My 7.8kg S-Works Crux Comfort Gravel Build | Lightweight Gravel Race Setup for Gravel Burn
Published at : 23 Dec 2025
Hope you enjoy this video! This is my custom build of the Specialized S-Works Crux, fine-tuned over the past few months in preparation for the first edition of the @Gravel_Burn 7-day gravel stage race in South Africa.
From chunky MTB tyres and wireless SRAM AXS blips to hollow bar ends and other smart Gravel Tech upgrades, this Crux build strikes the perfect balance between comfort, performance, and a sub-8 kg total weight.
Also I did attempt to fit a 2.1 (54) tyre on the back of the crux frame but the tolerance was too tight. So better off with the 50s.
