Unphased and composed, it’s a hardtail 29er that puts full sus bikes to shame. Triple butted DN6 tubing is smooth and quiet. Oh, and it climbs so much better than you’d expect. The 77-degree seat tube puts you in an efficient climbing position to tractor up anything in front of you. Huge 29er x 2.8” tyre clearance for wide treads and mud clearing. The BSA 73mm Bottom Bracket ultra-durable, creak free and easily serviceable. Cables are routed externally for accessibility and ease of service.

GX Eagle

This GX groupset offers impressive performance with plenty of gears. Sharing many features with the higher end of the Eagle Ecosystem like the proven SRAM 1x-specific X-HORIZON™ body design, it can accommodate up to 10-52T cassettes. Eagle is a lighter, simpler, more durable, and easier to use drivetrain.

Reliable wide range 1x gearing

An 11-50 cassette provides a huge gearing range with SRAM’s top of the range aluminium 32 tooth crankset utilising DUB technology. Enough range to ensure you can fly downhill or comfortably spin up the steepest climbs.

G2 hydraulic brakes

The SRAM G2 delivers premium value braking without compromise. Powerful 4 piston callipers provide awesome single finger stopping power and reach adjust makes it easy to adjust your lever for maximum control. Think consistency, reliability and trust.

Our most aggressive mountain bike, the Hello Dave offers a different approach to mountain bike design, with a long and stable frame paired with a slack head angle, meaning when the going gets steep and fast, itll remain unphased and composed until you reach the bottom. The low and steep seat tube provides plenty of clearance between the rider and top tube, but with the dropper extended for the climbs that youll be in a good position to tractor up anything in front of you.



SRAM 12 speed GX Eagle groupset offers a huge range of gears for getting you up any gradient. A clutch derailleur and narrow wide chainring mean the chain will be noise free in rougher terrain. This great drivetrain has been paired with SRAM's Guide G2 R brakeset, top-flight 4 piston stopping power combined with great lever ergonomics.



WTB I30 wheels provide fast rolling confidence. Tubeless compatible, the 30mm internal width gives you a wider tyre profile, offering more grip and control



A Rockshox Pike fork with 150mm of suspension provides a supple yet supportive ride, while also being stiff enough to endure the rigors of the roughest terrain you have in mind. Featuring a tunable air spring and adjustable damping, this fork allows you to tailor it to your own preferences.
