Leonardi Rosco Track HDM Chainguide

Chain guide ultra-light (35 g) for frames with High Direct Mount (HDM). The Leonardi Rosco Track HDM is highly adjustable, allowing even oval chainrings. With this chainguide, you will avoid that your chains go out and generate a greater damage or losing a race, adding just 35 grams.

Support in aluminium AL6061 and guide in Derlin. The Derlin is a high technology material developed by Dupont with a low friction coeficient, and a high wear resistance, so is better than aluminium or other plastics for this use.
