BH Aerolight Disc cheats wind for triathletes, adds disc brakes & hidden cables

Tips & Reviews

BH announced the 2020 Aerolight Disc, a new triathlon and TT bike. With full cockpit and cable integration, it has no exposed wires – adding to the aerodynamic prowess of Kamm-Tail tubing. In addition, it joins other brands with new standards and trends like disc brakes, 12mm thru axles, and 28mm tire clearance.Advertisements

While BH makes a wide variety of bikes, they’ve had a lengthy presence in the triathlon scene. The addition of the 2020 Aerolight Disc gets them on board with the latest tech movements, while making continued aerodynamic refinements.

The new frame uses Toray T800 and T500 fibers and Hollow Core Internal Moulding technology, said to optimize weight and stiffness. BH also opted for a BB386 EVO bottom bracket shell, with the intention of keeping pedaling efficiency at a high level.

Flat-mount disc brakes and 12mm thru axles are stock front and rear – with a unique twist. The thru axles have a small lever that slides out of the center to facilitate tightening and loosening.

BH opts for the Vision ACR system, keeping cables and Di2 wires tidy up front.

All models opt for Shimano Di2 shifting, with cranks and wheels as the main spec differences between tiers.

Kamm tail tubing shapes are combined with a unique seat stay arrangement. Not only is there clearance for 28mm tires, but they’re actually spec’ed from the factory.

Four sizes are available, all using 700c wheels.
