The high speed bobbin was designed to make it easier to spin finer yarns, by introducing higher ratios. Its ratios are: 6.5:1, 9.5:1 and 15:1 This high speed bobbin is clear lacquered to match the finish of the S10, S10DT and S51, S51DT. This bobbin has been carefully crafted to make spinning at high speeds a breeze. The bobbin has a sheave with three settings on one end to obtain three different spinning speeds.
The high speed bobbin will fit on all current and discontinued Louet wheels EXCEPT: S40, S45, Victoria, S87, S90.
