Your extensive knowledge of everything Brompton is so impressive! I think you should do a Q and A video about your channel and we can all ask how you know so much and about how brilliant bikes channel started etc! thanks for all your super helpful videos :)
Love your videos! You're as perplexed as I am when you think you've done something right, but the bike is telling you you haven't! But I've successfully used your videos several times for maintenance of my chpt3. Keep calm and carry on!
Another helpful video - thank you. Some queries: There seems to be green Loctite or similar on the BB threads; won't this be negated by the grease? The axle is by FSA, apparently; what about the cranks (the Brompton branding seems to add a hefty price premium). Presumably, the chainring is aluminium?
Not facing the bottom bracket shell risks mis-alignment and premature demise of the bearings, knowing the tolerances most bikes are manufactured to I would consider this to be fundamental good working practise…..
I agree. Please advise what the alignment looked like on this install as there will be powdercoat on the BB shell which would have no bearing (sorry!) on the original BB fitted. I modded my Nickel Edition to external BB cups and removing the plating with the facing tool was a pain.
On a side note Mitchell Engineering in the UK - took a Rega arm and drilled lots of holes to lighten it. Wonder if that can be done on a brompton - probably not. But it would look and feel cool - yay - wheee
When I bought my Top, Flame painted "SuperlightM6LXBrompton" in 2019 (600mm seat post as standard in Scandinavia), I had my Ancient Type, square bottom bracket changed to my own, Chinese bracket from titanium with Ceramic Balls, at first "Free Service"! For now with much titanium and carbon additions and changes my bike weighs 8,5 kilo, and still with my mudguards, as a "Rainy Dane"! I expect with a carbon handlebar and more changes, also titanium brake parts, to be able to reach at least 8 kilo? The clamps on those guards, in spite of the original Titanium Stays, are made from "Heavy Metal", for which I have a set of Chinese made, Carbon clamps and Alu holders to be changed when the Danish "Day of Summer" arrives, eventually unexpected? I do like my bike to look as "Standard" as possible, not to advertise "Expensive Bike/Parts", so you are hardly able to notice anything Special on my bike (Though a Brompton is indeed expensive, even as "Standard"!). I do wonder though why English Bikes in GB are sold without mudguards, as the climate is only a fraction better and less rainy than in my home, Denmark? "The new set", is it able to use my one sided, Brompton Folding Pedal as before? The Prime Idea of a small wheeled and "Hard Rolling" Brompton is Transport as folded, and I would - hate being able to loose a Pedal during that!!! I intend to put my folding Pedal under my "drill tower" to add some extra holes in the frame, for less weight, as on also ancient racing bikes. I have seen Campagnolo "Brake Grips" given so many holes in them, that I wouldn't trust my dear life to those! But extra holes in a pedal hardly compromises strength? Finn. Denmark 😀
10:15 Another great video.. well done! You didnt mention the price.. a quick google says its around £250!! Is that right? Thats a lot of money for a 150g saving!! Think I'll leave mine as standard!
You don’t save much weight but i believe this design can handle more watt into it. Square taper is so old fashioned and best for leisure amount of power. The bb threading on the Brompton are not good from the factory despite their marketing. Ive been told the older ones have straight threading while newer one needs rethreading and refacing. I got into the habit while hand tightening cups on both ends, i would put the axl through the cups to keep the alignment while i hand tighten both sides. Then pull out the axl and tighten down and torque down if you like.
An expensive upgrade for not a lot of weight saving, and only available in 50T whereas the older standard one has 44T, 50T and 54T options. I also wonder about the ease and cost of replacing the sprocket chainring section. It's very easy on the standard spider and not that expensive.
