Date Reviewed: May 7, 2001
Favorite Trail:Deer Grove
Duration Product Used:Less than 1 month
Strengths:The shock rides real nice and looks impressive.
Weaknesses:I can't tell the diff from smart mode to manual. The rebound actions sticks somtimes and the shock blew oil all over my swing arm,brake and tire with less than 50 miles on it.(4th time out)
Similar Products Used:Fox RC
Bike Setup:Proflex 5000,Z3 bomber,XT drive,monkey light bars and ct2 post. Cancreek D-5 brakes.
Bottom Line:K2 is replacing my shock under warrenty with a nr-2. I hope it works the reviews where not assuring. Does anyone know a good aftermarket shock?

Submitted by James Bywater a Cross Country Rider from London, UK
Date Reviewed: April 22, 2001
Favorite Trail:Somewhere in Derbyshire...
Duration Product Used:More than 3 years
Purchased At:Noel Craft Cycles, Boston, Lincs
Strengths:Good all-round shock, very adjustable.
Weaknesses:I have had to replace twice due to oil leaks!
Similar Products Used:NR-2 on the front.
Bike Setup:Pro-Flex (K2) 957 Girvin Carbon Fork, mostly XT, hope 'fatso' hubs etc.
Bottom Line:It's good but the NR2 I have has outlasted it. Much more adjustable than the NR2 though. Might be better on a bike which has a bit more travel as the 3" on the proflex doesn't really use the shock to it's full ability.

Favorite Trail:That is personal
Duration Product Used:1 Year
Strengths:So far low maintenance. Compression is good.
Weaknesses:Controls are adequate, but could be more sensitive. Not user servicable
Similar Products Used:Stratos, fox,
Bike Setup:K2 5000, Marzocchi Z2 Bam, Mud, rocks and trail. Lizard Skin boot on the N4 from day one.
Bottom Line:I can recommend this shock now. The third one has been the charm(See my previous review from 1999). I did not have good luck with my first two. This one has not leaked any oil(I better run and check it after posting this ). I have had zero problems after more than 500 miles of nothing but dirt, rocks and one skunk. It has even cushioned my body on the Porcupine Rim Trail in Moab. I remember riding that trail a few years ago w/o any suspension. What a difference. PS I found a mechanic at the Kaibab(sp) bike shop in Moab who services this shock cheaper than K2 and offers some customizing options.

Duration Product Used:2 Years
Strengths:Great adjustability, and it takes BIG hits well. Also tracks nicely
Similar Products Used:NR-2, rst-22
Bike Setup:Proflex 4000se w/99 Judy XLC
Bottom Line:No problems. I've raced in it, i've rode some sick drop-offs, and i've ridden almost every day for the last 2 summers. I couldnt ask for more in a rear shock. My suggestion is, to buy a lizard skin for it. Grit gets on the shaft and i get worried... Otherwise its perfect the way it is. P.s.

Submitted by Craig a from Redmond, WA USA
Date Reviewed: April 23, 2000
Duration Product Used:1 Year
Bike Setup:'98 K2 4500 Carbon frame, Manitou X-Vert DC, NR4 rear shock, Hayes discs front and rear, Race Face and Shimano drivetrain, Easton carbon post and bar, Time pedals, Spin wheels....
Bottom Line:I've heard a lot of bad press concerning the NR-4... Mine has held up to a hell of a lot of thrashing and hasnt given me any trouble... I have had a lizard skin on it since day one, which is a good idea for anyone... The compression dampening is great, as are the bottom out bumpers, although I believe I have only hit them once or twice... I wish the rebound control was a little more effective, more towards the slower range, but that is a nit-pick at best....

Duration Product Used:1 Year
Strengths:pretty much everything about it
Weaknesses:Seems to squeak quite often
Similar Products Used:nothing... this is my first FS bike setup
Bike Setup:K2 proflex 5000
Bottom Line:I think this is an awesome shock for my needs... I've put some nasty abuse on this shock... no leaks yet, seems from the reviews that there are a lot of NR-4 lemons out there. Mine is great though, so since I have yet to come across problems it gets the best rating from me.

Bottom Line:Since purchasing my bike in 2/99, I have had two NR4s replaced. Blew the first one--go figure (I weigh 180 and do not ride real hard). Second one leaked a lot at the end opposite of the shaft. Oil was all over my rear swingarm, etc. You could even smell the oil after a ride. I hope my new one lasts a bit longer.

Submitted by Arjun a Cross-Country Rider from Vancouver, BC, Canada
Date Reviewed: October 2, 1999
Duration Product Used:
less than 1 month
Strengths:
*adjustable compression damping
*smooth
Weaknesses:
*adjustable rebound damping that isn't.
*poor quality control
*it sqeaks
Bike Setup:
K2 Proflex 4000SE
Bottom Line:I've had this bike for a week and a half-- I love it-- but I don't like the Noleen NR-4 rear shock. After my first ride on it, I noticed that paint was chipping off a part of the spring (see photo... I don't know if this form will accepot HTML or not). I didn't worry much about it since springs are made of very hard steel-- the piggyback couldn't wear through the spring.After my second ride a friend commented on the chipped paint. So I took a closer look. The spring had actually been wearing through the piggyback nitrogen unit! (2 images: image 1, image 2). This is obviously not a good thing! I wouldn't want a crack to form in the 200Psi nitrogen piggyback unit! This problem implies some very poor quality control on Noleen's part. Another issue that I have is that I can't adjust the rebound damping- as it is right now my shock has not much rebound damping, and I can't feel any difference in the damping whether the rebound is set to min or max.On the positive side, the shock is VERY smooth-- it rides quite plush, and the compression damping works very well (and is quite adjustable).

