If you’re looking for one of the lightest and fastest XC race bikes available, this is it.

This is a custom-built 2025 Trek Supercaliber SLR Gen 2 in M/L. It was built with premium components from the ground up and weighs just 22.8 lbs with Maxxis Rekon Race 2.4 tires.

The bike is less than a year old, has never been crashed, and is in outstanding condition. No scratches, no damage, and everything functions exactly as it should. I am the original owner.

Build Highlights

• Trek Supercaliber SLR Gen 2 frame (M/L) • RockShox SID SL Ultimate fork • RockShox IsoStrut rear suspension • SRAM XX SL AXS Transmission drivetrain • SRAM XX SL crankset • SRAM XX cassette • SRAM Level Ultimate brakes • ENVE M5 carbon wheelset • ENVE carbon stem • Mount Zoom carbon handlebars • ONE carbon seatpost • Syncros Belcarra carbon-railed saddle • Maxxis Rekon Race 29x2.4 tires • Carbon bottle cage

Approximate weight is 22.8 lbs as pictured. Swapping to Aspen race tires brings it very close to 22 lbs.

This bike climbs incredibly well while remaining surprisingly capable on technical terrain. It has been meticulously maintained and is ready to race, train, or enjoy long mountain rides.

Pedals are not included.

If you’re familiar with high-end XC bikes, you know this isn’t a stock build. The frame, drivetrain, and ENVE wheelset alone make this a truly exceptional race bike.

Happy to answer any questions or provide additional photos.

Reason for selling: I signed up for LoToJa this year and all of my training time has shifted to the road. As much as I love this bike, it simply isn’t getting ridden and I’d rather see it go to someone who will enjoy it than have it sit in my garage.

NO TRADES! Bike is a 100% custom build, not something purchased at the store. It would cost $12.5-$14k to do this again today.
