Initially they had major difficulties with sourcing a replacement XM317 Disc rim so I told them that a XC717 Disc rim would b a fair compromise. Its a similar profile to the 317 and happens to be lighter which is an added bonus. Even after this they were sent the rim brake version of the 717! A new rim was ordered again...
So, after several weeks of disappointment I finally got my wheel back on Thursday. I got a rim upgrade at no extra cost plus they did the assembly FOC. All I had to pay was the £16 for the spokes they used. I have to say they have been really great and more than made up for the situation in the way the compensated me. And Peter who runs the shop is a fantastic bloke. Really passionate about anything pedal driven. Thanks to all at Future Cycles.
