    Helps stop the chain getting jammed. And stops it working with some cranksets.

    I think it stops the chain from dropping into and getting caught in the chainset. I had a chain drop down there and had to remove the chainset to get it out. This was after I removed that piece. Fortunately I had just left the car park and it was a short push back to the bike shop at Whinlatter.

    Thanks lads.
    Don't think I'll notice the weight reduction if I leave it off so it's going back. :D
