The new Direct Mount Retainer Ring by Hope Technologies is designed to eliminate the need of a chainguide while running a 1x drivetrain. This is accomplished by using the ingenious narrow/wide tooth profile. In other words, the alternating narrow/wide (or fat/skinny) teeth fit more directly into the narrow and wide spacing of a normal chain, "grabbing" the chain and holding it more firmly, even without the assistance of a clutch derailleur. The CNC machined 7075-T6 aluminum Retainer Ring not only holds perfect balance between lightweight and strength, but it completely obsoletes a front derailleur, eliminating irritating chain rub and drag. The hard anodized finishing make these insanely durable, keeping you turning over your 1x for years to come. The Retainer Ring is compatible with Hope direct mount cranks only and is available in a wide range of sizes from 28 to 34 tooth. Chainring bolts sold separately or with the Hope Direct mount spider.
