E Thirteen TRS Race Carbon Gen4 CranksetFeaturing a trail-rated, compacted carbon fibre crankarm construction, this mountain bike (MTB) crankset offers a fantastic balance of stiffness and durability while also keeping weight to a minimum. e.thirteen has also kitted out its World-Cup DH-rated layup and construction with an additional 3K carbon finish that’s added to the front and rear faces for greater impact resistance. This makes it more than ready for tackling the most demanding of terrain conditions as you weave from trail to trail.Trail-Ready MTB Crankset with Adjustable ChainlineIn contrast to e.thirteen’s Gen3 carbon cranks, the Q Factor, overall profile, and volume of this Gen4 model has been greatly reduced. The spindle has been moved to the non-drive side for easier chainguide setup and drivetrain maintenance. Its adjustable chainline accommodates non-Boost, Boost, and Super Boost setups. Finally, all cranks now include an 8mm self-extractor.Features: Crankarm Material: Carbon Fibre with 3K Carbon finish Use: MTB Compatible Chainring: SL Chainring (-8mm offset) Number of Chainrings: 1 Compatibility: All frames with 73mm BB Shell Spindle: Width: 73mm; Diameter: 30mm, Interface P3 Connect Q Factor: 178.2mm Included: Crankset, APS Adjuster, Installation Tools, Crank Boots (x2), Sticker, User Manual Bottom Bracket Included: No, available separately Chainring Included: No, available separatelyManufacturer’s Part Number: E13CR2010 Black 165 x 73mm E13CR2011 Black 170 x 73mm E13CR2012 Black 175 x 73mmBuy E Thirteen Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
