Rated 5 out of 5 by Fitted this product to my bike with no problems,tried other makes like mrp and e13 but had clearance issues i needed a chain device to fit to my bb mount and this one went straight on and tried and tested and everything still is fine,looks the part too very impressed with blackspire products and chain reaction for fast delivery. 11 April 2012
Rated 5 out of 5 by Great chaindevice. I have to run a bottom-bracket mounted guide and had all sorts of chainline issues trying to fit a Superstar, Truvativ and all sorts of other combinations. This one fitted straight on and because of the way its cut out in the back it meant that I didn't have to file down the granny ring tabs on my Saints, just incase I ever want to run 2x9 again. Its nicely adjustable, it looks great and it can be set up to run with virtually no noise at all. Excellent and under-rated product. 31 August 2011
Rated 5 out of 5 by jajaja... this is the best chainguide ever... at first, it touched with the screw in the cranks but then nothing else... just 1 or 2 times going out and the noise stopped... you need at least a 38t ring at least so it gets protected by hte upper protection... In white it is completely white... everything except the wheel... Its just lovely:D 07 February 2009
Rated 5 out of 5 by such a good chain guide:D i had a roox roller coaster (like 3x more expensive) and wasn't as good as the blackspire:D really worth buying it:D 23 July 2008
Rated 5 out of 5 by Would this chainring and chain device fit on a 2006 specializedd big hit with a race face evolve crank ??? If so which one would i require ?? 03 January 2008
Rated 5 out of 5 by Excellent product, silent, light, looks good. CRC's delivery was lightning fast as always. One thing to note is that the chainring ratings on these device are just that, chainRING ratings. This device is rated up to a 40t, and it does protect a 40t, but once the chain is on, it exceeds the bashring and all those links are unprotected. If you wish to protect your chain as well as the ring make sure the maximum rating is 2t above your ring, I run a 38t on this now and that's the biggest I can go without the chain being unprotected. This isn't CRC's fault as the description is striaght off the blackspire website. But perhaps CRC should put a note by these devices descriptions? 25 February 2007
