My 2013 Specialized S-Works Stumpjumper Carbon 29 SRAM XX1 build with some upgrades. The frame is size S = 15.5" and stock weight without pedal is 8.55 kgs.

With some following upgrades made it to 8.82 kgs with pedals:
- S-Works SL 100mm stem
- Tubeless conversion
- Hope F183mm and R160mm floating rotors
- Token CNC pedals

Stock:






After:




Next target to bring down the weight to 8.35 kgs with the arrival of S-Works Toupe saddle this coming Tuesday and also with tires change to Maxxis MaxxLite 29er.

Rocket! But it just does not look so good in a 15,5" frame size...
