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 from a thoroughbred racer.

Groupset: SRAM GX 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 Guide G2 brakeset, pro-level 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.

Sizing Guide

Rider HeightSuggested Frame Size
5′3″ to 5′7″ (160cm-170cm)Small / 15.5"
5′6″ to 5′10″ (168cm-178cm)Medium / 17.5"

6′1″ to 6′4″ (185cm- 193cm)X-Large / 20.5"

Sizing Notes

All frame size recommendations are approximate. A good fit will also depend on the correct choice of stem length, correct bike set-up for the rider and riding style.

Correct frame size choice can vary greatly with riders' torso length. If you have longer legs and a shorter torso, go for a slightly shorter stem. If you think you are borderline between sizes, and you have longer legs and a shorter torso, go for the smaller frame size. If you have shorter legs and a longer torso, go for the larger frame size to get the extra top tube length.

As the frame sizes increase, so does the length of the head tube. If you are inflexible or perhaps have a history of back problems, consider going for a larger frame size. This will increase the relative height of the handlebars making the position less “extreme”. The larger frame will also have a longer top tube, so you’ll need to compensate for this with a shorter stem.
