Posted on 17th, September 2015 about XCR BB Mount Chainguide by IainGil
I'm running a 1x9 with a 42t chainring. This product works perfectly. I have it up against the BB with spacers between it and the frame. This lines it up perfect. It's of really good quality. I'm very happy with it. It looks the business and works a dream. Next day delivery & sweets (thanks☺) Would definitely recommend this and will use Superstar again.
