Rocky Mountain Instinct Carbon 50 trail bike handles everything from all-day epics to technical descents
What Our Gearhead® Experts Are Saying:
"Pointed downhill on technical terrain, the Instinct stays composed without asking me to fight it through corners. Its steep seat tube keeps climbing efficient, and the suspension stays active enough on the way up that I'm not saving myself for the descent."
Why We Like It
Rocky Mountain overhauled the Instinct's geometry on this generation, slackening the head angle significantly from the previous version while steepening the seat tube to match. The result is a bike that handles more demanding terrain than the travel numbers suggest without giving up the climbing efficiency that makes a 140mm trail bike worth owning.
Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearhead® Experts are always here to help.
