BH is the largest cycling company in Spain, where it enjoys a history of supplying bikes to professional teams, including the current Ag2r squad. At the heart of this bike, intended for both time trials and triathlon, is a frame made from high modulus carbon fibre that’s shaped to bring the trailing edge of the front tyre close to the down-tube, with the rear wheel cutting into the seat tube’s profile.  


In line with other high-end time trial frames, the fork’s teardrop section sweeps backwards and the control cables exit through the top-tube to reduce drag. The rearward facing dropouts add stiffness and don’t present a problem for fast wheel changing or dirty hands once the drill flicks the rear mech fully inwards prior to fitting the back wheel into the frame.

The lack of a reversible seatpost could be seen as a setback for triathletes, who like to pitch forward in the saddle in order to aid the transition from running to cycling, but in practice the fixed 75 degree seat angle is a happy medium.

The gear and finishing kit package includes a Shimano Ultegra SL rear mech and FSA front mech, FSA Team Issue carbon crank arms connected to an aluminium spider that carries a 39/53-tooth chainring combination, a 12-23 10-speed cassette that’s perfect even on moderate climbs in a time trial, and Vision Tech brake levers.

There are two sizes of seat-tube available, MT (600mm) and LT (650mm), with a common top-tube length of 54cm. As the Vision Tech TriMax Plus tribar (worth £225) is non-adjustable it’s important to select one with the right stem length – thankfully there are three to choose from: 9cm, 10cm and 11cm, which we recommend for riders over 6ft to avoid brushing their knees on the armrests.  


The LT20’s low overall weight of 8.3kg, slippery frame and high levels of stability give this bike a broader appeal than most, and the Cosmic Carbon SL wheels alone retail for £900, making it a value package.
