Got my trousers caught in the front freewheel, went to get it out and i was holding the chain up with my index finger, i rolled the bike back to get my trousers out and my finger went under the chain and round the sproket and the chain latched tight on my finger and i had to roll it all the way round 18 teeth lol. You could see the bone in my finger. I have been on anitbiotics and there is still puss coming so i have to go back to the doctors. I was off riding for about 3 weeks I wasn't able to bend my finger and put presure on the brake leaver.
