Rotor REX 2.1 MTB Crankset Single X1 Qring

SKU N/A Categories , ,

ROTOR Bike Components has developed a specific oversized-axle crankset for multiple BB systems (BB30, BBRight & classic BSA), based on its successful 3D crank, Being both lighter and stiffer than the titanium 3D crank, this is a lightweight, full aluminium, purebred performance crank weighing just 527g for 170 mm / (w/o BB, chain rings or spacers). -This crank is manufactured using an improved version of our proprietary Trinity Drilling System technology during manufacture. Due to the larger axle-crank contact area of a BB30 crank, all three holes can be drilled from the axle side of the crank arm, allowing for further optimization of wall thicknesses, improving both the weight and the weight-rigidity ratio of the crank arm. -Certified to EN 14766 standard. Impressive specific stiffness figure. The REX2.1 crankset improves upon the stiffness to weight ratio of our 3D crankset, which is well known in the market for its extreme rigidity. -Precision bearing preload adjustability achieved with a simple to use compression ring with locknut. -Compatible with nearly every bottom bracket standard in the market: BB30 frames (68 mm bottom bracket width). Classic BSA threaded frames for BB24 cranks, by means of our BSA30 BB. -Available in 170, 172.5 & 175mm lengths. -Manufactured by forge and CNC machining -Only compatible with 76 BCD Q-Rings and Round chainrings INCLUDE QRINGS X2 YOU CHOOSE THE SIZES; Outer – 40, 39, 38, 36t Inner – 27, 26, 25, 22t DELIVERED TIME FOR THESE PRODUCT IS 4 WEEKS
