asked by: a guest My existing bottom bracket is a 68mm x 113mm Tange with a FSA 22-34-44 square taper crankset. I would like to replace both of them with the Shimano Acera M361 22-32-42t Mountain Crankset with Chain Guard - Square Taper and the Shimano BB-UN55 bottom bracket. In the description for the Shimano crankset they recommend a 123mm spindle length. My old one was only 113mm. Should I order the new Shimano
anwered by: canteau Yes, you will need to replace the bottom bracket with a 123mm model.
