Here's the Latest Long-Travel 29er Fork – Taipei Cycle Show

Suntour Durolux 29 fork
For years, it was slim pickings for anyone who wanted a long-travel 29er fork. We’ve come to a relatively happy place, with the Pike, Lyrik and 36 all on offer. Now, Suntour is set to add the Durolux 29er fork to the mix. When the fork eventually hits the market, it’ll sell for $800.

As with the Durolux 26 and 27.5 forks, the Durolux 29 features the company’s R2C2 damper, which allows you to tweak low and high-speed rebound damping as well as low and high-speed compression damping. The fork also features the company’s Piston Compensator System (PCS)—a coil spring-backed internal floating piston that reduces cavitation and allows for easy system bleeds.

Suntour is still steering clear of going the ever-popular, expanding bladder route, arguing that while internal floating pistons aren’t exactly shiny, new and full of sparkling whiz-bang factor, IFPs are time-proven and reliable.

Reliability and ease of maintenance is, essentially, Suntour’s thing. Their forks are rarely the lightest. The Suntour representatives admitted that the Durolux might be a quarter pound heavier than some of its competition, but they contend that their cartridge system’s ease of maintenance is a worthwhile trade off.

You’ll be able to wring out 170 millimeters of travel from the Durolux 29 and if you feel like shortening things up, you can reduce travel by tossing in 10-millimeter spacers. If you’re the kind of rider who wants a ridiculously over-the-top 120-millimeter travel 29er fork, you can turn the Durolux into that kind of beast. To each their own.

Suntour's R2C2 damper lets you fiddle with the fork's compression and rebound damping until the cows come home.

A smoothly-integrated mud flap is always a nice touch.

The Durolux 29 is currently configured around a 15-millimeter through axle, though a Suntour representative pointed out that, “Today, it’s a 110x15, but with more machining it could take a 20-millimeter axle. We left enough material on the dropout for that…. should the need arise.”

Wait a second. Will the need arise?
“It’s coming.”

Make of that what you will.

Plenty of material left to machine away and make room for a 20-millimeter through axle...

 Dear Fox, Please make me a fender for my 36 that fits as seamlessly as this one. There's already threaded holes on the arch FFS... K Thanks Byeeee

 Suntour makes great forks at a great price. My Durolux rear shock works great too. Dual air can rebound and compression dials that have a wide range from slow to fast ect. 20 mil axel is a good idea on a 29 inch wheel.

 My dick moved when I read 20mm axle
  • + 1
 @gonecoastal: mine moved when I read 26"

 I feel like they should've went straight to 20mm. Or made a system like fox that can take both. If they made this lineup all 20mm compatible, I think it would turn a lot of Pinkbike users onto it
  • + 14
 Except there aren't any 20mm hubs that have the correct rotor placement for running boost... Yes, boost and non-boost would both be 20x110mm but the hub flanges and rotor mounting location would be in different spots...
  • + 6
 @j-t-g: ah really good point. Didn't think of that. Gotta love those standards lol
  • + 5
 @j-t-g: argument is not valid. When they launched 15x110 boost there were also no hubs with correct rotor placing. Therefore yes they could and should have gone 20x110 directly. Yet another sign of stupidity of our industry leasers...
  • + 3
 @EnduroManiac: not all new bikes feature boost forks, and sure as hell no one is 'upgrading' to boost front end. I would be very surprised if the idea of 110x15 is catching on, it may finally be time for the mtb giants to stop trying to make existing standards obsolete to drive product sales and actually just go with what works better, what has worked for a very long time and what already exists... 20x110, you can make fork legs wider apart without increasing axle width if plus tyres is your thing too.
  • + 4
 @j-t-g: Oh yes! You can just smell the new standard coming around the corner - Boost.20.
  • + 2
 @j-t-g: Too bad they went with PM disc brake mount. The IS2000 disc brake mount could have solved what. That said, 5mm is a huge pile of spacers. But a slightly different (thicker) IS2PM fork adaptor could solve that too.
  • + 6
 So its still not safe to buy anything. Ill check back next spring.
  • + 1
 Wasn't the first boost standard made by Trek in partnership with SRAM? Why would SRAM get rid of their 15mm standard that they had already claimed to be ideal?
  • + 2
 @ajdriscoll: 15mm was a joint effort between Fox and Shimano. Sram fought it saying their 20mm maxel light was both stiffer and lighter than the Fox 15mm axle but when you have 2 giants of the industry pushing a standard the rest followed.
  • + 5
 I remember the old days when 80mm of travel, according to the companies, where enough for 29ers. It was all about the wheel size.
  • + 13
 I remember when 80mm was a DH fork. . . I must be getting old.
  • + 10
 I remember when 0mm was a dh fork. haha
  • + 1
 @timmyelle: I read somewhere that my forks also have negative travel. That must be proper Flintstone stuff right there.
  • + 1
 @timmyelle: I remember when tires were made out of rocks and how you had to shift your chain with your fingers

