I was having trouble downshifting gears i was really having to stamp on it to get it to go down a gear. So i took it to the shop and had the guy look over it he said he would have to order a clutch cable in but he tightened it up to make it easier for me to change gears till the cable came in. (Keep in mind this is the shop that kept my bike for 4 weeks waiting for a Master brake cylinder so i have been getting sick of their service or lack of they seem like amatures). I then went for a ride over to my friends place which is 20 mins away and just as i was about to turn into the bottom of his street i pulled in the clutch to go down and snap they cable was gone. I have already given the guy at the bike shop $40 because he had to order the clutch cable but to me if he has tightened it up and 20 mins later it snaps should he be to blame? And can you just put any clutch cable into any bike or does it have to be one from the company that made the bike?
