Suntour Durolux and Carbon Fork - Eurobike 2011

Sep 7, 2011

Suntour Eurobike 2011

SR Suntour's Durolux fork impressed us when we reviewed the 2011 offering, but they've stepped up to the plate to sort out the fork's few minor shortcomings for '12. This should put the competitively priced Durolux firmly on everyone's radar, especially those who don't want to drop two months salary on a fork, but still want reliability and performance.

The Durolux is available in a few different flavours, but the updated RC2 TAD (Travel Adjust and Damping) equipped model that can be adjusted in 40mm increments, from 120 - 160mm or 140 - 180mm with or without, will make a lot of sense for those who want to get to the top of the mountain under their own power. There is also a non-TAD version that makes use of the same new RC2 damper who's travel you can adjust by moving spacers within the spring leg. The 35mm stanchioned fork is designed for all-mountain or Mega Avalanche riding, and can be had with either a tapered, 1-1/8" or full length 1.5" steerer.

SR Suntour Durolux details:
• Intended use: All-mountain/Mega avalanche
• Travel: 140 - 180mm or 120 - 160mm (external travel adjust), 160 - 180mm (internal adjust)
• Adjustable low speed compression, high speed compression, rebound
• Air sprung (more progressive spring rate for 2012)
• 35mm stanchion tubes
• Magnesium lowers w/ 20mm QLOC thru-axle
• Available with a tapered steerer, 1-1/8" or full length 1.5"

The Durolux is available in a few different flavours, but the updated RC2 TAD (Travel Adjust and Damping) equipped model that can be adjusted in 40mm increments, from 120 - 160mm or 140 - 180mm, will make a lot of sense for those who prefer to earn their turns. While still available with a bar mounted remote, SR Suntour's new crown mounted PUSH button (above left) will keep the bar mounted clutter to a minimum. Simply push the button and lean on the fork to lower it by 40mm. The button works by transferring air from one side of the cartridge to another, then shutting off the passage. The system is simple inside, requiring minimal extra seals. We got to play with the a PUSH button operated TAD Durolux at the show and the design couldn't be easier to use in practice.

Even bigger news in our eyes is the addition of high speed compression control via an anodized aluminum dial at the top of the fork, giving the rider the ability to tune both high and low speed compression separately, as well as rebound and air spring pressure. The dials also get much stronger detents for 2012, remedying one of our few complaints with the 2011 model.

Inside the Durolux you'll find a completely reworked damping cartridge (left) that includes an interesting compression blow off design. The adjustment needle that controls the amount of oil flow is spring loaded, allowing the needle to self adjust to the force of the impact to prevent spikes in the fork's compression. SR Suntour have put a lot of time into sorting out the proper spring rate for the needle to ensure that it opens with the correct amount of force. We'll be putting time on the updated internals in the near future to see how the design functions on the trail. The new cartridge is also 80 grams lighter than last year's version.

Non-TAD equipped Durolux forks from last year required you to push a roll pin out in order to reposition the top out spring and change its travel. While it was an easy process, we're happy to see that SR Suntour have made the switch to slotted spacers (above right) that can be quickly removed and repositioned. This lets you choose between 180 and 160mm of travel in incremental steps.

The Durolux, along with a number of other SR Suntour forks, features their novel QLOC axle system. Available in both 15 and 20mm sizes, the design works by simply flipping open the QR lever just like you would on a standard quick release, but you are then required to push a button on the opposite side that compresses the aluminum wedges, allowing you to slide the thru-axle out from the lowers. The QLOC design remains the same for 2012, which is a good thing because the system worked flawlessly on our '11 test model.

SR Suntour has some shorter travel contenders as well, including their premium Axon Werx RC Carbon model shown above. The 80 or 100mm travel fork uses lowers that are built from carbon fiber and topped off with magnesium dropouts and brake mount. The total weight of just 1550 grams is helped along by a trick version of the QLOC 15mm axle that uses a titanium skewer inside. It also employs a similar cartridge to the Durolux that shaves 80 grams, along with a tweaked air spring curve for a more progressive stroke. While SR Suntour were tight lipped, we have little doubt that they are working on a carbon crown and steerer version as well.

