BBI-TT-BO12-POLY- (12-notch, 50.4mm, BBT-47 equivalent) This Nylon socket is the only tool you need to install or remove BBInfinite T47i and T47A modules and the DS stabilizer rings on all T47 variants we sell. This nylon socket is the same one that comes with every T47 we sell. NOTE: This tool only works on the DS stabilizer ring for T47E modules. If you have a T47E module, you will need to use our BBI-TT-BO15 or Park Tools BBT-69.4 equivalent to install the module itself as it uses a 16-notch, 44mm format. Use a 10mm hex socket or 16-notch, 44mm tool to drive the tool.
