I have a 58cm Long Haul trucker with center pull cantilever brakes, and the bike comes with 700 wheelset. Im getting ready for a foot of snow tomorrow and cleaned up my 26 mountain bike wheels, put them in but the bosses for the brakes on the frame are too high to adjust the brake pads low enough (bosses are level with the machined sidewalls of the brakes. Am I out of luck tonight? Is there anyway to adapt the brakes somehow to get the right height at the pads?

What Im asking in short is what do people who put 26inch wheels on theyre 700 lht do for brakes?

Thanks, Lou

They buy a LHT that's made for 26" wheels.

^was thinking about going brakeless but and footing it as I wont be going fast, but I probably end up falling a few time. and norwood, great advise. Ill go right now and get one. douchbag

It's just not done for that very reason.

in defense, there is no good way to do what you're wanting, especially if the frame size is over 56 (the conversion frame size, you've already tried what i would suggest, and it didn't work, the LHT doesn't take disc brakes, i'm afraid you should just get a fatter tire for the 700c's . . . fatties fit fine : )

yourrealdad

Correct me if i am wrong (this won't help you) but can't you run disc brakes on any wheels size as long as the clearance for tire size allows.

Obviously the LHT doesn't have disc mounts, but theoretically.

norwood

Douchbag. Man, I haven't been called that for a while.

As an enlightened owner of a LHT, I would have assumed you already knew that only frames 54cm and under came standard with 26" wheels and frames bigger came with 700C wheels. However I think your swap is a great idea and you should go brakeless. You know, so you're not out of luck tonight.

if you mean can you run 26" in a 700c disc capable frame, then yes.

problem is BB is now lower - up to 30mm - you'll get pedal strike if you pedal thru a leaned turn

i busted my ass this way one. pedal strike lifted rear end, tire came down on sidewall, huge blowout, went down with witness, only pride hurt

long term you can fit larger tires and shorter crank to alleviate this problem

OP is SOL though - best bet is walk / public transportation

first time with the issue of brake bosses. Wasnt sure that frames were configured to the size of the wheelset theyre designed around. figured out pretty quick I was sol. I end up just giving my mountain bike that had been sitting for a couple years (that I took the wheelset off of) and gave it a good tune up. Nice to have it on the road again anyway.

and norwood your still a douchbag

yourrealdad

Yeah i have learned the hard way that I just don't need to pedal through remotely sharp turns. Too many times of catching my pedal, especially MTB. I am not racing so who cares if I stop pedaling.

I wasn't even thinking about BB height though, good call. The LHT already has a low BB height in the first place doesn't it?

"you're".
"you're a ******bag." There we go. Now Norwood can slink away with his tail between his legs, having been so effectively assailed by the dreaded d-word.

I asked the same question here:
https://www.bikeforums.net/framebuilders/500773-700-26-wheels-frame-change.html
There are some paul breaks that can help with that, but in my case the breaks bosses are in the level of the rim, which doesn't give me much freedom.
I have posted there some photos too.

I haven't been able to solve the problem yet.

Lou627

yeah like I said I gave it up. not worth the trouble for the 2 days i could have used them. Checked your thread out kfir and got the only solution which is to braze the bosses lower, which I have no intention of doing, I like my 700 wheels. Thanks

juggleaddict

nah, if you had someone that worked with metal, it'd be easy to make a little horseshoe bracket to simply extend mounts down from the existing mounts, but as you said, probably more trouble than it's worth unless you want to run them occasionally

Lou627

actually, good point. made me start thinking about some kind of bracket to attach to the bosses to attach brakes to that would put them in the correct possition. I work with metal (build custom choppers out of junk yard motorcycles), mulling over putting something together without having to add additional bosses. im not going to do it though, as i mentioned its 2 days that I really cared about this anyway.
