Frequently asked questions
Is the Epic or Supercaliber better for XC racing?
Both are proven cross-country race bikes. The Supercaliber's IsoStrut keeps weight to a minimum for pure racing; the Epic offers a touch more capability and a trail-ready EVO version. For marathon and mixed XC the Epic is more versatile; for flat-out racing the Supercaliber is razor-focused.
How much travel do these have?
Both are short-travel cross-country bikes built for efficiency, not big descents. They climb superbly and carry speed, but for rough, technical trails a trail bike with more travel suits better.
What should I check used?
On either, check the pivot bearings and rear unit for play and recent service. XC bikes are ridden hard and light, so inspect the frame carefully and run a stolen-bike check before paying.
