In this article my friend Bicycleslut advises regular check of ones steed or things could get a bit 'emotional'. She knows her onions! I had an annoying noise from the bottom bracket area of Stig for a little while and couldn't work out what it was. Well, yesterday I solved it. 4 of the 5 bolts securing the chainring to the spider were finger tight or looser! That could have got really 'emotional' if I had been hooning it down a little hill.
Check your tackle riders! You know it makes sense.
