Where it fits for triathletes
The points below are our reading of the listed features, not test results.
- Hookless rims. The maximum pressure is 72 psi, so check your wheel maker’s tyre pressure limit before fitting.
- Race day. A light cotton casing is a race-day tyre. A tougher tyre will suit daily miles better, and we have not tested wear.
- Price. At £72.99 it is £12.00 below the RRP.
