Description

The Presto was developed through years of collaboration with elite MTB riders — Darren Berrecloth, Morgane Charre, Szymon Godziek, Rémi Thirion, Vincent Tupin and many more — resulting in a chain guide that is 30% stiffer than its predecessor at a lower weight. The backplate is CNC-machined from a single piece of 7075 T651 aluminium, with a thicker profile that achieves rigidity without adding material.

The bash guard uses an internal fin system to distribute impact energy across the structure rather than passing it to the frame. The smooth outer surface repels mud efficiently. In trail emergencies, the bash guard removes with a single wrench — no tools required beyond one key.

Mounts to the ISCG05 standard using 3 bolts. Crankset removal is required for installation — standard procedure for full chain guide systems of this type.

The upper guide link is rubber-secured, eliminating chain noise on rough terrain. The pulley runs on a sealed cartridge bearing. Guide plates are moulded from high-impact polyamide (PA6). All threaded inserts are metal — ensuring consistent service life under repeated assembly and disassembly.
