Hello RJ, I'm putting a fork for 26" wheels on my son's 24" wheel bike since I can't find a decent 1" steerer suspension fork for it. Do you think the second set of adapters you showed will work upside down to move the v brakes lower? Thanks
It works with the road bike breaks I think they're call caliper breaks. By the way your videos been giving me more free knowledge, I always fixed my bikes since I was 12, I'm not a bike repair guy but I can take apart a bike and put it back together the only thing I'm not good at, is fixing the rims, which I know I can learn how to work on them with your videos. Thank you for all that knowledge, knowlegde is power.
i wanted to see you change the fork to the ridged fork i have a bike like this i converted it to 700c wheels but i want to change out the shocks for For a ridged fork i needed to see you do that and show me how to do it great video though i was looking forward to seeing how you would change it to a ridged fork
I've done this to several mountain bike frames, mostly disc so as long as the wheel and tire fit, easy conversion. The one V-brake I converted I found another idea online; just a steel bar that bolts to the shoe arm hole and then the shoe goes in the top hole, done. Seemed plenty strong ever afterwards but the old Mavic arch looks like it would retain absolutely ALL the stopping power for sure.
When I saw the Mavic adapter it reminded me of a thing I bought for my bike. When I noticed that my frame was too weak for my v brakes to engage properly, I bought a brake booster from ebay. Like the Mavic adapter, it could slide side to side on the bolts. I didn't want it to do that so I took a hoseclamp, folded it 3 times in an accordion shape and filed it to fit in the holes. The modified hose clamps works as a stop for the v brake bolts so it doesn't slide and put strain of the frame. My v brake is very strong now. P.S I'm gonna buy that Craftsman vice-grip-wrench, it seems like an heaven sent tool for annoying bolts and such.
I love your videos because you inspire people who like to work with old bikes, used parts and cheap solutions. Im also building a gravelbike at the moment.
I like the geometry, I usually put a 435 or longer rigid fork on front, higher gearing and for a while one could get some high end 26er frames (ones that had both wheel clearance and room for at least a 46 big ring or even a full compact) on closeout and build a very nice gravel grinder.
Thanks for this advice...i usualli build my own bikes, and many times the idea of getting longer rims on a 26"frame came to my mind and allways the brakes issue came across...now I know a solution.
When I seen the title of this video I was thinking who will want to do this. After watching maybe I will try this. I do have a specialized with rigid forks & cantilever brakes. All have to do is find the wheels.
Cool conversion! I personally liked the other adapter vs the Mavic one, but the Mavic adapter is definitely easier to install and will work if you can't remove your brake studs.
You should have left the 26" wheel in the front and mount some aero bars ad patent the whole concept. Time trial mountain bike!! 100% chance of injury :)
Great video! I have converted my old 1995 Rocky Mountain Hammer to a kind of touring/commuter bike with thin 26x1.25 street tires, drop bars, 105 brifters, dynamo hub, road gearing, tubus carrier rack, but finding fenders that fit is almost impossible - the tires are so far away (almost 2") from the frame. This might be the solution I need to finish off the conversion. Thanks!
This was a fantastic video, very informative. Now you've got me thinking of changing the wheels out on my 16 year old Supercycle XTI 18. Nice craftsman wrench. CDN Tire for the win!
I think converting to 650b/27.5 would be a better approach. Nowadays, with the rising popularity of gravel bikes, there are so many choices of tires available for that wheel size and the slightly smaller diameter gives you a bit more clearance to play with. I would only consider a 700c conversion if it was a frame with no chainstay bridge, like a Bontrager or a mid-90s Raleigh Ti frame. If the frame already has disc mounts then going with disc brakes is a given. For frames without disc mounts then, either Paul Motolite v-brakes or, if you're on a budget, then there are BMX v-brakes that are designed to accommodate multiple wheel sizes. I remember back in the late 1990s, seeing riders running 650b wheels on their MTBs for racing on the H.P.R. figure-8 velodrome. They were using the Paul Motolites to make the conversion.
I was looking at doing this on my mountain bike as well and was looking at the limitations of the existing cantilever brakes. I was foolishly looking around for cantilevers that adjusted up to 63mm from the posts - obviously didn't have much luck. I should have known to check your channel for a vid on how to go about doing this. Thanks for the vid.
I have put 27.5 wheels on a 26 MTB and there is a noticeable rise in the bottom bracket height. The cross bar is correspondingly higher too. 700c is equivalent to 29 so mounting and dismounting may be exciting 😁
Thanks! I'm going to make a Frankestein bike off scrap parts with 700 touring frame and wheels, mtb gears and 26'' suspended fork. I think i'll mount calipers brakes.
