... for dirt roads and unpaved bike paths. I would probably mostly use 32mm tires, and may on occasion use 35mm tires. Down the road, I might add fenders to the offroad bike, but I may never put fenders on them.
My roadie will weigh around 18 lbs, with sidepull brakes that will work good. My tour bike (with bags and tools) weighs 36 lbs, with sidepull brakes that work good.
The offroad bike could weigh around 22 lbs. Is there any logic in having the same (sidepull) brakes on all three bike styles ... with an assumption there would be the same brake lever feel ... to have the same brake-reflexes for all three bikes?
From what I've researched, it appears that cantilever brakes are the preferred brake for offroad bikes. Why is that, and would this apply for an offroad bike with tires ranging from 28 mm to possibly 35 mm?
So, along with the generic question (recommended brake for offroad bike), what are the pros and cons of sidepulls vs. cantilevers ... for an offroad bike?
For example, while I've never used cantilever brakes, I've heard one comment that a rider's front cantilever squeeked and did not provide the braking power he wanted. The commenter did not specify bike style or tire size or wheel size.