Thanks for watching and taking the time to comment The superlight chaining is available in 50T or 56T - the replacement is "fairly easy" - we're going to make a video on that The chainring is definitely more expensive than the current (as used on Spider / C Line one) and not quite so easy to change / replace
Given the recent recalls from Shimano etc where do you stand on Carbon cranksets? How smooth is it when you have original crank with that bottom bracket?
You're funny. Air in tires adds weight? Bike doesn't weigh the weight difference after installing the new set? 😂 You can't use different scales like that unless they are very accurate and calibrated. Thanks for another lovely video! ❤
50T chainring is too heavy for 6 speed and too small for the 2/4 speed. Also, I think you can save about 100g just by replacing the bottom bracket to a titanium one without replacing the crankset.
Another well-produced video - efficient, informative and slightly tongue in cheek. As for the subject matter: is this really what Brompton spends its R&D budget on? In the real world this lighter crankset is an irrelevance, though inevitably it may become a talking-point in the cafes and wine bars of Chelsea and Putney. Also, as we sort through our collections of expensive specialist bike tools is it really necessary to remind us how to tighten a nut (“Righty, Tighty “etc). Have you yet decided whether the audience for these useful practical videos is more likely to be composed of capable d-i-y ers or children? Just off for a ride, as the BBC forecasters have said that the Mist and Murk will clear, there will be no Spits and Spots of rain, so I need not fear Dank and Drab conditions.
I suppose it becomes relevant when you replace tens of bike parts. This guy, in New York, spent almost US$10,000.00 to make his T-line weight 7.03 Kg. - ua-cam.com/video/76pMyBkm3V8/v-deo.htmlsi=7RIxZ4YJd_CDE5Z8
Yes it is, but you need a special tool and vice. We will show how to do the upgrade when we do a change from 50 to 56 tooth chain ring. Thanks for watching!
Technically BB is hollow and axle is connected to the crank itself, I wonder what’s lightest square taper BB is. I’ve switched to Shimano UN300 which apparently is 10g heavier so not it.
I think it's one of those where if you're upgrading just because then it's a bit meh. if you're replacing the stock one because it's knackered then you might as well.
Hi I’ve been facing the issue of creaking sound coming from my Brompton SL6 especially while pedalling on climbs and from that point it continues.. I’ve changed my pedals, sprocket but still the sound persists, wanted to understand what could be the issue here.. pls help on this
My first thing would be to grease the suspension block, it’s a common cause of creaking. One of our older videos explains this. Hope that helps and let us know how you get on! Thanks for watching!
Thanks for watching - and the question Yes - it is also available with a 56T chain ring The chain ring is interchangeable We will be doing a ‘how to’ change up from 50-56T video soon (That also needs a longer chain)
Crank set: super light 650g = standards 650g (the same? How come? The super light is made of carbon anyway, isnt' it?). And BB: super light 101g < standards 269g (168 grams heavier than super light version). So the super light carbon set is lighter than the standards by 168grams. Am I missing something in my math? I can't get 260 gram difference at all.
You are right. The “Super light” crank appears to weigh the same as the standard crank set only because the “super light” includes the axel. Where as on the standard the axel is an integral part of the BB. And yes your maths is right, the overall weight saving is only 160ish grams, not the 260ish stated.
Great question, I guess. We will find outing due course, but I can’t see it being any different to the standard crankset, as at the moment it is the same size. Thanks for watching!
I just go to the loo before a ride, thats nearly a kilo in weight saving straight away ;o)))))
I too go to the loo before a ride after upgrades to be even lighter 😉🙃
Thanks both for making me laugh and for watching!