 All hail your new long travel 29" overlord's!
  • + 4
 God bless Sunotour for knowing that 20 mm axle is the only good axle for forks!
  • + 7
 Making 20mm great again!
  • + 1
 And the industry fks us again and 20mm will become the new std again, yeah right nice one! Btw not aimed at Suntour, always said 15mm was the biggest rip off since Jack the Ripper! And consumers bought into that BS... I want to know is it soft off the top with out being a pogo stick, with pro mid stroke support and ramp up tuneability that's what I want to know!! Give it to me and I'll test it...
  • + 4
 A "long travel" 29-ER fork is more in the 170mm range now right??
  • + 1
 There are already 170mm 29er prototype forks out there...
  • + 1
 If these ones are built like the 27.5 durolux then you can take a spacer out to go to 180mm travel. On the other hand they could have just used 27.5 uppers and made the lowers just a bit longer to fit the bigger wheel. They may have an internal travel adjuster but they may not, we'll see i guess.
  • + 6
 @Dustfarter
It will be able to do 170mm which will be its max. The A to C is 590mm. This fork uses different uppers from the 27.5" as the width is wider allowing to fit 27.5"+ tires as well as 29"
  • + 1
 @SintraFreeride: There are already people riding 170mm 29 Lyriks.
  • + 1
 @Dustfarter: 170 lyriks 46 or 51 offset?
  • + 3
 Love them...but do you need 160mm travel on a 29er fork?
  • + 2
 For sure.
  • + 2
 Sometimes...wreckoning/slash/range owners maybe
  • + 2
 Im calling a Wreckoning on that one or maybe it's too Enduro for you!
  • + 1
 There are more than rumours of a 20mm boost axle now ... 20x110, but with the disc slightly moved outside ... Stupid you say ?
  • + 1
 I want to fist-bump SR Suntour right now. Do you have any idea how hard it is to find a 140mm 29er fork that won't cost my kidneys and 1/2 of my liver?
  • + 4
 offset options?
  • + 5
 @PHeller: all current @SRSuntour 29" forks are 46mm offset. Not sure if both 46mm and 51mm will be offered on the Durolux 29
  • + 5
 @PHeller
Offset will be 51mm for this 29er as are all new 29/27.5+" forks we are making
  • + 1
 Doubleposting.
  • + 3
 @SRSuntour: Thanks for the info
  • + 2
 Awesome that a tone of new 29er options are hitting the market, but I'll be waiting for a 170mm option.
  • + 1
 This one can do 170mm
  • + 1
 Love it! Maybe my just bought Auron PCS will go to classifieds when this baby comes up!
  • + 1
 It will be interesting to see damper on the table. I hope it has a shimstack now
  • + 2
 Shut up and take my money.
  • + 1
 It's not a major detail, but I have to admit, I really like that mudflap.
  • + 3
 @Vaclav: Every fork manufacturer should include a mud flap.
  • + 1
 Suntour is great. I love my auron fork. It's lovely.
  • + 1
 Stanchion size?
  • + 3
 36 mm same as the 27.5 version.
  • + 1
 @sprockets: thank you!
  • - 1
 so you are telling me they can make the hole bigger? mind = blown
  • + 2
 Sounds easy enough but works only if there was enough material planned for...safety first. If optimized for 15 mm it wouldn't leave enough to go 20 mm.
  • + 2
 @sprockets: wow it sounds like they made it for both holes. incredible
  • + 9
 @MmmBones: One shaft, two holes. Perfect.
  • + 0
 @ratedgg13: they musta really put their heads together to come up with this great idea
