stick to Shimano because they will still be around, and for the most part their stuff just works, even if its a bit boring by comparison. If you're going to buy an ebike, fork out for the Bosch motor.
I agree. That’s one of the things I’ll give SRAM. They’ve used the same batteries over all 2.5 generations of etap. But, as you said, if they ever redo the battery interface, the spares for older ones will dissipate, and you’ll have to either replace the whole group or rely on 3rd party duplicates.
Very true. I have a vid planned about those non branded eBikes. Disaster.
The same looking people 😳
@@byc1013 I'm gonna need you to take it down a peg on that not so covert racism there bud
Depends on what this bike means to the owner. If it’s their only bike, puts tons of miles on it, washed it after every big ride and want to keep it going the same way it did when they purchased it then I think it’s worth the 650 to upgrade the battery. The last battery lasted them about 10 years and if they can get another 10 from the new battery it’ll come out to £65 a year. That being said if the owner has been thinking about another bike then maybe they should save their money, buy mechanical components (used preferably) and ride it till the wheels fall off or turn it into their winter bike.
This is not a solution for the problem, but still interesting.
You are going to love what Archer components are working on.
Smaller shifter, not sure if the motor is smaller, but whole box is smaller and has hot-swappable detachable battery, and will work with Sram AXS and Shimano DI2 batteries, they have a connector that works with both.
Seen this. Path Less Peddled covered it some time ago.
@@nickyburnell He covered the current version a year ago, In a video called Make EVERY Derailleur ELECTRONIC! he showed the TRP specific remote that integrates into the drop bar brake levers from TRP. They also have standalone buttons if you don't have TRP brakes. 2 years he did a video called Should Shimano and SRAM Be Worried?, where he shows the shifter, and the previous remote, which has been replaced by a paddle remote. I have both remotes. I also have the faster red batteries. they make shifting 50% faster.
But I meant the new unreleased product. I mean the new product under development completely new shifter. current version does not have, detachable batter AXS & DI2 battery compatibility.
They posted vids on Instagram.
This is why a key factor in why some of us are not switching to electronically-controlled shifting. Today, for about $50 US, I can buy half a dozen stainless steel Campagnolo shifter cables. That's three changes front and rear, enough to keep outfitting my Potenza 11-speed groupset for the rest of my days on Earth. The same number of cables for my "antique" 9-speed Ultegra and 10-speed Dura-Ace systems cost even less. I can win the battle over planned obsolescence for $50? Yes. Yes I can.
Great comment thank you.
For myself? I would go the #3 Centaur route. Centaur is very good function wise & as an aside has drooped thumb levers like eps which is nice IMHO. Also you retain that nice light crankset.
I love Campy but hate how not everything works together at times.
holy crap , campy really does take everything worst about component lifecycles, modern standards and incompatibilities and turns it up to 11
The other stuff yeah sure but “lifespan” you couldn’t be more wrong campagnolo chainrings, cassette and chains absolutely shit all over SRAM. Shimano pretty much always do a good job…apart from their cranks which was an absolute joke.
Actually they turn it up to 13 now...
@@JulianKent 😄 good one…
@@cpt.slackbladder3187 lifecycle and lifespan are different things , this era of campagnolo is basically obsolete now less than 10 years later, whether their chains are made of magic steel or not
Yeah, I have a 2000s bike with 10-speed Chorus and it seems all you can still get is Veloce, which is a few tiers down. If I ever have a crash and need new STIs and a rear mech, it'll be a long journey on Ebay and spending 500€ on components.
A question that any one with any electronics with proprietary batteries, not just bikes, will have to face when the batteries expire. 😢
Loved my Bianchi with Campagnolo gears but replacing worn components became impossible so slowly moved to 9 speed Shimano compatible parts. Either get used to having to replace groupset/bike every few years or stock up on NOS sale parts and mix and match. Stuff should be repairable but there is too much planned obsolescence in the bike industry.
