Ivan…with all due respect i did originally take it to a shop to have it re-cabled. $$$$ later and a result i’m not 100% happy with (limits weren’t set correct, chain rub, poor routing of the cables - they almost touched my knees!, the front der set screw wasn’t tight enough and it pulled out and pulled the crimp off!). Yes i could take it back but now i’d rather learn it for myself. I’ve researched the resources (Zinn, park tool online, etc) and spoken with a friend who used to own a bike shop so i’m not approaching this willy nilly.
While i may not be a bike pro i’m not a technically inept fool. I’ve got graduate level degrees in aerospace and mechanical engineering. If i can design parts for smart bombs i think i can learn to tune a derailleur. So please forgive me if i’m trying to learn a new skill so i don’t have to pay a bike shop some crazy fee the next time or god forbid i’m away at a race and something happens… i’d like to know how to fix my bike.
