Where it fits for triathletes
The points below are our reading of the listed features, not test results.
- Upgrade, not a crankset. It fits an existing SRAM AXS crankset, so check your chainring and crankset against the list above.
- Dual-sided balance. Left and right power is reported separately, which is useful for pacing a long bike leg.
- Price. At £354.99 it is £86.01 below the RRP.
