Shifters
There is nothing
worse than missing a shift
in the middle of a really sick, but "doable" climb.
Start with the right group for you and keep
it serviced. Yes, it's as simple as that: that, and knowing
when and how to shift efficiently... nothin' to it!

NOTES:
Chains:
9 speed chains are 0.5mm narrower than
7/8 speed chains. With Shimano chain pins, the silver pins are
for 9 speed (6.5mm) while the black pin (7.1mm) is for the 7/8
speed chains. Sachs power links do not fit Shimano chains. Furthermore,
the 9 speed power links are narrower than the 7/8 speed links.
HG chain must not be used with IG cranks. 9 speed chains are HG
only. IG chains are ok for HG groupsfront 9 speed derailleur are
0.6mm narrower than 7/8 speed.
MISC:
Non- parrallax hubs cannot be used
with 11 tooth cassettes.
