Mountainbike and a Shift Kit
Is it necessary to install a shift kit on a mountain bike? I understand that you dont have to install one but for performance and reliablity is the Shift Kit the way to go?
If not installed what are the symptoms that I should expect. With the shift kit what advantages are there?
Have not built the bike. But since it is going to be on the work station in pieces I dont mind taking the extra time to make it great.
