Product DescriptionTKR9057B – Spindle Pin/Sleeve Set (revised, short/long, EB/NB48 2.1) These revised sleeves are required when using the TKR9141B -2mm spindles with CVA¡¯s and have been modified from the stock TKR9057 sleeves to provide clearance for the 15x21x4mm bearings. However, if you are running UNI¡¯s, the standard TKR9057 will work just fine. They are a direct replacement for TKR9057 going forward and are compatible with TKR9141 standard height spindles.
