Yes - a new SRAM chain set and bottom bracket.
Anyone who's accompanied me on rides will at times have heard various "clicking" noises emanating from my crap FSA chain set on the Planet X. It tightens up on the non drive side with an inner bolt and an outer ring. However, despite being re-built twice with a new bottom bracket and 2 sets of replacement washers, it still clicks at times.
If it's tightened up too much that it ceases to click, then it creates too much friction. And if it's too loose, as well as the clicking, then you run the risk of the outer ring loosening off and falling out (as happened to Bruce on the March FNRttC to Southend).
I had been saying when it wears out, I'll replace it, but after rolling through Dunstable today heading home after about 30 miles, I noticed my LBS was open and I thought "Sod it", popped in, and grabbed a bargain.
Edit - and now it's fitted. Only 80g heavier than the carbon FSA and one little push sends it spinning around in glorious silence.
