i like to know if any thing the same thing happpen to you, and plz tell your fixe's


All the best ReTro bikes :shock:

super easy fix...you buy an XT 9 speed shifter and rear mech and some cable housing...and whatever cassette you want. job done.

Airines isn't really a practical thing, it was only ever designed as an innovation to try something different, and really only applicable to people doing DH shuttles and with someone with a pump at the bottom to recharge it.

hi now 2 set up for sale

it not done alot


thank you for reply

It sucks but it is cool. It last one down hill, that is the pourpose, not 3 hours of riding.

If it works fine and has no leaks, it is ok. Shimano have done it for a specific pourpose, not to ride as a normal system.
