| Whats the difference between front and rear innertubes-?
Heh heh lolz!
-Not a lot, as far as I know. What I am wondering about is disk brakes,
however.
......
I have a rigid-fork bike that has 51-mm disk mounts on the frame and
fork. The mounts both appear to be the same. This bike currently has rim
brakes on it and I want to put disk brakes.
....but I see that disks are sold in "front" and "rear" varieties. What's
the difference? I am aware of the suspension forks that use post-mounts,
but the only disk brake examples I have on hand (Avid BB5's) appear to
be made to either use the 51-mm adapter or screw directly onto the fork
posts, and the brakes I want to use are BB7's, which also appear to
mount the same way.
So what I am wondering here is, for this bike (that does not have post
mounts on the fork), should I order a front and a rear brake? Or should
I order two rears?,,,,Since the fork has the same mounting bracket as
the frame, I will need 51mm brackets for both brakes.....
