Description and materials
- New edition of the top-of-the-range Clean Trials Pro stem, now featuring a 20º angle instead of the 24º used in the previous version.
- Retains the exclusive Clean design and technical features of the Pro range, incorporating updated geometry and a redesigned top cap system.
- The handlebar clamp features two independent plates and 4 M6x16 mm bolts, fitted from the bottom upwards to prevent chest injuries. This design makes handlebar installation easier and ensures secure clamping during use.
- New system with a separate top cap, included with the stem, which rests on a flat surface at the top of the stem base.
- The stem body is manufactured from a single piece of moulded 6061-T6 aluminium with high dimensional precision, optimising strength and stiffness.
- Exclusive Clean design, specifically developed for the demands of bike trials.
- The steerer tube clamp retains its angled design, with a base height of 34 mm up to the top cap contact surface.
- For correct installation, approximately 29-30 mm of the fork steerer tube must extend into the stem base.
- The centre of the upper stem clamp bolt is positioned at a height of 25 mm, so using a fork steerer tube shorter than this measurement is not recommended.
- Available in 3 different lengths, all with a 20º angle: 135 mm x 20º, 145 mm x 20º and 155 mm x 20º.
- Supplied with the top cap and 7 M6 steel bolts: 4 M6x16 mm bolts for the handlebar clamps, 2 M6x25 mm bolts for the steerer tube clamp and 1 M6x35 mm bolt for the top cap.
