Klein Mantra Race XL — Carbon URT Suspension — Shimano XTR / Hayes 22m - $675 (palo alto)

Klein Mantra Race XL — Carbon URT Suspension — Shimano XTR / Hayes 22mm - Vintage

Overview

The Klein Mantra Race is one of the most distinctive full‑suspension mountain bikes ever made. Featuring a unique carbon monocoque frame with Unified Rear Triangle (URT) suspension, it delivers excellent climbing efficiency and a one‑of‑a‑kind ride feel. This XL size example is equipped with Shimano XTR components, Manitou SX, FOX Float RL rear shock, and the original Hayes 22mm disc brakes — rare, valuable, and still working great. This bike is a bit of a unicorn. It's had some use, but pedals/shifts well and has decent bounce. We figure a new owner will want to make their own changes, so we didn't change the parts. The drivetrain has some use, and the shocks could probably use a refresh but they work.
