Overview

Geometry
When you really stop and think about it, mountain biking is kind of like cycling in its most primitive form. You're out in nature, where paved roads are a forgotten memory, so why go and muddy it all up with a bunch of stuff you don't need for a fun, relaxing ride? We hear you loud and clear, although we can't help ourselves but to over deliver in order to make sure that you have the best possible ride. And with durable, performance-driven components, reliable V-brakes, a bump absorbing suspension fork, and Sport Trail 650b Geometry that's sure to leave you feeling confident and inspired, the Hardrock V 650b is more than enough bike to get you out there riding dirty.
  • The frame is constructed from A1 Premium Aluminum in order to provide a lightweight, durable platform to support our acclaimed Sport Trail 650b Geometry. Combined, you get a bike that's efficient on climbs and eager on descents.
  • SR Suntour 650b fork features a coil spring that delivers 75mm of trail absorbing travel. 
  • A Shimano Tourney seven-speed rear derailleur gives you plenty of gear range to make climbing hills a breeze.
