High load blocks feature a stainless-steel sheave. This upgrade offers even faster rolling speeds, higher working loads and lower friction when compared to the standard acetal sheave. Ideal for use in higher loaded applications in dinghies, windsurfing, kitesurfing and anything else that runs smaller diameter lines.
Bearings – Dynamic Blocks feature twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.
