Buying Guide

Frame material and stiffness

Choose a bike with a welded steel or alloy frame rated for off-road use to resist flex on rocky terrain while staying repairable

Suspension type and travel

Prefer a front suspension fork with adequate travel for rocky trails to absorb impacts and keep the front wheel tracking

Brake system

Opt for dual disc brakes when possible for consistent stopping power and modulation on steep, uneven descents

Drivetrain range

A 21-speed drivetrain offers a wide gear spread for climbing and quick cadence changes on variable rocky routes

Tire clearance and wheel size

Look for frames and forks with enough clearance to run wider, grippier tires that improve traction and puncture resistance
