Description

XC and Trail hardtail frameset that's ready to tackle some fast laps. Packed with all the latest frame specification choices the new Whippet is bang up to date. Lightweight, rigid, confidence inspiring and ready to fly, it's everything you'd expect form a thoroughbred racer.

Groupset: SRAM SX Eagle 12-speed performance from SRAM. Great chain retention, slick shifts and a huge gear spread courtesy of SRAM's 50t Eagle cassette. We've paired this great drivetrain with SRAM's Level brakeset, top-flight stopping power combined with great lever ergonomics.

Up front you'll find our favourite all-carbon rigid fork. Selcof make amazing carbon components and this fork is no exception. Stiff, rigid and featherlight it's perfect for those long drags and punchy technical climbs alike.

Upgrades : Our stock model is ready to rock out of the box, but dont miss our upgrade options to fine tune your purchase - remember - we build each bike individually for you - so take a chance to up spec your options or just take it as it comes. Whatever you do it will be amazing.

How do I unbox and set up my bike when it arrives

NOTE: Please make sure you check the size guide to order the correct size of this frame. If you are unsure please contact our Customer Service Department