Either upgrade to a V3 battery or source a new 11 or 12 speed Campy Record mechanical group set. Plenty of NOS 11 speed stock floating around on the internet
Replace the shifters, derailleurs with Centaur 11 and ride it. Or as others have said - tear apart the battery and replace the cells.
I would replace the groupset with Campagnolo Chorus mechanical. Beautiful groupset which suits the bike really well.
This is sad, innit? So to my (probably incorrect) mind, that original battery is a PCB board controller and a pile of Lithium-ion batteries. I'd start searching for someone who can replace the latter without ruining the former. Someone smart with electronics. I'd bet the software on the controller isn't so advanced that it can tell when the battery cells have been replaced, as long as they match capacity and output.
Mechanical centaur would still be really good so would go for that.
I'd bite the bullet and do a battery upgrade for 650. Failing that record mechanical. It may be old but it's a beautiful bike. I have one of the newer disk brake versions and love it, underated bike.
I'd go mechanical and sell the eps stuff. probably the least net cost option. I'm not emotional about the frame so the owner might feel different about the downgrade. If I had the money for option 4, I'd save a bit longer and get a new bike.
I’d go Centaur. Good workman-like kit, sensibly priced…
A bike with pedigree and heritage? Such deserves proper repair. Apologies for the cost, but nothing else fits.
I would upgrade the battery to V3. Eventually I will be in your situation. I have 2015 V2 battery, Campy EPS on my bike.
Is it possible to change only the battery cells? Is it a generic cell unit inside? Someone made the batterys for Campagnolo. Not some DYI job, but someone with eletronics knowledge, might be able to do it
I'd go mechanical. I found almost unethical the price of an electronic groupset, for the price of the new wireless campagnolo you can get a good new bike.
Centaur parts. The bike will still be beautiful to ride.
We did the upgrade to new battery once at the shop. And it gave and error code in the derailleur so we had to change the rear derailleur too
Oh ouch!!!! That’s gotta hurt.
It’s an ex professional team bike with, as you say, heritage and history.
Period correct should be your aim, do not spare any expense to keep it true to original.
Cut the battery case open and look inside. I doubt Campagnolo invented a proprietary battery. They for sure put standard batteries inside. It is interesting to see that nobody has done that before. You could be the first to open a V1 battery on youtube!
💥
@@Mapdec do it!
Check out Keith Wakeham, and maybe reach out to him for advice. He helped to design EPS and has always been super keen on this stuff. Right now he's been posting about his "EPX" project which is specifically to upgrade the battery tech on the EPS system.
Where are his posts ?
@@Mikadobiscuits youtube.com/@kwakeham
@@Mikadobiscuits here on YT, he even posted an update just yesterday
His latest post will also teach that a "battery" sometimes is more than just a "battery". Well spent time. Rgr
Nothing back @keith Wakeham yet.
if it's just a handfull of good weather rides try to keep it original but it depends who bought it and why. an ex pro team bike full campagnolo, how many of those are there floating around? sometimes the most sensible option does not make the most sense
Thinking forward, even if you replace the battery now, how long would it last. I wouldn't want to move away from Campy myself so I'd either have to swallow hard and change to manual Centaur or swallow harder and fork out for the new Record EPS. I'd probably go with Centaur, as the new record EPS is probably too good for that frame.
Thinking forward even further, if you replace with a new EPS or Di2, how long would that battery last and when it dies, will there be a replacement in the future?
Maybe 5 years with campagnolo.
I love Campagnolo... To be honest I don't think I would buy Campagnolo again but in my opinion the Campagnolo 12 or 11 spd mechanical is better than 11 spd eps.
Otherwise everyone else has hit the nail on the head with recommending replacement of the battery cells.
Aye. Despite several attempts I am getting nowhere with that idea.
Interesting video, There must be somewhere/someone that can either refurb the battery or sell a non genuine replacement, hopefully the power of UA-cam can help..
