Our opinion : chainring used in the World Cup by the UCI Massi professional mountain bike team on their XTR 9100 12-speed crankset!
Massi chainrings are manufactured using high-end processes and methods, from 7075 aluminium with T6 heat treatment and CNC machining. This material makes the chainrings lightweight, precise and wear-resistant. It features the Narrow-Wide tooth profile, a technology that ensures perfect chain retention on the chainring, thanks to the alternation of "narrow" and "wide" teeth. This chainring is compatible with Shimano 12-speed cranksets: XTR 9100, XT 8100, SLX 7100. The chainring is Direct-Mount type. A system that provides greater reliability and rigidity. This Massi chainring is an excellent alternative to replace worn Shimano chainrings (or to change gears). The quality/price/weight ratio is exceptional!
