BHAerolight
BH's race bike that sets out to combine aero shaping and low weight: Kamm-tail tubes, an 'Air Bow' fork and seat stays that leave a wide gap to the wheels, a fully integrated cockpit and internal routing on a frame BH claims weighs 950 g. BH says it cuts drag by 15.9% (about 5 W) against the G8 it replaced. It is electronic-only, takes 32 mm tyres and is sold in four Shimano Di2 builds.

Our verdict
Overall
out of 100, average of 6 categories
A light, sharp-handling race bike that blends aero tube shapes with a 950 g frame and an integrated cockpit at a fair price. It is an older design with modest aero claims and 32 mm tyre clearance, and the press-fit bottom bracket and frame-specific cockpit, seatpost and hanger make it less easy to live with than simpler rivals.