SR Suntour Axon Werx RC details:
• Intended use: cross-country and trail riding
• Travel: 80 or 100mm
• Adjustable rebound and low speed compression, remote speed-lock, air spring pressure
• Carbon lowers with magnesium dropouts and brake mount
• 30mm stanchion tubes
• Weight: 1550 grams

SR Suntour's new remote lock out employs two different buttons - one to engage and one to release the cable - but it's the release lever that caught our attention. To activate the lock out you push the cable pull lever down with your thumb, but to release it you simply bump the release lever, positioned on the side of the remote, with the side of you hand. Pretty clever system that is one of the most ergonomic designs we've seen.

 The 2012 Durolux looks spectacular!
The High speed compression is a huge improvement which will help tame the fork on big hits.
Then the clip on spacers is great, simple and very effective.
Im sad to hear there is not a 1 1/8 version as older frames will suffer like my TBC Double but, if its necessary then let it be!

RideOn!

 Yeah, it's a shame that there is no 1 1/8 version...

BUT! You can buy a used-not-working old Durolux, take both apart and just change the news uppers with the old forks 1 1/8 steerer! lol

 Yes, I have a 2011 so thats a good idea! They said all the externals are the same so the new dampers will fit great! RidEOn!

 I work with SR Suntour and talked to Mike about the changes at Eurobike. I think we just got our wires crossed talking to each other because it was so busy. There will be a 1-1/8" standard steerer as well. And all the people rejoiced.

 yaaaaaaaaa!!
1 1/8 is not the standard anymore but still the most versatile as it will fit any frame with the right headset.

That means :

.Tapered
.1-1/8
.Full length 1.5

3 OPTIONS. 'Nuff said.

 ShredLikeTrah, you are late.... when the article came out, there wasn't 1 1/8 on the list.

So we are not stupid. 'Nuff Said.

 I realize that everything suntour has made in the past is crap and is LITERALLY on walmart bikes. But I kinda want to give this fork a try, I wonder how it will compare to a rock shox or fox. But I dont have 500 lying around to spend on a fork that may or may not work the way I want it to.

 its only 500... Eek where do i buy.. ? ill test it for you Wink

 Damn you SR Suntour, now you've made me even more confused on what Durolux to get. I'm excited. If they sell it for around here for the price of the 2011 stuff I'm in.
  • 6 0
 Very interesting! Especially the Durolux! Big Grin

It's obvious that Suntour wants to step it up and be one of the best, and I think that with their prices, it's just a matter of time when we will see Duroluxes every day!

 Haters, I'm so sorry that you guys are blind due to branding mentality.
  • 4 1
 There's a difference between being blind by branding mentality, and having a pre-conception. Suntour as a company chose to create forks that could be mass produced for low end bikes. So in doing so have chosen the way their forks 'were' viewed and for what market they were aiming for at that given time. Creating a new fork is one thing, having good reviews as these have is another thing, but rising above the stereotype that they've created themselves will be the hardest challenge. I'm sure they knew this type of thing would happen should they enter the top end market. You can't blame consumers fully, Suntour as a company chose this route, and obviously it's worked well to enhance funding and given them a route to expand, but they also need to account for the way in which they're brand is now percieved.

 GSuperstar: I work with SR Suntour and gave Mike Levy the info for this Eurobike update.

SR Suntour's mission is to deliver a solid good performance product no matter the riders budget whether you buy your bike at a mass merchant or at the best high end bike shops. The performance and durability changes of course depending on those needs of the rider.

It is true this has been a ground up philosophy of low to medium range forks to begin with and to your point this does pay the bill. I believe we give entry level riders a good experience. The push towards high end has been a 10+ year journey for the company and it is now paying off in performance with World Champs in XC Marathon, XC Women's U23, Team Relay (2 of the 4 people on team France) and XC World Cup overall womens. Rinderknect took silver in World Champs and was 2nd overall in the World Cup. They have known that first and foremost you have to prove performance before image can change. We are working hard to earn your trust.

