Submitted by Paul Cormier a Cross-Country Rider from Colorado Springs, CO

Date Reviewed: December 5, 1999

Strengths:    
Relatively Low Price
Easy to install
Good spring rate for 180+ pounders like me
Consistent rate at different temperatures


Weaknesses:    
Heavier than crappy elastomers it replaces


Bottom Line:   
These springs were absolutely necessary to bring the spring rate up to an acceptable level for a heavy, aggresive rider like myself. Before this spring I was flying over the handlebars on heinous dropoffs as the fork would completely compress. Not any more. Buy these if you are heavy and run the Manitou SXR. You won't regret it. -- PC

Strengths:    
Great Response over all things


Weaknesses:    
must use with fork that has damper, otherwise, pogo


Bottom Line:   
Great upgrade. Being a bit on the heavier side for cyclists (225), I would blow through the travel on my Judy on any big hit. Since it has been in the control has been great and I rarely bottom out. And since I am going to school in utah, the ride at moab is now sweeter and smoother. Yah baby yah

Strengths:    
Makes the Manitou X-vert shock feel better on large drops and on insane technical terrain.
Easy to install.


Weaknesses:    
Not very plush on medium size roots and rocks.


Bottom Line:   
I think this is a must do upgrade for the manitou shocks. I think the stock coil and MCU combo springs in these forks are great for easy to moderate trails, but when things go vertical, steep and rooty the stock springs are too soft. On difficult trails the braking action uses up over half the travel (even with proper sag is set up) thus when you need the travel to keep rolling over large roots you dont have enough left. The Dirtwork Dual Rate springs (medium) are plush in the first inch of travel so small fast bumps are well absorbed. The rest of the travel (3/4) is very firm compared to the stock manitou springs. This is great for downhill technical runs, but not so great on the easier roots or rocks as it is not very plush. I find that up hill technical climbs (which I love) are more difficult as the fork is not compliant on 3to6 roots any more as compared to the very plush stock springs. I have compensated on the easier trails by popping up my front end more instead of relying on the fork so much. I highly recommend this upgrade if you are into difficult terrain and want extra endo protection on rooty/bumpy downhill singletrack. I found that I had to change the oil from 5 (stock) to 10w for the spring to work well.

I just fitted the standard DW springs to my old Quadra 10s and now I have new forks! Twice the travel and much more feel. An excellent new lease of life to old tech.

Update to earlier post. Have received the dual spring kit for my X-Vert and love what it does for my fork performance. We had a little issue with compatability, but David at Dirt Works helped me out. I ride the firm kit, and it helps both the ride and control of my bike. 5 hot peppers for the upgrade.

Bottom Line:   
I didn't like the bone-jarring feel of the elastomers in the Judy T2 on downhill washboard. I was planning on upgrading with the Rockshox kit, but found the Dirtworks kit at 1/2 the price of Rockshox. Installed it in 20 minutes and the feel is noticably better. I'm riding downhill sections faster with the upgraded shock. Well worth the $34 (bikeworld.com).

Bottom Line:   
oooooh these are great. they make my shock oh so sensitive soaking up every little root so you can go so very fast and not worry about little obstacals... set them up w/ 10 w. oil in the tpc damper (a must over 5 w. as the spring makes the fork so much more active... open the damper up with 10 w.) this is for the tpc spring on 98 and newer forks you must get this spring it is wonderful and only 29.95.

Bottom Line:   
Did not like the response of my '97 Manitou FS (MCU/Spring) set-up, so I tried some Dirt Works springs (Phat Tire in Dallas, TX recommended firm, dual rate springs for my 205 - 210 weight). I really liked the way they changed the fork. A lot more lively and handled both small and big hits with ease. I just bought (installed yesterday) a '98 Manitou X-Vert for my Giant Full uspension frame, and ordered a new spring for that fork! 5 hot flaming chili peppers for the group out of Texas!

Bottom Line:   


The Dirtworks Springs brought a new life to my 97 Manitou SX Ti. Plush yet firm when it really counts. I guess that's the progressive spring feel. Spent $45 on the springs versus big bucks for a new fork, a good deal. I dock Dirtworks 1 chili on the install because I had to shave down the Dirtworks end pieces and file the springs some to get them to fit in the preload caps of the Manitou, but after a few minutes of preload adjustments I was rockin'.

Bottom Line:   


I instaled Dirt Works Dual Rate springs in my 98 Judy SL back in August. They are the best!! I've tried different combinations of the R.S. firm and med. springs, but I always had to use too much preload (3 full turns, I weigh 230lbs.). I dropped the Dirt Works Firm springs in and set my bike up with 1/2 turn of preload. The bike feels great!! It soaks up every thing I throw at it!! From small wash board to large hits, it makes my bike so plush and no hard bottoming out!!(I am getting full travel with these springs, the R.S. springs only gave me 75mm. All that preload I guess.) I have noticed that the bike bobs less on climbs with the Dirt Works springs than with the R.S. springs. Dirt Works has made a great fork even better!!! I wish they would make a spring for my rear shock.

I have used Dirt Works Suspension Stuff for over three years, and all of that time without any failures; just an enjoyable and enhanced ride. With full product support and personal committment, I think anyone looking to upgrade their suspension should look no further. As a racer of cross-country and downhill I have enjoyed using many different springs for a multitude of applications. Whether in a local state race, national, or World Chapionships, I knew I could always trust my Dirt Works.

These are GREAT! I got mine from Biek World for only $39. These make such an unbelievable difference to Judy XC. I put in the firm springs (I am 195#) and they are so supple. They really soak up the bumps better than the stock setup. I set the preload to 1/4 and am experimenting with the dampening cartridge but I love 'em just the way they are. Get some!
