DNM Damping 3 System Mountain Bike Air Rear Shock Rebound/Lock Out/Air Pressure Adjustable AL 7005 Shark/AL 6061 Shock Body

Wow! I highly recommend for the price! I went from a non adjustable very squishy rear shock. So this was a big improvement! I am a pretty thick boy, on a pretty heavy e-bike. And it seams to be performing beautifully after putting hundreds of miles on it. I’ve only set the psi when I got it and haven’t had to add air since. It was very easy to install and didn’t seam to add any weight either!

For the price you cant go wrong!! Bought for my father tire ebike which is heavy as heck...stock rear shock was garbage this fit right in place absolutely no modifications needed.

This shock seems well built and has all of the features of a more expensive shock. I bought it to replace my fox float on my 2008 Cannondale lefty. I have not ridden with it yet on trails but from around the house after getting it to recommenced pressure it feels good. I gave it two stars for install. I have seen 5 min install videos for it and can believe it but with my old lefty it took trimming the inside bushings. Very slow process to not take too much off but it worked. Also I had to remove all the air from the shock to get it to line up with the upper frame. The hardware it came with was not even close to mine so I went with modifying my stock ones and good a quality fit. I will update my review after I test it completely. All and all good shock for the price if you are willing to overcome some obstacles if you don’t get lucky with a plug and play on your bike.

I needed to replace the rear shock on my 2013 Salsa Spearfish and found the DNM when searching Amazon for one of the $300 name-brand shocks. Given the price, I was a little worried about the durability and performance until I read some of the reviews. In the interest of science I decided to give it a test, and am I glad I did! The Salsa has always been a little soft in the back, sucking up power and making the bike less than effective as a cross-country racer. Higher pressure would help, but response suffered. The "pro-pedal" position had no effect. The DNM shock has transformed my bike and on the first ride with the recommended setup I beat my best time for our 10-mile XC circuit. Talk about impressed! The second loop was even faster. It has two chambers so compression and rebound can be finely tuned. There is also a rebound damping wheel and a lockout lever that actually works. I found the motion was so well controlled that I didn't need the lockout. Installation on the Salsa was difficult and required some tools that the average person might not have. Watch the video on Amazon as there are no instructions included with the shock! I needed to remove 2mm from the metal sleeves that insert through either end of the shock, and I needed to remove 1 mm from each of the plastic bushings that press over the end of the sleeve. They supply longer ones you can cut down if you have a steering column cutoff clamp but it seemed easier to take a little off the original parts using a bench grinder. The sleeve quickly heats up so I had to come up with a way to hold the part. After grinding I had to use a rat-tail file to clean up the bore and a mill file to clean up the ends. The bushings were easy to trim using the side of the grinding wheel. By the way, the video on Amazon that demonstrates modifications shows the metal sleeve being easily pushed out with fingers but I had to use a hammer and drift. All's well that ends well. Buy this shock if you need a replacement - you'll be glad you did.

A little background info- my bike is the amazing Gary Fisher Sugar 1, and I ride in the mountains of Arizona. When the stock shock (a Cane Creek Cloud Nine) began experiencing problems calling for a full factory rebuild, I did some research and discovered that I could buy this shock for less than the cost of that rebuild.Emboldened by Amazon's return policy, I took a chance and ordered one.First impression was that the shock looked great and felt like a quality piece of kit. Installation was nearly seamless- the eyelets on this shock measure 8mm, while the eyelets on the Cloud Nine were only 6mm. No problem- for another $5 I bought some 6x8 steel bushings, slid them into the DNM's eyelets, and mounted the shock easily.Time for a test ride! I took a gentle trail first, wanting to see if the bike felt different. After a bit of tuning on the rebound damper, the shock felt smooth and plush. Better than the aged CC shock which, in fairness, had lost all compression and rebound adjustments.For a tougher test, I headed for Granite Mountain. Bigger hits, rocky descents- the more technical the trail, the more impressed I became. This shock ate it all effortlessly. The lockout lever worked very well and helped reduce pedal bob on the steeper climbs to near zero.It's behavior and feel have impressed me for several weeks and a few hundred miles. All that's left is the test of time. The Cane Creek, after all, lasted over a decade and would still be a great shock had I paid to rebuild it. This DNM shock feels bulletproof. If I experience any problems, I'll be sure to update this review, as I continue to put miles on it.Edit 12/26/17- Two years in, and this shock is still going strong. I don’t use this bike as my daily choice, since I added a Pivot to my fleet, but the Sugar still gets plenty of use. The shock does not leak at all, despite the time and beatings it has taken. I would absolutely buy this shock again.
