On-One's Whippet SRAM SX is made for going fast... lightning fast. On-One's taken all of their carbon frame knowhow and distilled it into a lightweight, hardtail frame with progressive geometry. It's perfect as a rigid bike for the purist, and simply flies down the trails with a set of suspension forks on the front.

  • SRAM SX Eagle 12-speed groupset
  • Selcof Carbon Fork

Description

The XC and Trail hardtail frameset are 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. On-One has paired this great drivetrain with SRAM's level brakeset, top-flight stopping power combined with great lever ergonomics.

Up front you'll find On-One's 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: The stock model is ready to rock out of the box, but dont miss the upgrade options to fine tune your purchase - remember - we build each bike individually for you - so take the chance to up spec your options or just take it as it comes. Whatever you do it will be amazing.

Pedals not included? Why not?

Pedal choice is a personal thing. Most higher end bikes are expected to be ridden with clipless pedals. These are matched to cleats on the underside of your cycling shoes. There are a few standards of these, and most cyclists tend to stick with one standard across all their bikes. So, you don't need to buy multiple pairs of shoes! That's why Planet X don't sell bikes with pedals included. If you wish to add pedals to your order, simply select an option from the drop-down menu.

NOTE: Please make sure you check the size guide to order the correct size of this frame.

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.
