XHL BLOCK | Stu Bithell Review

Olympic silver medalist and Team Allen sailor, Stuart Bithell, reviews the Allen XHL blocks used on his International Moth in the video below.
The XHL range has been designed to deal with extremely high loads without compromising on low load dynamic performance. By combining the Allen patented dynamic bearing technology with a plain bearing peek washer we have created a bearing technology that has extreme dynamic performance even after being subject to static loads of up to 1250Kg. Coupled with CNC machined aluminium side cheeks and a precision turned stainless-steel sheave the range is perfect for use in vang cascades or halyard turning points where loads can be extremely high.
