Wolf Tooth 130 Bcd

5 bolt 130 bcd round crankset for cyclocross, gravel or road.CompatibilityCompatible with 5-arm 130 BCD crankset.NOT COMPATIBLE with Shimano DA 9000 / Ultegra 6800 cranks.NOT COMPATIBLE with Campy CX10/11.SRAM Exogram cranks with inserted nut must use the original fifth bolt + spacer(s).The Force CX1 bolt features a fifth bolt with 1 specific shoulder.Drop-Stop B chain compatibility:For all SRAM Eagle, SRAM Road and Transmission (T-Type) flattop chains, 9, 10 and 11-speed chains or 12-speed KMC, Connex, Wippermann, Campagnolo.NOT COMPATIBLE with Shimano HG+ 12-speed chains.Important note on the 38-tooth single chainring:The chain may slightly contact the spider arm when using the 38T chainring.We recommend filing a small chamfer on the spider arm, but you can also install it and let the chain do the work.This is only a problem with the 38T as the 130 BCD was designed for the smaller 39T ring.The original 2x bolts will not work.You will need Wolf Tooth´s 6mm bolts, which are optimised for single ring mounting.This 1x chainring can be mounted in the inner or outer chainring position of a double crankset, but cannot be used in a 2x configuration.Chainline:The most common mounting is in the outer ring position due to chainstay clearance.The centre line of the ring is ~2 mm from the mounting face of the ring, so they are generally located approximately 2 mm closer to the frame than the original large ring (depends on the original ring).Use Drop-Stop B for all SRAM Eagle, SRAM Road and Transmission (T-type) Flattop chains, 9, 10 and 11-speed chains or KMC, Connex, Wippermann, Campagnolo 12-speed chains.Technical specifications.Weight:38t - 52g | 40t - 60g | 42t - 62g | 44t - 79g | 52t - 132gMaterial:7075-T6 aluminiumMade in the USAColour:Black.
