BoardmanATT 9.8 Ltd
The last listed version of Boardman's more affordable time trial and triathlon bike, built on a C10 carbon frame and sold through Halfords. It uses rim brakes, with the rear brake hidden, a PF30 bottom bracket and a four-position carbon seatpost that moves the seat angle between 76 and 79 degrees. That covers both UCI time trials and steeper triathlon positions.

Our verdict
Overall
out of 100, average of 6 categories
A used-market bargain for riders who want a carbon TT bike for club time trials or a first triathlon. The four-position seatpost covers UCI and steeper tri positions, and the parts are standard and easy to replace. Expect rim brakes, mechanical 105 and basic wheels and basebar that are worth upgrading.

Good to know
Design
The C10 frame mixes Toray T1000 and T800 fibres and uses deep box-section chainstays and a PF30 bottom bracket for stiffness.
SourceAerodynamics
The rear brake is hidden from the airflow. Boardman developed the ATT with CFD, wind-tunnel and real-world testing, and Cycling Weekly reports it uses Boardman's 'Aerodynamic Surface Trip' texture to delay flow separation.
SourceFit
The four-position seatpost moves the effective seat angle between 76 and 79 degrees, so one frame covers UCI-regulated time trials and non-drafting triathlon positions.
SourceRacing
Cycling Weekly found the short wheelbase and 72-degree head angle (on the XXS test bike) made it quick on flat, straight courses but less settled on technical descents.
SourceHistory
In 2017 the ATT frame was sold separately for £1,399 and the ATT 9.2 complete bike cost £2,299. Cycling Weekly rated it 9/10 for its stiffness and value, but said the stock wheels and basebar needed upgrading.
SourceVersions
The 2021 ATT 9.8 Ltd is the newest ATT on Boardman's site; the brand's online catalogue has not been updated past its 2021-2022 range, so the model is treated here as discontinued.
