Strengths:    Light?

Weaknesses:    Air valve degrades with use. Every time I've put air in it, it leaks out faster. Serious design flaw.

Bottom Line:   
Aired this shock up to 190 (my current weight). Rode for 1 hour, lost 100 psi. Aired it up again, rode 1 hr, lost 150 psi. Aired up again, rode 20 minutes, lost 170 psi. Aired up again, would not hold air as it all leaks out the valve where it swivels. Stay away from this shock. I'm moving to a coil assisted shock now.

Rated lowest because well, its not value if it does not work. After four rides, this shock is a complete failure. I don't want SRAM to fix it, I don't trust the product at this point.

Strengths:    great product when it works

Weaknesses:    leaks like crazy, difficulty getting satisfactory warranty service

Bottom Line:   
If you can get this shock to work, it's great. 6 months after I purchased the bike, the shock bottomed out completely. It took me a while to figure out what the problem was. When I finally got a clue, SRAM sent replacement parts but would not replace the whole shock. Before I even got out of the driveway, the shock bottomed out again. This time SRAM refurbished it. 15 minutes into the first technical ride, the valve stem snapped completely off. I'm 5'8, 140 and an amature rider. SRAM, this is your last chance to make it right.

Strengths:    -Great damping
-Supple yet doesn't bob like my old MC3
-Like the sag measurements on the arm

Weaknesses:    -Air leaks
-Bad valve
-Air leaks

Bottom Line:   
Look, I have had this shock for approx 6 weeks. After the first week I noticed that it was leaking air. Called RS and they told me to bring it in to my LBS so that the valve assembly could be replaced. Got it a week later. Had a race today and what shock started to bottom out (basically lost 60psi!) around halfway through the race. After the race I approached the SRAM tent and told them what happened. Some tech just tried to tighten the air valve assembly and said to call SRAM. He said I might have to have it rebuilt. OMG, after 6 weeks. I am giving SRAM one more shot to get this right. If not, then I will take the loss and switch to Fox or a Cloud 9.
C'MON SRAM lets get this right.

Strengths:    Works well once dialed in.

Weaknesses:    Along with the other negative reviews, these shocks (2.1,,4.2) originally came with a faulty or loose air valve. Rockshox has fixed this issue now and will provide either a repair kit or a new shock. This should no longer be a negative since RS has fixed the issue, all you have to do is call them.

Bottom Line:   
These shocks work well once the air valve is repaired. I do prefer the lockout levers on the higher models.

Strengths:    The shock rebounds nicely, and with the gate full on it allows for stiff climbs.

Weaknesses:    The air stem valve is very awkward, the rebound adjustment knob is virtually impossible to adjust. My finger barely fits in the area provided. The gate adjustment is sketchy. You feel a difference only full on, or full off. Looses 30-50 lbs of air pressure after a day of hard riding.

Bottom Line:   
If you plan on riding hard, and weigh over 190lbs, don't get this shock. For a light weekend warrior the shock will suit fine.

Strengths:    Good feel, compression and rebound works well

Weaknesses:    Unreliable, leaks air, swivel head shock pump connection work itself loose and leaks, came with little oil

Bottom Line:   
Ive had this shock for 4 months now. I bought it as an upgrade from my 2006 Fox Float R. Installation and initial setup was very easy, aside from the rebound knob being very awkward to access, but it worked. After 3 short XC rides to run the shock in it developed a slow leak, losing about 10psi over 2 hours of XC riding. From their on it got progressively worse to the point where i would have to stop riding every 20min to pump it up again, otherwise it felt the bike felt heavy and sluggish. Rather than take up a warranty claim i took it to my local Rockshox rebuilder and upon opening up the shock it was found to have next to no oil left and the seals had therefore degraded and needed replacing. After it was fixed it then went another 12 weeks with no problems. In fact it ran like a dream. Then the swivel head that the pump connects to began to come lose and leaked so bad it wouldnt hold any air at all. That was fixed, but then the slow leak began again, and after a few rides it was losing 30psi every 45min. Ive now given up on this shock and on rockshox, and replaced it. I should have listened to my piers and stuck with another higher quality brand.....

Strengths:    Strong, relieble, works fine on any trail, eats small bumps with floodgate almost fully activated.

Weaknesses:    Rebound adjustment affects floodgate settings a little bit, but it's not a bad thing. U just have to turn shock right.

Bottom Line:   
This shock lacks quick adjustment lever (Monarch 4.1). In all other cases its a good shock for the money.

What is the current replacement shock for a '08 RS Monarch 3.1?

OE on my old Iron Horse. 7.5" x 2". No platform. No lockout. Just air and rebound damping. I never had trouble with mine until just lately when the air leaked out of it. Then I saw the reviews and everyone said they leaked so I am a little leery of bothering with a rebuild kit. What is the ... Read More »

Monarch 3.1 wont hold air

I have a KHS 555 with a Monarch 3.1. The bike rides fine, but the shock loses presure overnight (goes from 145 to 100 or so), and I have to air it up nearly every ride. THis is a huge pain in the butt. I have sent in the shock for service (and a new valve which appears to be a common issue) and ... Read More »
