Some of our cranks currently use a wave washer and spindle spacers to adjust the bearing pre-load and account for tolerance differences in individual frames. If too many spacers are used the bearings can be over pre-loaded resulting in excess drag Our newer cranks use our APS system for preload which functions a bit differently. Refer to the owners manual to ensure that your cranks are installed properly. If you think they are installed correctly and you still have questions, contact your local Hive dealer.