 Hi Sprockets

Thanks for the detailed reply. Every point you've made is of course spot on, my comment wasn't in regards to my view, just more of an explanation to pierrotlefou as to why on things like these you always get the same responses of 'but it's still a...'.

Unfortunately internet forums seem to supply an overwhelming amount of keyboard warriors that make an arrogant comment then head off elsewhere, not realising that these comments get seen by others and have a major effect. Take Kona for instance, everybody must know that these bikes are good, yet jumping on the bandwagon seems to be an internet forum way of life.

I hope my comment wasnt read in a negative sense by yourself, as stated the forks look good and are getting good reviews. Hopefully things can only go up for yourselves Smile

Best of luck!

 I'm just sick of guys bashing on them even though they haven't even used the products. My point is that the company is trying to show that it's stepping up. The problem is a lot of guys who comment that they're bad either never tested them, tested the lower or faked forks (yes, there are some companies who make crap forks then sticker them up as Suntours even Fox) or, really are just biased. I just hate that. Everybody deserves a chance to level up and be seen. I think the company really deserves to be seen in the good side of things. I used two of their forks, and yes they serve me well even until now. I admit, I can't afford high end brands, but in comparison Suntour's higher end forks seem to be at level with them in feel but with less bells and whistles. Looking back in the past, compared to today's new products, the current ones improved a lot. I hope Suntour would prove that they can go side by side with the other companies.

Good Luck SR! Smile

 Hey sprockets,

How about 1 1/8 version for us folks with older frames. Come on suntour, i've been waiting for this alternative and you will give us something that wont fit my frame. Damn you!

Edit- So i've read above that there will be 1 1/8 too and i rejoiced yay!
  • 3 0
 1 1/8 is the most popular steerer tube measurement for many bike that would use this fork and sr sountur doesnt have it for the durolux,shame,and the past durolux was not very usefull in serial use,past some days of abuse in DH,it turns crapy,i hope the new cadtridge would hang the hits and jumps in a better way ^^

 Looks great, and seems like a nice alternative to a costly/tough to service Talas. It seems like this is a step in the right direction for SR Suntour, although I think they need to work on their graphics a bit, seeing as how these are bland/ugly.

 I can't believe these boys are turning out good quality forks after all the shite I saw on crap bikes years ago. It's nice to see some companies turn around. Maybe falcon or Townsend will bring out an 8" carbon DH bike!

 Well that style remote lockout is very similar to the one fox makes with the help of shimano. i have on my blur xc that is very similar but has been out for a few years. it works super well and very ergonomical

 I don't quite get it why this new Axon is made out of carbon if it weights 1550 grams?! Stifness? - it could be, but doesn't have to be. And there are a lot of magnesium forks out there that are a LOT lighter?
  • 2 0
 Ye olde SID was 2.8 lbs a few years back. Wasn't even magnesium.
  • 1 0
 i think it's fantastic that SR is getting into high quality forks. I dont want to only see rockshox and fox being the only two nice fork companies when im older. Good job Suntour!

 It looks good but I am not convinced yet... My first "real" MTB (12 years ago) came with a SR Suntour fork and that was a piece of SHIT!
  • 1 0
 can anybody here verify if the axon is indeed 30mm in real life? because on their website its says that it has 32mm stanchions.

 Any information on what those new Durolux TAD cartridges will cost ?

 yeah but well ajusted derailleurs works... the forks are not even moving on some of the bikes!

 And the logo problem: Why not make a Degeneration X-like logo? The other side has "DX" on it.

 ive been riding bmx for the past 3 years......since when did suntour start making half decent looking forks Lol

 About the same time they started making all of Marzocchis forks, conveniently.

 Hi ninjatarian,

So you know there are completely different engineering teams and a different philosophy of building product too. Marzocchi chooses a open oil bath arrangement. For the past 10+ years SR Suntour has been building on a Quick Service Product (QSP) philosophy. It is a cartridge based damper that is easily serviced or replaced. Check out nikoniko's video on how to do an oil change to see how it all looks inside.

 Despite using different technologies, SR still benefits majorly from developing and producing another companies products, simple as that.
