Have a less than 100 mile maybe sub 75 mile gxp bb with same usage SRAM omnium cranks. I was careful installing and as far as I know they are on correctly.
Last ride was a week Friday(or whichever one pissed it down) and it got soaked but I gave it a clean when I got home.
Just gone to take it out heard a swishing sound like a leaf was stuck on the tire rubbing the stays. But as far as I can work out it's coming from the interface between crank and bb at exactly the same point in each rotation of the cranks. I've run some kitchen towel between them in case it was loose dirt but it made no difference.
Is this just likely to be dirt? Do I need to service it after any rain? Have I bitten off more than I can chew?
I'm thinking of removing, cleaning and re installing but thought it well worth consulting the hive mind first. Any help appreciated.
