60mm Single Tii-on High Roller block

A high-performance block designed for high-stakes sailing.

This is the smallest block available on the market which features a high-load two-stage roller bearing system.  Roller(needle) bearings take the main loads of the sheave and offer great sheave rolling speeds at high loads.  The side load ball bearing cater for any off-centre loading and minimise friction further.

Easily unassembled and serviced to give longer lasting high performance.
