As the original product that launched Wolf Tooth Components, this 104 BCD chainring set the standard for modern 1x conversions—combining precise machining, proven wide\/narrow technology, and long-term durability in a lightweight package.\u003c\/p\u003e\n\n\u003cp\u003eAt the heart of every Wolf Tooth 104 BCD Chainring is the patented \u003cstrong\u003eDrop-Stop® wide\/narrow tooth profile\u003c\/strong\u003e. The wide tooth face maximizes contact on the drive side to better distribute pedaling load and extend wear life. The narrow tooth clears mud and debris efficiently, reducing friction and maintaining smooth drivetrain performance in rough conditions. The alternating wide\/narrow pattern dramatically improves chain retention and minimizes the risk of derailment.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with any \u003cstrong\u003e104 BCD crankset\u003c\/strong\u003e, these chainrings are designed for 1x9, 1x10, 1x11, and 1x12 drivetrains and meet the requirements for E-bike use. Riders using a 9-speed drivetrain should pair with a 10-speed chain for tighter engagement and improved chain security.\u003c\/p\u003e\n\n\u003ch3\u003eCompatibility \u0026amp; Installation Notes\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Any 104 BCD crankset.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Meter Compatibility:\u003c\/strong\u003e All sizes compatible with QUARQ power meters; 30T version is uniquely compatible in the 104 BCD category.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOlder Shimano 2x Cranksets:\u003c\/strong\u003e 32T size works with many XT, SLX, and Deore models.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e30T Chainring:\u003c\/strong\u003e Offset 2mm.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrivetrain Compatibility:\u003c\/strong\u003e 1x9, 1x10, 1x11, 1x12 (use 10-speed chain for 9-speed systems).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eChainring Bolt Requirements\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003e30T:\u003c\/strong\u003e Threaded; requires 7–10mm bolts (10mm recommended). 10mm required when used with 104 BCD bash ring.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e32T, 34T, 36T, 38T:\u003c\/strong\u003e Use 6mm 1x bolts (unless running a bash ring).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBash Ring Applications:\u003c\/strong\u003e 30T requires 10mm bolts; other sizes require 8mm bolts (stock 3x crankset bolt length).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWolf Tooth 104 BCD Chainrings Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBCD:\u003c\/strong\u003e 104mm.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Profile:\u003c\/strong\u003e Drop-Stop® wide\/narrow for maximum chain retention and mud shedding.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e CNC-machined 7075-T6 aluminum.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeights:\u003c\/strong\u003e 30T – 36g | 32T – 47g | 34T – 56g | 36T – 60g | 38T – 66g | 40T – 74g.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Made in the USA.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benifits\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProven 1x Conversion Platform:\u003c\/strong\u003e Modernizes double and triple cranksets with a clean single-ring setup.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnhanced Chain Security:\u003c\/strong\u003e Drop-Stop® technology reduces chain drops in aggressive riding.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLightweight Strength:\u003c\/strong\u003e 7075-T6 aluminum balances durability with minimal rotational weight.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBroad Compatibility:\u003c\/strong\u003e Works across multiple drivetrain speeds and popular crankset platforms.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch3\u003eFinal Take\u003c\/h3\u003e\n\u003cp\u003eThe Wolf Tooth 104 BCD Chainrings remain a benchmark for reliable 1x drivetrain performance.
