We put the BH TT Carbon Evolution Red up against our Four Ride review.

  • First Ride

This is  BH’s pro level tri bike. A complex aero frame, Vision aero chainring, full carbon aerobars and deep Cole C85 clincher wheels round off an uncompromising package. The 120mm head tube allows for an ultra low tuck. First impressions are good – an efficient frame with slick SRAM Red shifting. The excellent Prologo Nago TTR saddle allows comfortable sustained power delivery.

  • Fast Ride

The character is hugely affected by the wheels. With tyres and tubes, they weigh 2.86kg, which dents acceleration. When cruising, the heavy rims help to maintain speed on the flat. While keen to spin fast in a straight line, they hesitate when cornering. The rigid chainset, huge bottom bracket and chainstays don’t waste watts and although the frame’s aero profiling makes it slippery, it acts like a sail in crosswinds.

  • Hilly Ride

You can achieve a good climbing position on the BH, but the combination of aerobar and stem places weight further forward than a road bike. The stiff frame suits powering over hills, but longer climbs are hampered by the heavy wheels. The cockpit gives great handling confidence. Vision’s aero levers perform well, and BH’s own-brand brake callipers stop well, even if their looks are at odds with such an aerodynamic bike.

  • Long Ride

Although unashamedly built for speed, the BH soaks up distances well. The bike can skip over larger bumps, but dulls high frequency road vibration to reduce fatigue. A degree of shock absorption from the aerobars helps over rougher surfaces, and the Prologo saddle, with a wide, non-slip nose, allows you to stay in a tuck for longer. The BH was well balanced and excelled on long, flat courses.
