it doesnt look too bad to be honest ,but if i had this bike these things would be my first upgrades, trialtech single speed conversion kit - £10 - tartybikes surly splined 18/19 sprocket- £22-tartybikes kmc kool chain-£14-tartybikes Gusset Bachelor-£14-tartybikes and i would also put a grind on the rear rim and buy some heatsink red pads,these pads are availiable from trials-uk. the rest of the bike looks ok and should be good for a while . steve
