Another upgrade are the high quality sealed bearings and single piece body which incorporates the freewheel body & pawl carrier in a single component, leading to a considerable reduction in weight. With 24 bladed aero spokes in the rear wheel using Fulcrum's patented 2:1 spoke ratio & 20 spokes on the front they look every bit as business-like as the more expensive models of Fulcrum wheel Weight: 1760g for the pair
