Marin Larkspur CS1 bottom bracket part number
Hi, I have a Marin Larkspur CS1 (2013 I think, though may be 2012), getting a cracking sound from around the bottom bracket, so I think it may on the way out, though there is no play in the cranks yet. Does anyone know the part number for this bottom bracket? I've googled but I can only find it is a 'sealed bottom bracket', but it looks like there are a few different types. I'd like to change it myself as I prefer to maintain my own bikes (and the rest of the family's!) if possible. Cheers.
