Wanted: Stem, bars, chainring and sprocket

fc9k I'll still running the cheapest shittiest cranks ever, £15 new off ebay. They say DOTEK on the back, and came with a single ring and a shitty metal trouserguard ring on the outside. Anything I should be aware of in terms of failures? At the moment I'm loathe to change them since they're not too precious and hence are handy to sling against lamposts when locking up to save the paintwork on the frame.

I've got dotek on my fixed. to be honest they are damn sight prettier than the rpm's i have on my other bike. I matched them to a cheap 80s sugino chainring so look decent enough from a distance.

depends on your budget but i'd ride them till they die!
