Crewkerz WAW WPP RS


Sold out

  • Unique design!
- Brand new from Crewkerz, their latest stem concept designed in conjunction with WAW and WPP - the RS stem!
- Tested and used by top riders such as our very own Jack Carthy (using the 165mm stem).
- Designed with the intention of positioning your handlebars in the right area for most modern geometry bikes, but without the requirement for an extremely rolled forward bar angle.
- Forged construction means the ideal blend of strength to weight.
- 4 bolt split bar clamp helps keep your bars in place nice and securely.
- Sloped top of the stem helps give extra clearance at the steerer clamp area of the stem, although please note this stem requires the use of a flat cut steerer tube!
- Please note: for maximum support for your steerer, we highly recommend having 35-37mm of steerer tube available for the stem - this ensures that your steerer is supported by the 'ring' located on the top centre of the steerer clamp.
- Supplied top cap is flush with the top of the body, giving the stem a clean look.
- Top cap also comes with a steel M6 x 45 bolt.
- Supplied with a 20mm spacer for use on top of the stem, allowing you to experiment with your stem positioning/height before committing to trimming your steerer tube down.
- All versions are 15 rise (please note the graphic on the stem states 20).
- Weight - 135mm: 224.1g. 145mm: 226.2g. 155mm: 228.1g. 165mm: 228.5g. Top cap and bolt: 22.0g. Optional spacer: 5.5g.

Steerer clamp diameter: 1 1/8"
Bar clamp diameter: 31.8mm

Hi Paul - The black spacer shown is indeed a headset spacer, so theoretically it should work. The outer diameter is a touch smaller than most spacers, so if you were to use a different spacer you might need to machine it down. As you mentioned, you would simply use your standard headset top cap with it. The only thing to note is that you've got enough steerer tube to give good contact inside the stem as it has a large opening inside the steerer clamp area. Thanks, Mark
