Hi guys ,

How do I work out what size front Mech clamp I should get if I can’t get to a bike shop ?

It’s a 2 x 10 set up with a 27.2 seat post.

I’m building a Charge Cooker Ti and am looking for either XT or X7 but there are so many to choose from .

Any help would be great .

Many thanks

Do Xt mechs still come with the shims to fit all three diameters?

A quick google suggests yes for xt but x7 you need to know the size so measure with calipers it will be 28.6,31.8,34.9 the x7 is available in a huge 38.2 as well
