Hey everyone. First time poster as you can all probably see. I bought a mod Saracen mad 2.zero and i haven't changed much at all as i've only had it for 3 weeks, i got it from a friend of mine for £50. All Ive done is tighten a few things etc, just performed some maintenance on it and put a 2 finger lever on the left for the back brake. I am having a problem though, when i pedal say after being on one wheel and just after i land it and start to pedal off, it pedals as if there is no chain attached, you know where there is no resistance but you don't go anywhere either, it feels like that but if it rolls along for a tiny bit the bike fixes its self and i can pedal again. Sometimes it happens while I'm on one tire and although i haven't been injured yet it can be VERY dangerous. Does anyone know what this is? Also the picture of my pedal: Do you think i need to purchase a new pair? As my feet frequently slip off it, or could it be my footwear? But i never had this problem on a mountain bike? And finally if you see the picture of my chain, it is sagging a bit and its a half link chain i think. So should i look into buying a new chain too?
Sorry for the essay it's just the questions that no one i know has the answers too. Any help towards becoming a full member would be appreciated too. If I'm allowed to ask?
Thanks
