The Story
The 2025 Trek Supercaliber SLR Gen 2 Frameset represents the next evolution in lightweight, race-ready cross-country performance. Built around a refined full OCLV Mountain Carbon layup, this frameset integrates Trek’s signature IsoStrut technology seamlessly into the top tube, delivering 80 mm of fully sealed, high-performance rear suspension that maintains pedaling efficiency while smoothing high-frequency chatter. The 29″ platform is optimized around progressive geometry—67.5° head tube, 71.5° effective seat tube, and a 465 mm reach—to blend responsive handling with stability on modern XC terrain. Internal routing for a dropper post, Boost 148 mm rear spacing, and flat mount disc brakes make it build-ready with today's component standards. The frame embodies a carbon-shaping philosophy that balances featherweight agility with race-caliber stiffness and durability.
