Where it fits for triathletes
The points below are our reading of the listed features, not test results.
- Simple drivetrains. One ring removes the front derailleur, which suits a rider who wants fewer parts to set up and clean. Check your gear range against the courses you race.
- Short arms. The 160 mm option is relevant to riders choosing a shorter crank for a more open hip angle. We have not tested the crank.
- Price. At £499.99 it is £200.01 below the RRP.
