Adjusting the travel on a SR Suntour Fork is Easy!

[@patchesthejaybird8431]

I remember fork travel being easy to adjust. It was a common feature. Pike forks had a way to just dial fork travel. Now it seems like forks have gotten harder to adjust. Fox and Rockshox have moved towards shaft replacement to change travel. Glad to see SR has kept a simpler design.

[@ToogyHowser]

yes, it's super easy

[@patchesthejaybird8431]

I thought about it more, and I must be partly due to a move towards air springs. The old dial adjust on Rockshox Pikes was only on coil sprung forks. Anyway, hats off to SR for not requiring a shaft replacement a la RS Fox and others.

[@GoodTrails]

I don't ever plan on taking my forks apart. But, this was oddly satisfying to watch.

[@ToogyHowser]

yeah once you do it a few times it doesn't seem so bad haha

[@infamousdnt]

The suntour is QSP its meant to be taken apart. Its easy to do if you just watch a few of their service videos.

[@robinrai4973]

Convert it to an oil bath! Add the foam rings and 10ml of fork oil in each of the lowers, makes them REALLY supple!

[@anbudrew]

I was surprised when I heard you say milimetre. I was like I didn't know USA liked to use metric in their videos. Then I heard the "out" 😅 Anyway thanks for sharing. Saving this since I'm planning to get a 27.5 Auron for my San Quentin

[@bentodd7535]

Does anyone know where I can buy the travel adjuster clips? I looks on suntours website but couldn’t find any

[@LuisRDC]

About the air chamber: ¿Wich oil should we use ? i have the WPL forkboost oil and i´m wondering if it will be ok to add a little bit on the air chamber, i think it´s a bit heavy/thik oil and i don´t wanna make it worst.

[@PJSinohin]

Thanks for sharing this. Planning to get this fork model. Currently have epicon on 140mm for 27.5. Did the adjustments myself from youtube videos. And i learned another one today.

[@danwright190]

Hi, is this the same process as the aion 35 fork. As I'd like to set the travel to 160mm. Thanks

[@ToogyHowser]

yes it is!

[@lochlanbrown7282]

Hey, I am wonder if I would be able to do this to my Suntour Axon fork and if so will the process will be the same. Great video btw.

[@jf8534]

Same oil I use too. Thank you crappy tire. The servicing of my raidon is something I'll be doing soon.

[@ToogyHowser]

Good luck, working on Suntour forks is pretty easy

[@jf8534]

Thank you. I've done it many times. I even have 2 tokens in there. I might go back to 1

[@gfxman14]

so you added a spacer because you wanted 10mm less of travel? does that do anything to the volume of the fork, as in making it stiffer or less chance of bottoming out?

[@gfxman14]

sorry I commented before the video was over. The spacer you added to the air shaft side, on the coil, what does that do? And adding the gear oil and spacers on the other fork takes volume away, why do you need both? Would the spacers alone do it, without adding gear oil?

[@ChrisD-h8f]

how much travel could i drop 150mm on these forks? Do you have a link for the spacers?

[@richardjensen3655]

You dont have to hit both bottom bolts with a mallet? The lowers come right off simply by removing the bottom bolts? My axon's lowers can't come off, I supposedly didn't hit the bolts hard enough.

[@hrhuerto]

where can i buy the spacers

[@engrross0209]

Can we replace the Auron35 negative air spring with the EQ air shaft assembly as an upgrade?... is it possible?... thanks

[@desgamble9220]

Thanks for the great video. My near new Aions rattle like crazy over bumps. Any ideas on what the problem is? Many thanks!

[@bakerdeathwish88]

Did the auron have stock volume spacer on?

[@christophercolumbus5816]

Hi! I have an XCR34 Air suspension fork on my Canyon with 100mm travel. Do I have to remove or install spacers to increase the travel to 130mm? The spring fork goes from 100mm to 130mm.

[@RogelioMtbRider]

Nice video! I didn't know that santour doesn't have oil at the lowers like the other brands. I have a question. Since the lowers are using grease, then the two bolts on each lowers near the mounting of the brake piston is use to insert grease inside the lowers. Is that true? Also, since you put a fork oil on the rubber seal of the stantion and press, then the water also can enter?

[@breppe443]

A bit late but the two bolts you're talking about is just easy access ports to put gear oil on the foam rings. Two drops max on each side from personal experience. As for the case of water getting in the fork, I've been riding my Auron most of the winter season and even dropped my bike into a stream but I didn't see any signs of water getting in. Hope this helps.

[@smarttask1]

My lockout has stopped working on my Suntour Aion LO-R 35 150mm. I have looked but not found any information on how to adjust or why this has happened.. any help would be appreciated...

[@ToogyHowser]

I don't think the Aion has a true lockout? Most forks don't. You can ramp up the compression but it's not a true lockout.

