I've discovered cross by virtue of moving to where trails are 5 minutes from my door. But my Ridley is a little porky at 9kg.
The frame is one bought on Cyclescheme so cannot be sold, the rest of it is fair game although I think there is little room to manoeuvre.
Spec is pretty simple.
Ridley 2011 X-Bow frame & alloy steerer carbon fork
Record 11 running gear with Campag cantis & Extralite E-Bones ISIS cranks on FSA ISIS BB.
FIR SC170 rims on Record hubs with DT Comps & brass nips
Tufo 28mm Clincher Tubs
Deda Zero 100 Bars & Stem
Fizik Arione CX Carbon saddle on Time Carbon Post
The cranks, while light at 358g are limited to lead weight bottom brackets that wear out too quickly. So they will be replaced by a pair of Extralite E-Bones QRC cranks that I already have.
I've identified that the fork is a major culprit weighing in at almost 700g! I'm looking at the Kinesis Pure CX but have a dilemma. The Kinesis fork is 405mm from crown to dropout, but the existing fork is 396mm. How much will this affect the handling? At the moment it is 73.5 STA & 72 HTA.
Tyre choice is the other are I've identified for weight loss. I ride in an area where even in mid summer there can be mud so need a tyre that clears mud well.
