Helix Race Carbon Cranks are a milestone in carbon crank design. Featuring highly optimized carbon crank arms and lightweight 30mm aluminum spindle, these cranks dramatically reduce weight while maintaining incredible strength. Weighing in at just 335g (170mm), they exceed ASTM 4 test standards, making them equally at home on everything from Aggressive Trail and All Mountain rigs to feather-weight XC Race builds. The Helix Race Carbon utilizes an 8-bolt chainring interface (chainring sold separately), with a twist. By incorporating a unique four-bolt locking mechanism in their Helix Race 8-Bolt Chainring interface, weight is further reduced while improving longevity (standard 8-bolt chainrings also compatible). Available in popular crank lengths of 165mm, 170mm, and 175mm, Helix Race Carbon cranks come equipped with molded crank boots, an APS adjuster, captive pedal washers, and a convenient self-extractor system, ensuring simple installation and maintenance. If you're looking for the highest strength-to-weight ratio in MTB cranks, you just found it! 55mm Chainline with Helix 8-Bolt Chainrings (chainring sold separate) 171mm Q-Factor Helix Race Carbon Cranks represent the pinnacle of carbon crank design, robust enough for All-Mountain applications yet lighter than many road cranks Industry leading strength-to-weight - ASTM 4 approved 8-Bolt standard chainring interface Designed for 55mm chainline with use of Helix Race 8-Bolt Chainring (sold separate) Crankset includes: molded crank boots, APS adjuster, and self-extractor system Lightweight and rugged 30mm aluminum spindle Item Specifications BB Included No Chainline/Hub Compatibility 141/148 Boost Hubs Chainring BCD Direct Mount SRAM 8-Bolt Color Carbon Crank Intended Use Mountain Crank Length (mm) 175 Defined Color Carbon Drivetrain Speeds 11 Drivetrain Speeds 12 Number of Chainrings No Rings Included Pedal Spindle 9/16" e*thirteen Helix Race Carbon Crankset Crankset EAN: 4711280345670

Wolf Tooth T47 Internal bottom Brackets are engineered to be smooth, durable, lightweight, fast, and user-serviceable. Their ground-up design features custom bearings, seals, bushings, and cups, which eliminate creaking and balance best-in-class weather sealing with optimized bearing radial compression, alignment, and preload for low drag. The Wolf Tooth Bottom Bracket bearings feature custom designed balls and races that are made from a hardened chrome bearing steel which has a higher surface hardness than stainless to improve the durability, reduce spinning resistance, and noise. An ACOSUR ZNA coating has also been applied to the race to provide corrosion resistance that is equal to or better than stainless steel after a 500-hour saltwater test. Bearing material paired with an extensive sealing system and the elimination of metal-on-metal contact means Wolf Tooth Bottom Brackets deliver superior performance in all conditions. Wolf Tooth bottom brackets are designed, engineered, machined and assembled in-house at Wolf Tooth HQ in Minnesota, USA. Bottom bracket also includeds: (2) 2.5mm shell spacers, (2) 0.5mm spindle spacers, (2) 1mm spindle spacers, (1) 3mm spindle spacer, (1) 5mm spindle spacer, and (1) 7.5mm spindle spacer Best-in-class sealing achieved by grouping a spindle o-ring, seals on the bearing/bushing gutter, inner and outer low contact bearing seals, shell o-rings, and a labyrinth-style end cap to ensure your bottom bracket will run smoothly no matter what conditions you ride in Custom bushings separate the bearing inner race and crank spindle to eliminate metal-on-metal contact, the leading cause of bottom bracket creaks, while also aiding in bearing longevity with an interface to the bearing gutter seal for maximum weatherproofing Custom AlSl 52100 chrome bearing steel hardened to Rc 61-66 reduces friction for smooth pedaling with ZNA corrosion-resistant coating Adjustable-width design allows the same shell to be used for 85.5mm - 92mm width T47 Internal Bottom Brackets Easy installation and removal using a standard spline 52-16 bottom bracket tool (Sold separately) Item Specifications BB Shell Width (mm) 86 BB Shell Width (mm) 92 BB/Frame Interface T47 Bottom Bracket Shell I.D. 47 Defined Color Black Spindle Interface Type SRAM DUB Weight 96 Wolf Tooth T47 Internal Bottom Brackets Bottom Brackets UPC: 810159401425
