On-One Hello Dave SRAM GX Mountain Bike

The Hello Dave is a bit of an anomaly. Not many hardtail mountain bikes enable you to ride anything you dare point your front wheel down. With a long and low frame, aggressive angles and a 150mm fork, you wont ever feel held back by high speeds, big jumps or steep chutes again.

UDH: accepts SRAM Transmission
SRAM GX Eagle 12 Speed Groupset
SRAM G2 R Hydraulic Brakes
WTB I30 29er Wheels

Frame

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.

Groupset

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.