Maybe a 650b wheel is more appropriate for a conversion. This would allow more clearance and usage of all 650b gravel tires as 26" is going out of business at tire manufacturers. The small adapters are all over AliExpress by the way... ! 😉
RJ-drinking game: Rules, every time RJ says 'there', first one slams the table have to say a name of the person that will drink a sip of his/her beer. BUT if he says 'here' last one NOT slamming the table drinks. If neither and you slam the table, YOU drink. It's quite fun! Try it out.
Avid speed dials are great for running mixed brakes. A lot of v brake lever combos have plastic blocks that can be moved to select Canti pull or v brake cable pull distance.
Amazing, I was wondering if it was possible to convert but always dismissed it because I thought I couldn't fit tyre wide enough. But now it's time to go measuring.
I'm still on the fence about this conversion for my 26" bike, mainly because I'm not sure whether 700c wheels would fit the frame. If I could source some good second hand 700c wheels, I'll definitely give it a try.
Would those little brake post extenders work "in reverse?" As in, would they help lower the brakes rather than raise them, if they were positioned downwards instead of upwards? I'm basically trying to find a simple 700 to 650b conversion solution (...aka downsize my rims) but I'd love to keep my same brakes if possible...
29 wheels are much Better than 26. You'll travel farther with less effort I'm glad it's possible to convert 26 to 29 cause all my 4 bikes are built on 90s chromoly frames and the standard size back then was 26 so they're all 26
Hey RJ the bike guy I wanted to thank you for this video I just got some rims for my bike and they're 27.5 my bike is a 26in and I wanted to put my new rims on my bike so you definitely answer my question now I just go ahead and do it thanks again keep up the good work :-)
Boy , you combine the drop bar conversion and 700c wheels and you can make any of the high quality older mountain bikes into a touring machine. I have an older Trek 970 I picked up a while ago which would be a canadite. PS the older trek's 930s. 950s and 970s have rack mounts. , fender mounts , and made in USA Trutemper good frames to name s few. Also I hate toe overlap so would have to check that.. Another thing to consider I guess is the type of riding . Obviously the more road you do I guess the 700c might be better, the more trail the smaller rim bigger tire might be better on the 650
I am in the process of doing this conversion to an old Cannondale mountain bike. This video was the answer to my question. Thank you. Those Mavic adapters are very hard to find but there are a couple manufacturers of those other adapters. do you know of any V-brakes with a longer than average adjustment so that maybe you would not need an adapter.
thanks for these cool conversion ideas. i think you are the only one who does these in depth conversions that i have seen. it would have been great however if you were to do a test ride after and comment on how the conversion actually affects the ride-ability and handling characteristics of the bike after such a conversion. otherwise, great videos and keep up the great work.
thanks for replying. i guess i was mainly wondering if your foot hit the front tire while turning because of the bigger wheel since you mentioned it in the video.
I reckon your your skill on bicycles of all flavors does come close to a flying submarine experiment, but how safe for daily use is it? I believe you confirm that safety on bikes goes first. Mind bogles on your effort invested to make a inch difference on tyres diameter. Big thumbs up!
Juraj Grossmann please explain how this swop can affect safety,I’ve done this swop both ways (no difference apart from thinner tyres (less grip) maybe you should try it then you’ll know what your talking about.
i know there is preference and taste, and there is maybe also some rationale to extend the tires by inch, meaning if you can produce the torque to use it. looking on how the tires are close to the brakes edge i was a bit puzzled on how you would mount em preassured up. just my 5cc
One thing I've noticed about newer bikes vs bikes like this from around 20 years ago is that the rear triangle of the older bikes are typically a lot beefier. on some of the newer bikes the rear looks paper thin, particularly the seat stays. What is your opinion on that trend, are the beefier rear triangles from yesteryear better or the newer, more forgiving modern frames that look like they have a lot more flex to them?
