Product description Key benefits Simplifies and lightens your drivetrain: ultralight square taper crankset (593.9 g) built for singlechainring (1x) setups, reducing weight and complexity while improving reliability on offroad and mixeduse bikes. Reduces chain drops and improves chain retention: the narrowwide single speed chainring is shaped to hold 10/11speed chains securely during rough riding. Durable, serviceable design: quality aluminum alloy construction with a frosted finish and reinforced threaded areas on the crank arm to resist wear and extend service life. What it is and why you need it A 104/64 BCD mountain bike square taper crankset designed for singlechainring use (1x). Ideal when you want a robust, lowmaintenance crank to pair with modern narrowwide chainrings and 10/11speed chains. Provides a simple, reliable solution for riders converting to or building a singlechainring drivetrain for trail, commuter, or gravel use. Specifications Crank type: Square taper mountain bike crankset BCD: 104mm (104/64 BCD specification as supplied) Crank arm length: 170 mm or 175 mm options Weight: 593.9 g Chainring options: 32T / 34T / 36T / 38T / 40T / 42T (single speed narrowwide teeth) Chain compatibility: compatible with 10speed and 11speed chains Material & finish: quality aluminum alloy with frosted surface; increased material density in threaded areas for improved durability Intended use: singlechainring drivetrains; not for multichainring (multispeed) crank applications Package contents: left and right MTB cranks, one narrowwide single speed chainring, screws Note: spindle/axle not included Performance and fit notes Narrowwide tooth profile improves chain retention without the need for a chain guide in many 1x setups. Designed to fit most mountain and road bikes that accept square taper cranks and a 104mm BCD chainring; check crank arm length and spindle compatibility with your bottom bracket before . Reinforced threaded sections help prevent crank pull and wear where pedals and bolts are torqued. Practical use scenarios Trail/Enduro 1x build: Convert a bike to a simplified 1x drivetrain for lighter weight and fewer dropped chains on technical singletrack. Pair with a compatible 10/11speed cassette and chain. Commuter or gravel bike upgrade: worn or heavy stock cranks with a lighter, durable square taper crankset and a narrowwide chainring for reliable daily use and easier maintenance. Bike restoration or custom build: Use as a direct replacement on older square taper bottom brackets when building or refurbishing a mountain or road bike that you want to keep running a single front chainring. What's included and important to check Included: left and right cranks, one 104mm BCD narrowwide chainring (selected tooth size), mounting screws. Not included: axle/spindle Before installing, verify bottom bracket spindle length and square taper standard compatibility with your frame and chainline requirements. This crankset is a practical, durable option when you want a lightweight, singlechainring drivetrain with improved chain retention and reinforced crank durability.
