I just changed tires on my old yellow MTB from 2.1" knobby tires to 2.0" tires with more of a hybrid tread. Despite that it seems like the clearance between the tire and rear v-brake cable is much less than before. Could these actually be taller (larger circumference) than the knobby tires? Is there any reason to be concerned about this minimal clearance?

advertised size is just that, an advertisement. many tires vary widely in actual dimensions for a given spec. if it clears and the brakes don't rub, then you're fine.

Adequate..

Cool, I'll try not to think about it.

The old 2.1in may have referred to the size with knobs which had worn down. There's really no standard way to measure tires (other than at the bead), and it's even more confusing with knobby tires.

Magura HS33 Is a Better Brake IMHO HS33 R*| MAGURA it has no cable across the tire.

One way is to measure casing width and knob width on a stated rim width. Start there.

yeah no, one brake costs more than I spent building this entire bike.

I got mine when I bought the Bike WB Bicycle Gallery: Robert Clark's Koga Miyata WTR

Well apparently the end of the linkage holding the cable noodle does in fact touch the tire when I pull the brake lever. And out on the trails this tends to happen:



Not sure what I can do about the brake touching the tire.

You can always Go Back to Cantilever brakes like the bike frame was Made to use , or a narrower tire ..

complaining and doing nothing is quite affordable then

Bike has never had canti's on it. It was originally built with the old Shimano XT brakes with the parallelogram linkage.

So what do you think this is?

I know it can take canti's I'm just saying it was never built with them.

Then Why is the center pull brake hanger there?

What year did you buy the bike?


1995 KHS Alite 1000 with cantilever brakes.




Was the Chang Star 877AT a cantilever brake?

Any one notice the different angle the pad nuts are at? Andy.

Obviously the urban tyre has a more rounded profile than the nobbles, I've noticed in the past that different Vee brake manufacturers can have slightly different arm lengths, might be popping to your LBS with a ruler & having check around on some bikes.

Yeah. And cantis will be trickier to get right.

That is one ugly monstrosity.

And a combine-thresher corn harvester is a thing of Beauty?



Form follows function.. remember parallel push ?

Shimano tried and failed to make a brake that had a linear motion to the rim.
(so pad wear did not change the rim contact like it does when the pad swings around an axis.)
all those linkage pivots loosened up with normal use & got sloppy.

Magura succeeded and they've been making them in Germany for over 20 years ..

New is a center bolt mounted aero brake for narrow tire bikes ..

Only for those who aren't practiced at this sort of stuff. Andy.

I bought it in 2007 from the guy who originally custom-built the bike from the frame-up with Chris King, Shimano LX/XT, RaceFace and Real chainring components. It had the Shimano parallel-push brakes on it originally when I bought it. ^^^ That's actually the first time I've ever seen another of this same frame, same color. I was never able to find the exact info on BikePedia about it before. I guess it's been updated since last I looked.

However, literally nothing on those BikePedia pages matches what this bike was originally built with. Seat post and stem look the same but that's about it. Even the RockShox fork is different.

So Not an OEM Build, the other guy spent the bucks and bought Higher cost parts.


OK now You tried your own custom build parts Pick changes and were not satisfied .

Now You try something else .

I vote cantilever brakes since you already have the housing stop there. And if it still gives you problems use something like this.

Decent cantis are super cheap ('cause no one likes them anymore apparently.)