I’m not sure, but my 2cents go for a combination of 3 factors. 1. Rim brakes, be that v-brakes or Magura HS, put all the braking force sideways on the seat stays. So the seat stays have to be stronger. They are having to support the compression from rider weight and wheel impacts, while being “pulled apart from each other” by the rim brakes, or bending them. They could buckle if they weren’t strong. So since disk brakes were mostly optional, the frame manufacturers had to make seat stays adequate for both brake types. 2. Rim brakes eventually got phased off from newer bikes. So this meant that all the stiffness that the seat stays had to support the rim brakes wasn’t needed, and this came about the same time that the biggest previous and ongoing trend was lightweight. So if rim brakes aren’t supported, there’s no need for the brake post attachment points and the added stiffness for the rim brakes effectiveness. The frames got lighter, simpler and sleeker, but less compatible. The rigidity goes to the last point. 3. Less rigidity isn’t necessarily bad. Obviously pedaling on something that feels made out of spaghetti isn’t very pleasing. But, the evolution of manufacturing allowed for choosing which rigidity is built into the frame. So the seat stays can be stronger sideways for cornering, but maybe a little softer to vertically help with comfort over bumps and impacts. Or a mix of both directions. But that would either remove the braking effectiveness from the rim brakes, because the stays would just bend instead of putting pressure on the rim, or, complicate the construction of the seat stays and add more weight or manufacturing cost. Maybe, IDK. Disk brakes do not have such issues because they are assembled in areas of the frame that are very strong in any case, and if not, it doesn’t take that much material to reinforce the disk brake mount. Rim brakes are very far away from any possible reinforcement. And it is always a balancing act, to make the rim brakes better, the frame would be less comfortable because it would loose compliance. But I absolutely love my HS33. Did about 2000km on them, on road, gravel, respectable mountain biking, mud, rain, dirt, and I’m not a light guy. And everyone was very surprised on how strong the stopping was with those brakes. They await for their chance to get reassembled in another bike for my enjoyment.
I had 26x2.5 tires on my mtb and 700x23c tires seem to be the same diameter. Like the 700c rims are bigger but since the tires are small the total diameter of the rims with the tires installed seems nearly same.
Really good video !!! I've been looking for one like it.thank you for the upload 😀i have a Specialized stumpjumper from the 80s .26" I've put 27" and have tons of clearance.i now have to figure out brakes.will these adapter's work for me ? The original back rim split ,I've seen where you can weld it but after riding on 27s I like it.
Could you do this but on a less extreme scale? I'm thinking about fitting 27.5s on my GT outpost from 1995 after adding a fork. I would love to see you do a video on the subject!
I bought a 26" front hub motor ebike kit. But I'd like to look around for a different used bike to put it on. Currently have the kit on a Schwinn Sidewinder ("Women Inspired") with a SUNTOUR aluminum shock fork (not tapered). I'm wondering what my limits are if I want to go wild and frankenstein something together. I assume I could buy a bike with 24" wheels and change out the front fork to 26" - am I right? But, what if I found an old BMX type bike with 20" tires - could I put my 26" forks on that frame? Not that I particularly want to do that - just trying to determine how universal forks are.
Hey curious question im wanting to get a electric motor for my bike but only issue I’m worried about is I have a giant mountain bike 27.5” and the electric wheel is 26” would it work. I know probs a really dumb question but I need to know.
Hey RJ, there are some brake calipers which have a long adjustment too. Got a pair of ice jaw v2 bmx brakes on my mountain bike just for this purpose. Think Pauls will do it as well
Another problem I see with this is mud clearance. If your going down a muddy trail, your tyres are going to get caked in mud and stop your wheels from turning. if your using the bike as a commuter bike though I guess its ok.
Would you consider posting a tracing of the Mavic Caliper Adjuster for 700C wheels so I can fabricate my own? (I am giving up finding the manufactured part.)
I hope all is well, but I can not get the adapters, the ones used I have been told are to short and for BMX bikes. None online. Considering how many there are for disc brake is shocking
Hi! Great video, very useful. I'm trying to do the same thing (700 wheels on a 26" MTB) but it's hard to find adapters like Mavic's. The studs in my frame are welded, so I don't know how to use the second type of adapters you've shown in the video. Any suggestion? In the meantime, I'm trying to contact the Taiwanese Mr.Control company, It seems they have a Horseshoe adapter but I can't find a place to buy it. Thank you for all!
Hey RJ, hows the brake flex using the promax post extenders? i'd assume that the vintage mavic extenders have significantly more support with the arch, acting similar to v-brake boosters, and not have any excess flexing
You mentioned that these wheels were already 135mm what kind of bike did they come off of? I’m struggling to find a set they are all road 130mm hubs or disc brake setup
Hi bro Im currently riding MTB 26 inch and would like to convert it to hybrid. How to go about it? Can I change the tyre only or how? Pls advise, thank u
Interesting for sure. But also, why? What's the practical application? I see plenty of drawbacks, especially on this bike. As mentioned, there's the possibility to clip the front tire while turning, but also there is now less travel in the suspension. With a rigid fork, I could see this being more practical (especially if there is rake in the fork), but I wouldn't do this on a suspension fork.
Long pull v brake levers not compatible with caliper brakes. I don't necessarily agree with that. I use Tektro v brake levers on Shimano RSX caliper brakes and they work fine...no problem at all.
