Wolf tooth was one of the first brands to see great potential in cyclocross single-speed bikes. Over time, with the help of new multi-speed kits, this trend has been carried through the gravel segment to the pure road category. So nowadays it's normal to see any kind of bike without a derailleur and with only one derailleur. For this type of application, there is this 110 BCD to 110 BCD spacing converter with a five-arm sleeve. It features the patented Drop Stop tooth design so there is no need for a chain guide. In the case of remodelling from 2x handles it is recommended to use screws with a length of at least 6mm. Drop-Stop A B is designed for 9,10,11 spd chains of all brands and for 12spd SramEagle, KMC, Connex and Wippermann, Sram Flattop AXS, Campagnolo Weight: 34t - 44g | 36t - 58g | 38t - 66g | 40t - 74g | 42t - 81g | 44t - 90g | 46t - 107g | 48t - 115g | 50t - 125g Material: 7075-T6 aluminium Made in USA
