Ground Breaking Cyclocross Bikes


Ground Breaking Carbon Cyclocross Bikes

The XLS is our full-carbon cyclocross bike offering a heady mix of performance, versatility and toughness. With its super-durable frame, the XLS meets the demands of CX racers and recreational riders alike. Hand-crafted from high-quality Toray T700 carbon fibre, the XLS is both strong and light, allowing you to fly up the ascents and out-sprint your competitors in the field.

An oversized carbon fork and headtube smooth out the roughest terrain, so you can enjoy improved tracking - at last, you can pick your line and stick to it! When it's time to dismount and 'shoulder' the bike over severe obstacles, the horizontal and comfortable profile top tube provides increased room within the front triangle.

Versatility is another area where the XLS shines. Fitted with knobblies, you have an off-road bike, but a quick swap to road slicks and suddenly you have a capable roadie, ideal for the club-run and commuting. Disc brakes deliver incredible stopping power in any weather conditions, so now the only question is, which colour are you going to get?


  • Hand-Crafted from Toray T700 Carbon - Strong & Durable
  • Choice Of Groupsets & Custom Wheels
  • Reliable & Consistent Disc Brake Performance
  • Lightweight For Incredible Speed & Climbing
  • Ultimate Versatility - Off-Road Or On
  • Drop Bar & Flat Bar Options Available

Serious Carbon CX Bike

Ready To Push Your Limits?

Tested & Raced Hard

In the hands of our team of sponsored CX racers, the XLS has seen more action and adverse weather conditions than any bicycle should have to endure. But the results speak for themselves... Time-and-again the XLS performs amazingly and boasts wins in countless events.

Cyclocross is hard on the bikes, which is why the XLS is so robust. This, coincidentally, makes it great for a range of other cycling duties, such touring, commuting and all-around winter adventure riding.

Smooth, Seamless Design

Precision Racing Carbon Fibre

Capable Carbon

The XLS is hand-crafted from high-quality Toray T700 carbon fibre, which is the ideal material because we've been able to shape and tease it to form a compliant frame that handles perfectly, whilst also providing amazing rigidity in all the right areas. The XLS' lightweight and efficient frame is perfect for putting down the power on muddy, bumpy climbs.

The XLS is built this way not because it's easy, but because it's the right material for the job!
