Description and materials
- Revolutionary, high-quality stem developed by French brand Crewkerz.
- Currently used by world class riders like Jack Carthy, Gilles Coustellier and Hannes Herrmann (check the Additional Information section to see which length each rider uses).
- The stem is forged in a single piece of aluminium alloy, so it doesn’t have any welds or any other weak points.
- Exclusive design, with a special curvature at the steerer clamp that increases strength and stiffness.
- Furthermore, it’s designed in such way that the bolt and top cap sit inside the stem.
- Also, the steerer clamp bolts are neatly integrated into the stem’s rounded edges, avoiding any possible damage when hitting this area.
- The handlebar clamp has a negative Offset, this means the handlebar no longer needs to be rolled forward so much, and therefore providing a much more comfortable riding position.
- Moreover, it’s 51mm wide so it allows for a more safe handlebar support, using 2 split clamps with 2 bolts each.
- Supplied with a CNC top cap, M6x45mm steel bolt and 20mm spacer to test different stem positions.
- Note: this stem requires the fork’s steerer tube to be flat cut. It’s recommended to have between 35 and 37mm of tube available for the stem to fit securely.

- Forks with a flat-cut steerer tube.

| Patxi V. el dÃa 2021-06-28 | Mira que llevo años probando potencias, pero esta me ha sorprendido. Llevo la 155-20. Se ve muy robusta y la posición sobre la bici es diferente, merece la pena. |
