Featuring a durable and hard-wearing Chromoly (CrMo) top bearing cover and an alloy top cap, for long-lasting performance you can count on. S.H.I.S. OverviewThe Standardized Headset Identification System (S.H.I.S.) creates a common language for describing modern bicycle headsets. The system provides comprehensive and scalable headset fitment information in a standardized format; making it easy to communicate headset requirements based on frame and fork interfaces.The system addresses the critical interface dimensions required to fit a fork to a frame, as well as bearing location/cup type. To determine fit, four dimensions are needed: (1) stem-clamp diameter of fork, (2) crown-race seat diameter of fork, (3) head-tube top inside diameter, and (4) head-tube bottom inside diameter. Bearing location and cup-type are identified as (a) external cup (EC), (b) semi-integrated or ZeroStack (ZS), or (c) integrated (IS).Bearing Location/Cup Types:EC (External Cup)Bearings contained within cups that are located outside of the frame.ZS (ZeroStack)Bearings contained within pressed-in cups where the cup and bearings rest inside the frame.IS (Integrated)Bearings that fit directly into a bonded or machined interface that is integrated into the frame.Features:A semi integrated press fit headsetComp Chromoly (CrMo) top bearing coverSemi cartridge bearingsSupplied with Ritchey high quality alloy star nut and top capBlack FinishSteerer Size: 1-1/8", 1-1/8"-1-1.5"Fits: 1 1/8" steerer tubeStack Height: 11.3mmUpper S.H.I.S: ZS44/28.6Lower S.H.I.S: ZS44/30Upper Headtube: 50/44mmLower Headtube: 50/44mmWeight: 109g (approx.)Buy Ritchey Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
