Facebook Twitter LinkedIn Pinterest Bluesky Threads I have been told I need to replace my bottom bracket as the pedals and rings are wobbling around when I pedal. Where can I source a replacement? It’s a Specialized Sirrus Disc Hybrid 2017. Thanks for your help! by Strangely___Brown Bicycling Bike Bike Repair Biking Cycling Repair
VastAmoeba on December 2, 2023 9:12 am Bb shell is a very standard English thread, or bsa. Same thing. Bottom bracket is a Shimano square taper, bb-un65 or 300 or something like that. Takes the cranks off and measure from one square taper end to the other. That’s the length in mm you need to buy Any bike shop will have them. Or you can order from wiggle or ribble or whatever other silly online shop y’all Brits have.
