Boardman ATT 9.8 LTD Mens TT Bike 2021 - XS, S, M, L Frames

The 2021 ATT 9.8 Ltd uses a high modulus C10 Carbon frame and fork resulting from years of extensive research and development to deliver outstanding aerodynamic performance. Deep, box-section chainstays ensure excellent power transfer, meaning none of your effort is wasted. A stunning 9.8 Ltd paint scheme in metallic black and brushed titanium give the bike the looks to match its speed. Bottle cage mounts on the top tube for a bento box give an extra option for storing food or spares on longer rides.

A carbon, aero-profile seatpost with 4 saddle clamp positions and a highly adjustable Zipp Vuka Alumina cockpit means it is super easy to get your body into an aerodynamic and efficient position. When 80% of the overall drag comes from the rider themselves, this is crucially important. The Fizik Mistica saddle allows for a low, aggressive position with plenty of comfort too.

Shimano’s reliable 105 derailleurs combine with Dura Ace bar-end shifters giving precise shifting, even in the midst of an all-out effort, and 25mm Vittoria Zaffiro Slick tyres offer a great blend of comfort, speed and grip.

This high-performing aerodymanic frame and great quality specification makes the ATT 9.8 Ltd the perfect entry point into dedicated Time Trial and Triathlon machines.

Boardman ATT 9.8 LTD specifics:

  • Frame: Highly aerodynamic high modulus C10 Carbon frame and fork
  • Versatility: Wide range of positional adjustment to optimise efficiency
  • Gears: Quality Shimano Dura Ace / 105 shifting
