On Monday I found an FSA powerbox alloy crankset and power meter online for £60 ex-display, confirmed they had it, ordered it with next day delivery, hadn't turned up by lunchtime today so emailed them to find out what was going on, apparently they don't have it anymore. Annoying, but worse I had ordered a new set of chainrings to go with it as they only had 53/39s on it which is way to high a gearing for me. The chainrings arrived this morning. Also ordered batteries and a new bottom bracket for it (BB386evo, which I already have fitted, but figured a new one wouldn't hurt).
This is all to replace the power meter I have fitted which doesn't take a charge anymore. So having got so close and been foiled I've ordered an alternative Powerbox carbon crankset which Windwave (FSA distributors) had for a significant discount. It's 48/32 so nice and low gearing and with sending the chainrings back tomorrow it's only a bit more than I was in for before. I'm deluding myself over sunk costs but despite knowing this I find it easy to talk myself into these things.
