Where it fits for triathletes
The points below are our reading of the listed features, not test results.
- Training and sportive helmet. It is a vented road helmet, not an aero time trial lid, so it suits the long steady rides in a build.
- Fit check. Sizes and head shapes vary, so check the sizing on the product page before ordering.
- Price. At £139.99 it is £55.00 below the RRP.
