Rated 4.6 out of 5 by 7 reviewers.
Rated 4 out of 5 by Great product, easy to install. Pay attention to bolt length. Got the ISCG 05 version. Setup was kinda easy on my Giant Trance 27.5 with the exception for a little issue with the top bolt and lack of space. When I started to tighten the bolt I got the funny feeling that the bolt was way too long, even after using two spacers. It started to chip the maestro suspension part of the frame. Good thing I trusted my guts since it's really hard to see anything behind the mount. I did not loose more than a little paint so I guess the frame will be ok. Shorter bolt at the top now and good to go. Only used one set of spacers in the end. It's not making any noises yet and It's nice to know that the chain will stay on. 16 July 2014
Rated 3 out of 5 by Don't adjust it too high at the back or it will wear the slider. This fits easily and can be adjusted on the bike so you can rotate it adjust the tension it applies to the chain. Unlike a roller set-up you need to be weary of having it rotated too far round so it lifts the chain too much. I only rode 8 miles today of mixed AM/DH on m,y Meta SX and it has already gouged the guide such that it now runs noisily even at low tension. I'm not saying it's no good, it works fine, but some advice on set-up in the instructions would have been a helpful balance to their claims of zero noise, zero wear etc. Especially as I think it comes down to the fact that my 2x 10 set up with a 36 \sram rear cassette has such a large difference in cog sizes that usin g the larger cog sizes caused too much tension and hence the rapid wear. Just don't drink the marketing kool aid and you'll be fine- learn by my error... Given that it has two bolts I think they could make this to take a roller on the front bolt if people wanted the option. A friend has a rapid prototype machine so I might knock something up as a test. So don't forget, great piece of kit just don't over rotate it too far clockwise if using a big old rear cassette. 07 December 2013
Rated 5 out of 5 by Solid and pretty easy to fit It's a tough looking bit of kit, and reasonably light for what it does. I have a Commencal Meta AM and fitting this was trial and error. I bought the ISCG 05 version, but the offset from the mount to the front chainring must be a variable. It comes with 9 washers, three each of three different sizes, So I had to put 2, see how I fitted... Discovered I'd need 4 washers on each bolt. The chai guide is slippery plastic, there is no sprocket, good, as then it won't get jammed up with mud/grit. So getting it on was kinda messy, but it only took about 20 minutes. The box has the warranty conditions on it, they're a bit of a laugh, as they basically using the product will invalidate the warranty! 10 September 2013
Rated 5 out of 5 by Great 2x Chainguide Easy to install, just follow the Blackspire installation manual and do it all by eye. Comes with plenty of washers to space it correctly. I don't notice any drag on my pedals whatsoever, although I am reasonably fit. Have had no chain derails since I've brought it (mainly XC use so far) and slaps are kept to a silent on all but the bigger shocks. 21 August 2013
Rated 5 out of 5 by This is a good piece of kit I have used the stinger for years on a couple of different bikes, but this upgrade is the best investment I have made in evades to dual ring chain guides. Very quiet, well made. And made in Canada apparently. How can they charge less then the Taiwanese and Chinese made stuff? I would recommend this to anyone looking for a dual ring guide. 28 April 2013
Rated 5 out of 5 by Does what it should, and does it silently. Good days ride in mud had no adverse effects. Haven't "bashed" it hard yet, but looks sturdy enough... recommended piece of kit! 15 April 2013
Rated 5 out of 5 by Engineering at its best Love this bit of kit.. Hats off to the person who has designed it.. ease of installation is fantastic, on my Yeti I think it took all of 15 min.. has great adjustment to get settings just right.. and it is absoulutly silent. Does exactly what its ment to do... Thanks Black Spire 28 February 2013

Answer: 
yeh, it's 2xwhatever compatible- the only limits are on the ring sizes, so make sure you get the one with the correct max chainring size.

Answer: 
I use it on a 2x10 and its working great (although there was a lot of messing about with washers to get it in the correct position. On the basis that it works with a 2x10 it will be fine on a 2x9, the biggest issue will be the size of your largest front sprocket. I'm using a 38 tooth and its fine. I dont think it would work well with a front sprocket any larger than 40 tooth.
