Hey Right, ive been putting of fixing my stock but now i need to. I snapped my mech hanger a few weeks ago.. so I had ago at making a tensioner that bolts onto the axel, now tension is dandy and that, BUT when i put pressure on the cranks ie gapping theres a slipping feeling/noise. its very scary and i dont have a clue what it is? its not the tenioner im pretty sure, although im going to whack a big fat roller on there instead of jockey wheel.. i can afford to buy a 74kingz tensioner, but ive herd mixed opinons on them, are they actually any good? Thanks