Paul just a thought ……..have you ransacked your washing machine and tried the Obree method ? Lots of shiny electronics in there ……..perhaps it’s the future 😆
😳
I’d either see if it’s feasible to take the battery box apart and replace the battery cells or see what voltage the system needs and build an external home made battery box.
I am exploring this. There is a lot of doubt about not breaking the casing
Not sure 11speed Centaur will work with pre 2015 Record shifters, Centaur is very good but a step down even from pre 2015 Athena. I'd suggest mechanical post 2015 Chorus or Record 11speed but I know how hard they are to find. Record mechanical 12 is lovely, extra ratios, 32 & 34T cassettes, looks great and can be got for 105 Di2 prices.
One question, is there some sort of extender on the fork? I've never seen a pro team bike that wasn't slammed.
Mechanical Centaur so the shifters would be replaced as well.
Yes there is an extender. 😳.
Take a chance on a replacement ebay battery for £65 or whatever it was. If that turns out to be crap, go for some used or nos Chorus or Record 11spd mechs and ergos and enjoy.
I hope you go for the battery cell changing option, don't throw away that groupset yet, however, you Open a new topic too, what happen when our old di2 campy o sram get obsolete, and this is on a bike from 2013, i got a synapse from 2017 and i just hit by the same problem too expensive options , like the latest or the r8050 or red 2017 with rimbrake so expensive like the new ones, that blow my mind, so again what happened when the new shimano o sram get old in 2027 or 2030 , how can you keep up your beloved bike in the future?
I’ve reached out to a couple of eBike battery repair places. It does not sound good.
Find the battery specs and replace the cells :)
replace the battery==Its all a gamble__my ultegra di2 front derailleur failed after 18 months..second owner so no warranty.. part of cycling..look how long the first battery lasted..10 years? thats a win
Shimano Cues ‼️😱
I would buy the generic replacement battery. You may be able to find one that has a higher capacity. The costs are the lowest, and the job the easiest. If it turns out to not be a good solution you still have the much more expensive options available. Sometimes the obvious solution is the best, sometimes!
We can’t even get into this battery pack without breaking it
@@Mapdec Oh! That is so wrong.
Collab time with UA-camr ‘jehugarcia’. The dude is an EV, solar and battery expert.
He could rebuild you a new battery. If there’s a workaround with the old existing battery you have.
All the complexity and cost would be a downgrade in my mind.
I would simply replace the cells in the battery.
Beyond my skill and liability insurance
If it were my bike I think I'd pay for the v3 battery upgrade.
Can you repurpose a power tool battery pack? I'm guessing the original probably has just a couple 18650 cells in it. If the original battery pack did not have Lithium Ion cells, it would be worth coming up with an upgraded pack that will still run the group set.
Possibly. It’s beyond my skills, no guarantee it would work, and every professional is on the clock.
@@Mapdec do you know what the nominal operating voltage is?
@@Mapdec it probably has some fairly standardised batteries inside eg. 18650. It would be worth having an electronics repair shop nearby opening it up and seeing what they think in terms of inserting standardised replacements - perhaps with a bit of soldering. Give them a budget of say 75£ - if they don’t think they can do it for that, then stop right there, and look at some of the other options. This option keeps maximum respect for the heritage and originally installed group set, and the worst case is you are probably down £25 for them having a quick initial look.
A thread on weight weenies suggests EPS v 2 cases can be opened - this from the 6 year old thread:
'Hi. Maybe someone here have any experience with replacing power cell in PU14-REEPS for new one?
My battery taking no charge after being discharged for some time. I have disassembled it and found that all 3 Panasonic NCR14400 batteries are completly dead.'
Thanks Paul. I can’t see a way into this V1 though without damaging it.
That’s a tough one, £399 for the battery is beyond scandalous, I’m sure someone at Campag had too much wine with their lunch when they set that price…
If it were mine I would be hoping I could integrate a Shimano battery somehow!
