A carbon rigid fork that weighs 563 grams bare and clears a 32 inch wheel. Swapping it in for a suspension fork takes 4 lb 6 oz off the front of the bike. The carbon layup also soaks up the fine buzz from gravel and hardpack, so it rides less harsh than an aluminum rigid fork.
On a 4130 Trail
The RockShox Psylo Silver RC that comes on the 4130 Trail is 550mm axle to crown. This fork is 495mm, which is 55mm shorter, so the bike steers quicker and sits lower. The 4130 Trail runs 180mm rotors and this fork is post mount for 160mm, so you need a +20mm post mount adaptor (not included) to keep the 180mm rotor.
Mounts
Three cargo mounts on each leg plus rack mounts for a front rack or lowriders. It has no fender mounts. If you need fenders, the steel rigid fork has them.
