Simple works
Have this mounted on a Rocky Mountain Altitude 50 RSL with a Race Face bash guard. There was not room for the inner chain ring unless the BB spacer was positioned between the Stinger and the bearing cup. I suppose that's OK, but it makes the BB spacing 75.5mm and requires adjusting the Front Derailleur. But for that little oddity, the thing went on without a hitch. It is clever in its simplicity of operation; the chain simply climbs to the larger roller shoulder when you shift to the small ring and drops to the smaller one when you up-shift. It's not a case of never dropping a chain, but it happens a lot less often. Probably worth the weight increase if your trails deliver a beating like mine do.

A very effective chain retention device
I was getting tired of my chain derailing in the same rock garden. I run two front chainrings and did not want to spend a lot of money on a chain guide. I thought I would give this a try. Wow it really worked well and was very afordable. The Black Spire tensioner was very easy to install as well. It also made the shifting a lot faster front and rear. I am very happy with the product.

PROS: Lightweight, Attractive Design, Looks Cool, Easy To Install, Cheap Works Very Well, Durable

CONS: Limited Compatibility

BEST USES: Racing, Upgrade, Mountain Biking

Simplest chain guide out there
Kept dropping my chain ruining the flow of the ride. Picked up the Stinger for my Giant Reign. Easy to install, simple and does its job. Every now and than have to adjust it after it hits a boulder, but its held up great. No more chain slap or dropped chains, I can enjoy the downhill without interruption.

Needs redesigned
Installed on my 2010 GT Sanction 2x9. Went on fine but I had to use two BB spacers to keep the chain from rubbing on it which in turn made a more dramatic angle on my chain so I bought and replaced one spacer with a thinner spacer. Once that issue was bettered I found that to adjust tension other than the wheel adjustment you have to remove the crank every time, which could have easily been eliminated by supplying screws that have the hex screw on the other end just like the one on the wheel. DUH! Finally because of the design of the groove in the wheel which moves the chain over, if you back peddle more that half a turn the chain climbs to the big ring and jams. Making it an inch or so longer may solve that issue since it would move it away from the chain ring and less of a chance that the chain would move over. So it was totally useless on my bike, sending it back.

PROS: Durable, Attractive Design

CONS: Limited Compatibility, Heavy, Difficult To Install

BEST USES: Mountain Biking, Single Speed Only

Good Tensioner
Great product. I found it a little hard to set proper tension for a single speed set up. (I'm pretty sure that's not the intended use). It wants to turn as I tighten the bottom bracket. Tieing it to the chainstay helps, and then, slide the roller to fine tune.

PROS: Does not hang down far, High Quality, Durable

CONS: Tensioning for ss

Works great
Does what it is supposed to do. I Have a double chainring setup with saint m815 22x36 chainrings with a saint front derailleur. Really quiet on the uphills, haven't lost a chain yet on the downhills. Doesn't do much for the chainslap on the chainstays but I suppose that is inevitable with a dual ring setup...

Great For 2x10 set-up.
We have this on a Santa Cruz Bronson and a Santa Cruz Tallboy LT both 2 x 10 now. Works well so far. On some bikes the chain might rub slightly when your in the small chainring in front and big cog in rear. Once it is bolted in place I had to push it in about an 1/8". I pushed on the roller with my hand toward the chain stay just barely to get about a 1/16" clearance from the chain to the bracket. Use blue thread locker on the bolts, if they are not already coated, and you should be good to go.

PROS: Attractive Design, Durable, 1x And 2x Compatable, Easy To Install, Lightweight

Is this for a single or double chainring?
Randizle on May 24, 2016
I'm wondering how wide the pulley is. I have another product, designed for a double chainring, that is too wide to clear the inside of the crank, so it is useless. Pictures I've seen of the Stinger don't really show how wide the pulley is.

Will this work with a trek marlin 6?
