Oval 104 BCD Chainrings

Compatibility These rings fit any 104 BCD crankset Designed to meet the requirements for E-bike use Chainring bolts: DropStop B options use 10mm bolts DropStop ST (only avialable in 34t) option use 6mm bolts, unless using a Bash ring Wolf Tooth&';s patented wide/narrow tooth profile for the ultimate chain retention and mud shedding ability For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle) If using a 9-speed drivetrain use a 10-speed chain (shifts and works well on a 9-speed drivetrain and fits the ring tighter for better chain retention) Quarq power meter compatible with size 34t. Filing is required for 32t fitment onto some older Quarq Power meters. No modifications are required for the DUB Quarq Power meter. Ovality of 10% and timing of 112Adeg after TDC (top dead center) Maximum diameter is that of a chainring 2t bigger than the size you order (so be sure there is adequate chainstay clearance.) Recommendations If 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. Recommend the use of a clutch style rear derailleur for the best chain security.
