Ritchey Comp Press Fit Semi Integrated Headset

COMP level components are designed to bring competition worthy components down to a price that everyone can handle. You wont find carbon here, but you will find the kind of performance and reliability you expect from Ritchey.

S.H.I.S. Overview:

The 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 headset
  • Comp CroMo top bearing cover
  • Semi cartridge bearings
  • Supplied with Ritchey high quality alloy star nut and top cap
  • Black Finish
  • Fits tapered headtubes 1.1/8 - 1.5"
  • 109g

Headset Specs:

  • 11.3mm stack height
  • Upper S.H.I.S - ZS44/28.6
  • Lower S.H.I.S - ZS55/40
  • Upper Headtube OD/ID 50/44mm
  • Lower Headtube OD/ID - 61/55mm

Ritchey Headsets:

  • Our headsets dont always get the attention they deserve; beautiful handlebars and stems can be so distracting But this component is the interface between frame, fork and stem, and the basis for precision steering. Ritchey headsets are designed to take the abuse of bad roads and tough trails, while delivering smooth, reliable performance over the long haul.

Buy Ritchey Comp Press Fit Semi Integrated Headset from Chain Reaction Cycles, the World’s Largest Online Bike Store.

This item would not be compatible with a Kona Rove.

The Kona Rove uses an FSA ZST No.11AGY headset. This is a Giant specific standard which will be available from any Giant dealer.

Bearing replacement spare

I have a Ritchey WCS Carbon Press Fit headset in a Kinesis XCPro2 frame. The spec is for a 50mm OD Zero stack headtube for a straight 1 1/8"steerer. Could you let me know if you have a bearing for this and if so, the part number for the bearing replacement. The one I on your site is "sku233678". Would this be correct? Lastly, does this come with both top and bottom bearings?
Thanks in advance

Answers

Answer: 
You can remove and measure the existing bearing from the headset and measure them to check, but a standard 41.0mm bearing should be fine in most zero-stack assemblies. If you buy a full replacement headset it will be supplied with both cups and bearings, top cap and star nut.

Answers

Answer: 
The best way to identify your headset requirement is to measure the internal diameter of your headtube. 34mm is conventional style, 41mm is Cane Creek Integrated, 41.8mm is Campagnolo Integrated, and 44mm is Semi-Integrated (also known as Zero-Stack). I imagine the 2008 Storm was running an Integrated system, but can't be sure if it was a 41mm Cane Creek or 41.8mm Campagnolo style.
