Apologies for the lack of responses, but....
I have finally, after a lot of searching, got all the bits for this bike together.
It's almost perfect aside from the grips and the bars but for now we have it!
I'll post some photos tomorrow but here is the spec:
2013 GT Xizang 26" frame
RockShox SID fork
Thomson Stem & post
WTB silverado
XTR groupset
XTR Brakes/Hope Race X2
XTR wheels/Hope SP3 XC6
Charge Splashback tyres 2.1f 1.8r
Crankbrothers candy pedals
Hope BB
Hope seatclamp
Giant carbon bars
Nuke proof grips
I am London based and still looking for a bike(s) to shoot with this build. If anyone has a bike they are happy to let me use then that's great and we can organise a meet.
Cheers!
Dave