@@RJTheBikeGuy They are less progressive...but braking effort is no less effective than my other bikes. The difference is marginal. I'm just telling you how it is in my experience. I own 9 bikes and built many of them from frame up and I ride 250klms a week. I understand braking performance. Really enjoy your vids by the way...very instructional 👍

But that would either remove the braking effectiveness from the rim brakes, because the stays would just bend instead of putting pressure on the rim, or, complicate the construction of the seat stays and add more weight or manufacturing cost. Maybe, IDK.
Disk brakes do not have such issues because they are assembled in areas of the frame that are very strong in any case, and if not, it doesn’t take that much material to reinforce the disk brake mount. Rim brakes are very far away from any possible reinforcement. And it is always a balancing act, to make the rim brakes better, the frame would be less comfortable because it would loose compliance.
But I absolutely love my HS33. Did about 2000km on them, on road, gravel, respectable mountain biking, mud, rain, dirt, and I’m not a light guy. And everyone was very surprised on how strong the stopping was with those brakes. They await for their chance to get reassembled in another bike for my enjoyment.
Great video that show me lots of ideas. God Bless You
Just looked. Mavic adapter used $199.99, other adapters $15-$40.
I had 26x2.5 tires on my mtb and 700x23c tires seem to be the same diameter. Like the 700c rims are bigger but since the tires are small the total diameter of the rims with the tires installed seems nearly same.
Really good video !!! I've been looking for one like it.thank you for the upload 😀i have a Specialized stumpjumper from the 80s .26" I've put 27" and have tons of clearance.i now have to figure out brakes.will these adapter's work for me ? The original back rim split ,I've seen where you can weld it but after riding on 27s I like it.
Could you do this but on a less extreme scale? I'm thinking about fitting 27.5s on my GT outpost from 1995 after adding a fork. I would love to see you do a video on the subject!
I am not doing videos from every size to every other size. Try it. It will work or it wont.
i just converted my Norco Indie 700c commuter to 650b to ride trails, and the tires end up being the same total diameter
did you use those little adapters to lower the brakes?
I bought a 26" front hub motor ebike kit. But I'd like to look around for a different used bike to put it on. Currently have the kit on a Schwinn Sidewinder ("Women Inspired") with a SUNTOUR aluminum shock fork (not tapered). I'm wondering what my limits are if I want to go wild and frankenstein something together. I assume I could buy a bike with 24" wheels and change out the front fork to 26" - am I right?
But, what if I found an old BMX type bike with 20" tires - could I put my 26" forks on that frame? Not that I particularly want to do that - just trying to determine how universal forks are.
Are all post of vbrake mount to screw out?
What of the 2 mounting is the better?
Pls do video on how to install RB crankset to MTB frame. Thanks in advance 😊
Remove MTB crank and BB. Install RB crank and appropriate BB. Install new appropriate sized chain. Maybe adjust FD.
Nice modification details...
Hey curious question im wanting to get a electric motor for my bike but only issue I’m worried about is I have a giant mountain bike 27.5” and the electric wheel is 26” would it work. I know probs a really dumb question but I need to know.
I just put a nice old m marzocchi 26in on a 700c road bike. I'm waiting for those ebay extra long reach v brakes .
Thank you for all your videos. I've learnt so much from you.
Hey RJ, there are some brake calipers which have a long adjustment too. Got a pair of ice jaw v2 bmx brakes on my mountain bike just for this purpose. Think Pauls will do it as well
Yeah, I have seen them. I question how well they will work with very little leverage.
They're not bad but I know what you mean. I wouldn't want to use them with worn pads.
Hi rj have you ever thought about doing a video on how to install rod brakes??
On a bike without them?
Where did you get the relocation devices? I’m trying to convert my own 26” to 700c.
what about when you ride it. wil the rear adapters handle all the torque when you press the brake hard ?
Rj can u do a 28 to 26 conversion please......
is it possible to mount those brake post extenders in reverse to fit a 26in wheel in a 28in frame? ....also what about 650b?
Do those adapters work backwards? I have 700c narrow road wheels and I'd like to use some 26" mountain bike wheels/tires
Another problem I see with this is mud clearance. If your going down a muddy trail, your tyres are going to get caked in mud and stop your wheels from turning. if your using the bike as a commuter bike though I guess its ok.
False. Friction will happen, but "braking" will not.
Ok yes it wont cause braking force, however it will cause a LOT of friction slowing you down lots.
