    Not universally compatible

    Unfortunately it seems that unless you have a Shimano XT or XTR cassette (or other cassette that breaksdown into more component parts) you cannot use this expansion sprocket. Despite chatting with the guys at Tredz I could not do as they suggested and loose the 13t sprocket and re-assemble the modified cassette even if I wanted to loose that useful sprocket. the middle group of sprockets were riveted together so I was not able do as the instructions suggested. Pity, I might upgrade the cassette and have another go sometime.

    10/10

    Bought for my wife's bike, which is now 1x10. Fitted easily and so far has performed brilliantly. Came with longer b limit bolt, with a hex head, so no more rounded out philips screws.

    Great value expansion sprocket

    Very impressed with the quality of this so far. Was easy to install and has given me that little extra for steeper hills - recommended!