I think for all the faff I’ll stick to the stock crankset. Seat post and pedals are enough. Love the vid tho’ Hannah.

I wouldn't do this for weight saving.. but to have 165mm cranks and oversize BB-bearings I would!
Love the Allen key set!!
They are absolutely brilliant! Nice colours but also Allen key plus so have extra engagement!
Thanks for watching
919g - 751g = 168g lighter not 'about 260g' as stated when you weighed the cranksets!
Big thumbs up, for sure! .. but the weight savings is dismal.
We really thought this would be a great weight saver!
Thanks for watching!
Thanks for your channel, I would love a chapter 3 but I’m no paying silly money for one. Are they going to make anymore? Thanks
Many thanks for watching! Fingers crossed there will be one this year

Damned weighing things!
Thanks for watching!
The carbon cranks + chainring are the same weight as the normal ones? That can't be right can't it?
50T chainring is too heavy for 6 speed and too small for the 2/4 speed. Also, I think you can save about 100g just by replacing the bottom bracket to a titanium one without replacing the crankset.
Does the carbon crank feel any stiffer than the standard crank?

I think I could use almost any crankset with 68mm BB right? Or does the Brompton has a special chainline?
Is the chainring replaceable? I’d like to get this upgrade but not if obtaining replacement chainrings will be problematic in the future.
And are other sizes available for those who like lower gears?
Yes it is, but you need a special tool and vice. We will show how to do the upgrade when we do a change from 50 to 56 tooth chain ring.
Thanks for watching!
Unreal so you get no weight saving from the crank set just the BB so save time and money and only swap the BB. That's interesting 👍🏻
Technically BB is hollow and axle is connected to the crank itself, I wonder what’s lightest square taper BB is. I’ve switched to Shimano UN300 which apparently is 10g heavier so not it.
Any option on crank length? 165mm is that an option? Or are we to just get what we are given?
Plus one for this query! A bike that is intended for such a wide range of physiques should offer a range of crank lengths.
@@eegaugh Absolutely!
Nope it only comes at a single config. 170 if not wrong
I think it's one of those where if you're upgrading just because then it's a bit meh. if you're replacing the stock one because it's knackered then you might as well.
Thanks for watching!! A nice upgrade if you are after one!
@@brilliantbikes Totally.
Hi I’ve been facing the issue of creaking sound coming from my Brompton SL6 especially while pedalling on climbs and from that point it continues.. I’ve changed my pedals, sprocket but still the sound persists, wanted to understand what could be the issue here.. pls help on this
My first thing would be to grease the suspension block, it’s a common cause of creaking. One of our older videos explains this. Hope that helps and let us know how you get on! Thanks for watching!
A loose saddle will also creak.
Can you get this in configurations other than 50T?
Thanks for watching - and the question
Yes - it is also available with a 56T chain ring
The chain ring is interchangeable
We will be doing a ‘how to’ change up from 50-56T video soon
(That also needs a longer chain)
The weight of the air in the tyres? Who are these people? That would make no significant difference to the weight in any practical way.
True. When you buy veggies at the market, you don’t squeeze the air out of the bag lol
Thank you both!
Now we need to try it…..
Crank set: super light 650g = standards 650g (the same? How come? The super light is made of carbon anyway, isnt' it?). And BB: super light 101g < standards 269g (168 grams heavier than super light version). So the super light carbon set is lighter than the standards by 168grams. Am I missing something in my math?

The cranksets is the same weight regardless stock or carbon hence if changing the lighter titanium bb taper square will be the same weight 😅
150g ?
Can you please bring back out the " Hippy Outfit" thanks
😂 it will make a special appearance for a future selected video!
Thanks for watching!
@@brilliantbikes Great 👍
Weight saving during unboxing comparison was 26ogm. But final result weight savings only 150gm. Why the difference?
We were also surprised!!! Not 100% sure, perhaps k no or a sensitive enough weigh scale to start with
Thank you for the prompt response. "Some things in life has no answer". But I have been enjoying viewing your videos. Keep it up. @@brilliantbikes

u sound so disppointed with the weight saving after all the work.. hahahaahah
i still prefer 3rd party crankset haahaha
I was I so expected more! Thanks for watching!
I checked with the local Brompton shop and they said cannot be installed on the p line. 😂
😂 funny that’s what we installed it on and it even says on the Brompton instructions that it can
What is the top speed? 🚴🚴🚴
Great question, I guess. We will find outing due course, but I can’t see it being any different to the standard crankset, as at the moment it is the same size.

260g lighter; it can only be justified if the plan is to send it to space!
