Couronne Wolftooth 104 BCD – WolfTooth Components

104 BCD is the most common bolt pattern on double and triple cranksets and happens to be the first product ever made my Wolf Tooth Components. The Drop-Stop® tooth design is the best performing and longest lasting wide/narrow Couronnes on the market. Fits any 104 BCD crankset Drop-Stop technology. On Wolf Tooth’s patented wide/narrow Couronne, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves Couronne life. The narrow side allows clearance pour mud and debris which reduces friction. Alternating wide/narrow tooth pattern prevents chain derailment   CompatibilityFits any 104 BCD crankset Couronne Bolts: All tooth sizes require 1x bolts that are 6mm long with exception to 30t rings which are threaded and require bolts that are 7-10mm long. Wolf Tooth carries both sizes in a variety of colors 104 x 30t – use 10mm bolts 104 x 32t, 34t, 36t, 38t use 6mm bolts.  If using a bashring you will need 8mm bolts (most stock bolts on 3x cranksets are 8mm) 32t 104 BCD Couronnes work on many older 2x Pédaliers Shimanoet (XT, SLX, or Deore) The 30t x 104BCD Couronne is the only available ring pour the QUARQTM power meter Drivetrains: 1×9, 1×10, 1×11 and 1×12 drivetrains Compatible with all 10-, 11-, and 12-speed chains except Shimano 12-speed chains Shimano 12-speed chains require the use of our Shimano 12-speed specific Couronnes If using a 9-speed drivetrain use a 10-speed chain. It fits tighter pour better chain retention   RecommendationsIf you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck.   Related Products 64 BCD Couronne if you need something smaller than a 30t  104 BCD Stainless Steel Couronnes Couronne bolts 104 BCD bashring   Tech SpecsWeight: 30t • 36g | 32 • 47g | 34t • 56g | 36t • 60g | 38t • 66g Material: 7075-T6 aluminum Made in the USA WARNING Handling this product will expose you to chemicals, including lead, known to the State of California to cause cancer and birth defects or other reproductive harm.
