DNM Mountain Bike Bicycle Air Rear Shock 165x41mm

This shock was surprisingly inexpensive and easy to set up. It came with a number of bushings to fit into my existing mountain bike frame to replace a coil shock. It had too much pressure in it when I got it to get the appropriate sag for my weight. Adjustment was easy but you need the right tools.There’s a small screw at the top front of the shock. Remove that completely. Attach a pin valve (the type you would use to inflate a basketball) into a high pressure shock pump. Note, you cannot use a regular bike floor pump. You have to drive the valve in as deep as it will go and push it hard to get it in there. Since I was releasing air pressure all I did was tap the pressure release on the pump to reduce the pressure in the shock. Jumped on the bike to check the sag I wanted and voila. Works great and has decent rebound.My take is the people complaining about the shock pressure etc don’t have the right tools to make the adjustment.

First of all it was really hard to get it to fit the bike because I had to sand down the inserts, then after taking it to the bike shop I discovered that to inflate it you need to use a needle valve. He did it but it lost pressure on the extraction even with a good high pressure pump. Mine simply could not hold a charge and I could barely get the valve into the fitting it was tighter then a ( you fill in the rest). I asked the bike guy about a shraeder adapter said it was impossible. Does any one else have any experience with one of those brass ones?

So far, I am not impressed with the shock. It is advertised as being adjustable, but has no way to adjust it. Where you would fill are normally, there is a set screw. The instructions say to use a ball pin, but that does not work. The shock is extremely stiff, being that it is shipped at around 150psi (according to limited info in instruction sheet). I have a Schrader valve ordered so that I can attempt to adjust the shock. I will write another review afterwards.....Fast forward a week: I installed a schrader valve ( Control Devices Brass Tank Valve, 1/8" NPT ) and the shock performs well , now that I can adjust pressure.

The shock was very easy to install. It is very quiet and dependable. It is sleek looking. It would be worth the price if it were three times the cost. I ride 3500 miles, plus, a year. It is super dependable and works great, right out of the box. Thank you very much for this super product.

This a budget air shock...it replaced a coil shock that was old and abused...it works on the larger ruts, rocks but doesn't compress on the little bumps but that's the limitation of any air shock or fork...I read people were having difficulty putting air in or out of this shock so I'll give a heads up. 1st remove the little shiny allen screw. Then use a socket to unscrew the hex bolt a half to a full turn. This makes it easy to insert the ball pin attached to your pump. If there is still alot of resistance loosen another half turn. The recommended air pressure for my weight (155-160) was 140psi. That was way to firm. I'm running 100psi right now and I may go lower to have more travel. Also, I'm using my wife's old hair tie to keep track of travel when I ride. This way I can adjust the pressure to the places that I ride.I had to expel all the air in the shock to install it as well as using my dremel to cut the silver bushings down to size. I had to add a washer on one end. With any retrofit there is going to be some kind of fabrication. If you aren't up for this take it to someone who is. I was surprised the it even came with bushings.I'm using this until I can spend more on another better shock with rebound. I've taken a couple rides on this shock and for what it is I am impressed but to me this isn't a long term solution.

Website shows port on this shock and to have to stab it with ball needle for air adjust absurd. If they provided a valve would make this shock more worthy.

The media could not be loaded.  Used this shock to replace the terrible coil shock that comes stock on the Burly Coho XC trailer. It’s awesome, fit exactly I was able to use the bushings that were on the Burly coil shock and they fit this air shock perfect. I did mount the shock upside down to clear the frame but it’s working great. I was able to dial in the pressure perfectly with my shock pump, but you need one of those needle style ends that they use for basketballs. So far so good. Just took the trailer around town with some gallons of water to simulate weight. Check out the slow motion video of it taking a curb, I may still need to dial in the pressure but I can’t wait to take this trailer out on some single track now. For the money you can’t beat this. I’ll update in a few months after a bikepacking trip and I really put it to the test.

Replaced a 1999 Rock Shox Sid dual air witH the dDNM Ao6. needed to swap the axle spacers from the sid but once I did it all fit perfect on my 1999 Specialized FSR expert. Test drive was flawless but haven't ridden a trail yet. Will update.
