Ovalized chainrings for maximum performance
Introducing the new QX1 chainring, already XCM world champion under Christoph Sauser. The QX1 has an alternating wide/narrow tooth profile which prevents the chain from dropping in the worst conditions even without a chain guide.
Installation does not require disassembling the crankset from the bike, making ideal gear selection easier.
ROTOR REX 1.1 compatible, also with SRAM XX1 & Specialized cranks.