I was waiting for you to tell me how bad are Mercedes-Benz cars and how much you hate electronics
With Alibaba stuff you can do any conversion
Would you consider posting a tracing of the Mavic Caliper Adjuster for 700C wheels so I can fabricate my own? (I am giving up finding the manufactured part.)
Anyway one could replace the V-Brakes by mini V-Brakes to make them short pull (and makem them compatible with Road STi's) ?
I hope all is well, but I can not get the adapters, the ones used I have been told are to short and for BMX bikes. None online. Considering how many there are for disc brake is shocking
Can we drill a hole in a steel fork ?
drop your spring so you dont fighr un wwnted tention do that last when you set balancing screws
Hi! Great video, very useful. I'm trying to do the same thing (700 wheels on a 26" MTB) but it's hard to find adapters like Mavic's. The studs in my frame are welded, so I don't know how to use the second type of adapters you've shown in the video. Any suggestion? In the meantime, I'm trying to contact the Taiwanese Mr.Control company, It seems they have a Horseshoe adapter but I can't find a place to buy it.
Thank you for all!
RJ that’s rad! what wheels would you recommend to do this with disc brakes? Might give it a go.
Hey RJ, hows the brake flex using the promax post extenders? i'd assume that the vintage mavic extenders have significantly more support with the arch, acting similar to v-brake boosters, and not have any excess flexing
They seemed to work fine when I test rode it.
Also, I never see guys lubricating the pivot points on brakes?
Could you check to see if the KENDA KWICK 700X30C would work.
You mentioned that these wheels were already 135mm what kind of bike did they come off of? I’m struggling
to find a set they are all road 130mm hubs or disc brake setup
Yeah, the same issue for me.. I have a steel frame, so I widened the rear fork. It works!
FOR REAR BRAKE THE PLATE ADAPTATOR IS BETTER FOR MORE BRAKE ....
THAT MAKES IT MORE RIGID ...AND DISTRIBUTION OF BRAKING IS BETTER DISTRIBUTED
Sir, my bike is Large Frame but 26 inch wheels, im 6'2, would a longer seat post work? I dont my knees hurt
Hi bro Im currently riding MTB 26 inch and would like to convert it to hybrid. How to go about it? Can I change the tyre only or how? Pls advise, thank u
Also on brake calipers,wouldn't bmx brakes work?
Please talk about nut's key I never see this tool
Sorry for mi english
Best regards from spain
Send to me the links of the wheels that you use. Thanks
Interesting for sure. But also, why? What's the practical application? I see plenty of drawbacks, especially on this bike. As mentioned, there's the possibility to clip the front tire while turning, but also there is now less travel in the suspension. With a rigid fork, I could see this being more practical (especially if there is rake in the fork), but I wouldn't do this on a suspension fork.
This would not affect the amount of suspension travel.
RJ The Bike Guy wouldn’t the wheel hit the frame? Think I chose my words poorly.
I have tried the long reach v brakes. Not enough braking force, since it changes the leverage.
Really interesting and helpful video as always thank you.
Any problems after changing the tyre size??? Pls tell me
Can you please do a video on how to upgrade from a 3x9 to a 1x11 or 2x. Thanks

Nice job! I’d still be worried about your foot hitting the front wheel though...
Fit smaller cranks and adjust the ratios f/r to suit? Agreed, for off-road this is indeed a concern!
Good for gravel riding.
Long pull v brake levers not compatible with caliper brakes. I don't necessarily agree with that. I use Tektro v brake levers on Shimano RSX caliper brakes and they work fine...no problem at all.
You will have less braking leverage. That is physics.
@@RJTheBikeGuy They are less progressive...but braking effort is no less effective than my other bikes. The difference is marginal. I'm just telling you how it is in my experience. I own 9 bikes and built many of them from frame up and I ride 250klms a week. I understand braking performance. Really enjoy your vids by the way...very instructional 👍
What 700c tire width is the maximum that will give enough clearance between the wheel and the 26er frame?
Sorry, you have to measure and go by trial and error.
Hi RJ what size your fork?
can't you just swap the tires out for road bike tires?
Hello mr rj bi e guy, thanks for those great videos & homemade tools, could you make a video with the crank & piñion for a beach cruiser, that give a confortable ride & not too much efort on small hills in th neighborhood, thanks, good job. Joe.
If it's a single speed you may or may not be able to lower the gearing.
You've gone to skinnier tires with less sidewall height, more uncomfortable ride, and more likely to bend a rim.
People asked how to do it. Personally, I don't recommend it.
@@RJTheBikeGuy Hey I was just enjoying your video, didn't even realize I commented on it, pre-pandemic! Seems like ages ago! Hope all is well.
