Occasionally after a skid I notice that my pedals slip round with no cog movement, so like my legs spin maybe 1/4 rotation without any propulsion.
I am assuming something is loose rather than broke as it tends to be OK after an initial slip but yesterday it happened as I was moving off some lights and I almost came off.
Should I be looking at the BB & cranks or round the Lockring & cog.
I am fairly certain this must be a simple thing to solve but as I am not to savvy in bike tech its hard for me to visualise what is actually occurring.
Any help would be boss like, cos I looked like a right silly beggar (and almost died).