It seems that the decision to keep the bike as original as possible is already foremost in mind. If it were my bike and I'm known to spend ridiculous amounts on bikes that are not worth it. I'd bit the bullet and upgrade the system to the v3 and be damned. For 635 for even 8 years is only £80/year, which is a bargain really. Even new old stock batteries are around €435 even if you could find one.
This yank was actually thinking what would Mike Brewer do? He'd find a specialist to re-cell that battery pack and take us along on the journey. And we'd all be right chuffed to see a proper fix! 🤣😂
I’m searching. Do you know anyone?
@@Mapdec ua-cam.com/channels/J0-OtVpF0wOKEqT2Z1HEtA.html this is your man!
I would go for the battery but it would be great to rule out that something else is the problem, like a shortage/damaged cable that just bleeds out the battery, can it fall off the cliff from few thousands shifts to 50 so quickly? Well, I think all options require disassembly of the bike, so why not go with the easiest?
You are onto something with this. We did discover a bent pin that might be a short. It hasn’t really made much difference though.
@@Mapdec Engineer's mindset! Also keep the history of the bike in mind ... if it just started between two rides, it could be some weird cabling issue, if the bike was stored away in a suboptimal place for months, it might have just killed the battery, I've had that with a few (unused) devices.
105 Di2 would be my choice...
No rim brake version 😥
@@Mapdec Ha ha, you're right. Unfortunately. In this case I would use a mechanical groupset.
Latest battery..
What was the outcome?
Mechanical
Shimano R7000
I would not (and have not) bought and electronic groupset… 😂
A quality bike is meant to last as long as you want to ride it - not be made useless by a dead battery or a lack of access to an obsolete operating system…
I just bought one of the last ever 11 speed mechanical DA groupsets just so I don’t have to go electronic.
1 replace battery
Since its a ex team pro bike replace the battery only .
Buy x2 new old stock batteries (they'll only get more rare and one on/one back up'll see the bike good for a few more years).
All depends on whether the bike can still keep up with newer bikes. If not hang it on the wall, if it can, 600 quid isn’t that much compared to a complete groupset, let alone a new bike.
Buy a secondhand battery, disassemble the original and see if you can replace the cells
If you really want to retain its originality then I’d go upgrade to V3
Id ring up Graeme Freestone King of Velotech Cycling Ltd and ask if he has a NOS battery or if he doesnt he probably knows someone who does.
Umm it would still have been sitting on a shelf for at least 8 years now

You can find good deals on 11s ultegra di2 curently and forget any campagnolo nonsense
Athena or Record...
It would mean swapping chainset, cassette and chain too.
@Mapdec Cycle Works But it would be Campy and that's what matters. Plus you could use the Athena EPS. Makes no sense to get modern campy...

its a good shout
Check out keith wakeham channel on battery upgrade and replacement
Oh….
convert it to singlespeed
Open the pack purchase new batteries reseal and reinstall. People get too freaked out because it's electronic. They're just batteries...
Liability nightmare. Insurance risk assessment epic. Who pays if it doesn’t work.
This is why I would never buy a bike with electronics in it, even e-bikes are out of the question, it's ridicuolus how much these parts costs just... to be more on the practical side: it's probably worth trying to find an electro engineer of some sort maybe they have some simple solution. Those guys who can solder car parts or even make a hairdryer work again MacGyver style. :)
Reason #399 to ditch electronic. Reason #635 to ditch Campag. Electronic anything is a short life product. Expecting otherwise is just not reality. If you aren't ready to regularly spend the money to replace a shorter life component, then electronic is not the way to go.
Call it a downgrade. But convert to the best mechanical option the budget allows and buy some spares to extend the years. Downgrade in performance maybe, but this is no longer a performance bike. Sorry. Upgrade longevity and usability.
Performance bikes are like the athletes that ride them. They are incredibly expensive and the performance expires rapidly.
Break the bike Downs sell all the parts individually and then buy a new bike if this is not adoption just buy the £600 upgrade
