This lightweight upper guide mounts to ISCG-05 tabs for a really secure fit and can be adjusted to accommodate chainrings from 26 to 38t. Fitting is easy and MRP provide enough spacers to fettle the spacing to your heart’s content.
A rubber coating on the inside of the guide means no chain rattle or rub if things are slightly misaligned. It was only when conditions were really grotty that we heard any noise from the V3, and even then it was minimal. We haven’t had a single dropped chain since fitting it, which is great considering its minimal 41g weight, and there’s an even lighter carbon-backed version for 165$ if you’re a real weight weenie.
