I was browsing price point and saw a Blackspire Stinger chainguide for $22.00 that mounts to the bottom bracket. It mounts a chainguide just under the chainring. I'm setting up a new AM HT as a 1x9. I have a short cage XT derailer already and was gonna go with the bashguard/Ngear jump stop setup but saw this. Plus I think it will handle my jumping alot better and look clean. Anyone use this Guide before? http://www.pricepoint.com/detail.htm?stylePkey=15288&style_id=075 BLAST6

I have one set up 2x9, bb mount type. to have it set up 1x9 I would recommend their inner ring guide to go with it. It basically makes a "chain-sandwich" between the inner guide and the bash ring, stinger keeps the chain tensioned.

An e-type is recommended because the stinger is goes between the frame and the bb, and is roughly 2.5mm thick so you need to accommodate for that thickness. If using a hollowtech II crankset (or similar) then you can simply adjust the spacers to make it fit. That said I am running an old school octa-link bb thats not e-type and it works fine but I will be changing it out in the near future

This thing didn't work out too well for me with my particular crankset (older-style RaceFace XC).....the gap between the middle-chainring and the blackguard was still just wide enough that my chain would fall off and get stuck in there.........
