Hello.Recently I got my hand on a Skyteam ST 125-y from 2005.The chain was snapped on it and i fixed it now it works pretty well.I was just wondering is there any possible way of finding out where to get the plastics from or what size would fit because I couldnt find any information on it and I cant measure it myself as the plastics are just too dead.Thanks

(I know people will comment that these bikes are bad but considering this is my first bike and I got it for free It seems to work pretty nicely)
