Wheel & Cassette Width

steve23

ok, i bought some new wheels (campag shamal) that i intend to use on my road and time trial bike, and use my old wheels (mavic aksium) to train on.

but, i think that they are different widths on the rear wheel. both have the same cassette on, but when i put my shamals on my road bike, i had to move the brakes, and re-adjust the gears. when i then put the aksiums in, now they are not changing gear correctly.

i hope this is making sense!

so, my question is, if i buy a pair of cheap campag wheels to train on, will they have the same spacing and width as my shamals, so i can then swap the wheels as and when trouble free???

thanks

"i had to move the brakes"

How, in what way, exactly? I can't see how the OLN can be different, so if the wheel is sitting the same between the stays then the braking contact should be the same. I'm trying to imagine how the dishing could be different - but failing!

Think I better give up....

i had to move the brakes

sounds like the 2 wheels are not centered properly - that means the rims are not exactly in the middle.
get them checked at lbs
(or your fork is out of alignment)

and re-adjust the gears

would mean the cassette is placed differently on each wheel axle.
get lbs to check when looking at your rims
