Jamie mcdonald Posted July 29, 2021 Report Share Posted July 29, 2021 I recently put some new cranks brothers stamp 2s on my trials bike and they were tight for a week of riding or so and it's almost like they just loosened in an hour today. I've tighten them back up now but I just found it unusual how they just loosened today. After a week of staying tight. Quote Link to comment Share on other sites More sharing options...
J.KYDD Posted July 31, 2021 Report Share Posted July 31, 2021 Pedal treads are designed to be kept tight by the normal rotation of peddling forwards. But with trials, there is so much slow speed hopping/shocking and quick back peddling so the pedals don't naturally stay tight so well. Same with bottom bracket cups. Before/after every 2-3 rides nip the pedals tight again to avoid ruining the threads in your cranks Quote Link to comment Share on other sites More sharing options...