Compression, Rebound, Preload adjustments. This is my second NR-4. The first was not so good, but the second is great! I haven't touched the shock other than when I take my RTS frame apart and grease all moving parts. It has had a lot of dust, but still very smooth and quiet.

A little overdamped is correct, but it is plush. I like it.

Bottom Line:

I've already reviewed the shock, but I have to review the customer service. I was recently working on my shock when I accidentally let the nitrogen out. I figured it was gonna cost me. Noleen replaced my shock with the newest model for free, and in only three days! As for the newer model, it's even better than the old. Five chillis for the best customer service I've ever come across.

Bottom Line:

just bought a proflex 4000 xc, came standard w/ an nr-4. Travel is perfect for an xc, but handles downhill very nicely. I've heard a lot of stories of the nr-4 leaking from the seal... I've had mine for a month of hard riding almost every day and not a drop yet, just keep it adjusted for the conditions and take care of it. My only complaint is a slight squeaking noise on that only sounds on large compresions. It's not very loud soI don't notice when I'm riding, but when I'm tuning it up, it can get on my nerves. Anyone know how much longer it should take to fully brake in?

Bottom Line:

Bought a Jamis Dakar Team frame that had the Noleen NR - 4 as the rear shock. Had the bike built up and rode it..on my 4th ride.. I struck oil!!!!! Upon closer inspection...the NR - 4 in rear was the leaking oil heavily. Took it to an LBS and was told that it will take at least 3 - 4 weeks to get fixed from Noleen. Bummer!! I guess I have to ride my Hardtail.Shock was great while it worked. Going to buy a Cane Creek AD-10 to upgrade the Leaky Noleen NR-4.

Date Reviewed: September 8, 1998
Bottom Line:

Wow, the adjustments were great, and the shock suited me well after a few minutes of experimenting. I went Mountain Biking, for about 2hours and there was oil on my frame under the Noleen NR4 shock! I was assuming it was leaking. A brand new shock on a brand new bike leaked on the first ride! I liked the Noleen NR1 better, because it was very simple, and easy to use, with NO problems. Now, I'm going to have to go to the Bike Shop, to have them take a look. After the leaking, I had to put on a LOT of preload, and I'm wondering if the leaking changed the shock in some way. If you have any ideas, please email me!
I am very dissapointed in the shock. Instead of getting new ones or having service done, even if free, I would rather go back to the Noleen NR1, and have no problems.

I can't say that I have tried too many other shocks to compare this one to, but I've ridden a couple bikes equipped with Fox shocks (Kona and Heckler)and whether it was the bike design I dont know, but my KHS with the Noleen NR-4 was the plushest. Although my bike only gets 2.5 inches of travel, its very soft and responsive, and I've had it for almost 2 years and never had a problem with it.

Date Reviewed: March 21, 1998
Bottom Line:

i've recently replaced the nr-4 from noleen with a stratos shock. biiiiiiig difference. I recently found out that about once a year you have to send in all piggyback shocks, no matter what model, made by noleen, to the manufacturer somewhere in New Jersey (i think) so they can rebuild it. this is due to the fact that the air-pressure inside is susceptible to leaking. since this shock uses both air and oil for rebound at such high pressures (800+ psi), the seals have to be super tight, meaning stiction. this also makes the shock more susceptible to leaking air, as i found out cuz i lacked any rebound dampening. so now i have to send it back in before i can sell it. the fact that ONLY Noleen can pump air into this shock sucks, which means maintenance is virtually impossible. noleen should make their products a bit more user friendly. i had to find out the hard way that i was riding around a 2 pound elastomer, cuz it lacked rebound. this shock sucks. check out the helix expert from stratos, it won't disappoint.

Date Reviewed: December 13, 1997
Bottom Line:

I've recently just bought a frame used which was the atx 990 team edition from giant. i've never ridden and fs bike until this one. other times, i would ride my hardtail. the rockshox deluxe that came stock on this frame was blown by the previous owner, who used the frame for downhilling. she only weighs 120 lbs., which kinda makes me wonder about the quality in r/s rear shocks. anyways, she replaced it with this one and rode it for a year trouble free. now i'm bashing the frame around, and man, do i notice it. i ride over things the size of my head and it just sucks it all up. one note of concern was the lack of slower rebound dampening. although it's a gas to ride and it's range of adjustments suits my weight, 150 lbs., the ability for me to dial in a slower rebound stroke is important, and it comes up a bit short in this area. still, a bad ass shock. can't beat it's quality either.
