"really good product, took a bit of time to get the set up right, as you can see from the picture, its a somewhat unconventional design. You basically have to slice the frame in half to fit the chain but thats not a major job. out on the trails, it was just awesome, there is nothing like blasting past guys on £3000+ full suspension bikes on bikes like this! I even made a loss of £60 on the purchase price. Great kit!"