[@abzyberdy]

There are some mystic things about sr dampers. As i serviced my raidon fork, i compressed it without air up side down, this resulted in lockout stop working. There are different size hexes like 2 and 5 under the lockout cap and i managed it somehow to make it work again with turning them. There was a video somewhere on youtube, how to fix this problem. This 2 hex screws allow as well to adjust how much travel remains after locking the fork, from solid hard to 5-6 mm of travel, or even loose, so the lockout dont work any more.

[@krisnowakowski]

hi guys , i got the problem with the nut of rebound side (4:10 min). when i try to unscrew it , it just move around . any tip?

[@magnitto]

I followed the same steps but I couldn't get the lower legs removed, feels like negative pressure pulling the legs upwards whenever I try to pull them down. I tried to tap on the lower legbto release the trapped air same like what I used to do on the pike but now joy. The tapping has now made some dents as well to the nut and o probably need to buy a new one as its not tight ingredients Any idea how to remove the lower leg and where to buys spares from

[@BriansRCStuff]

What is the max number of volume spacers that fit? I just keep bottoming out with the stock setup and want it a little stiffer on the 2nd half of the stroke without loosing the plushness.

[@Ryan-om1pr]

Could they be lowerd to 100mm? I need a jump fork that will comply lock out. i work as a bike messenger. And want to ride st in the downtime

[@DoctorORBiT]

Checkout the Suntour Manual on their website for your specific fork. It'll say exactly what your travel range of the fork is! (For this fork, the Auron, it's minimum is 130 afaik)

[@allanridesbikes5856]

I have an SR Epixon. Does changing the travel on these forks also change the total fork length? I'm asking for the sake of how it would change the stack. I noticed that my Epixon is set at 100mm but the stanchion that is exposed at rest is at 120mm. I'm wondering if changing it from 100 to 120 would or wouldn't change the fork length.

[@gabsantiago7676]

Is it ok to use gear oil or fork oil on the stanchions?

[@BicMichuM]

Does this apply to all suntour? I have a xcr lo air set at 100mm but max is 120mm...so if u want more travel u take out those spacers right? Just trying to learn coz bike shop charges around 1hr job smh

[@jomarlontoc8004]

[@andrejrajnoha3938]

Great video. I have a Suntour Raidon XC and I want to set 120mm travel with the same air volume spacers in upper part (It has actually 100mm). I want to keep the same progressivity with bigger travel. Is it possible? Can I keep the air volume spacers in the positive air spring there or I need to remove them when I increase the travel of the fork? Does the progressivity change if the travel is bigger and the upper spacers will stay there? Thank you.

[@liamzonneveld8129]

Hey toogy I have a lower end SR Suntour XCR Air fork with a remote lockout. I'm doing some more aggressive riding and I'm wondering if I will be able to adjust the travel on this fork since it isn't as high end. Do you know if I can do this and if so would you recommend it?

[@ToogyHowser]

I think this only applies to their air forks

[@abzyberdy]

Raidon forks are also made to be adjustable from 80 to 140. But my one which came with the 2019 giant fathom 2 was not like this. Only 120mm travel availibale. But i did put some 15wt oil in the lowers just like the rockshox and it works very smooth. You can also change the progressivity of the air spring even if its not made to take volume spacers. Just add bit more Gear oil into the airchamber.

[@vortexmacher6904]

does this work on all sr suntour forks like the SR SUNTOUR XCR34 AIR one ??

[@jekferrer]

This is great! I'm about to purchase a Suntour Auron 35 Boost 29ner with 160mm travel, but the frame that I have can only accomodate up to 150mm travel, Is it possible to lower it. Thank you

[@fenderbenderspecial]

The suntour website lists the range as 130-160mm for a boost Auron 35 29er. It should be easy to get it to 150mm or below for your frame. You'll need to have extra spacers, though.

[@oklahotb3217]

Nice Job Toogy

[@ToogyHowser]

Thanks man! Hope you are staying safe!

[@TheFatSteez]

Thanks for the video mate! So do only the bottom spacers effect travel length and those top volume spacers were just for making the fork stiffer?

[@ToogyHowser]

yes, well the volume spacers don't necessarily make the fork stiffer, I think it just adds mid stroke support, I think? I'm certainly not an expert on this! lol

[@nikolavrckovic1588]

Hi there! I really like lock out mode. But as i understand this RC2 damper don't have it. How does it behave when u put compression damping on maximum? Does it still dive when pedal hard standing up?

[@ToogyHowser]

not any worse than most other forks like this

[@GlobalPictures]

Did lowering the travel change the head angle?

[@stevebennett3587]

Great video, I have a lower end xcr32 air, not sure if i could increase the travel, but 100mm is enough for my style of riding, but was wondering if this would be similar to servicing my fork, and how much maximum psi i can run these at, at the moment i run them at 130psi and I'm 90kg, your advice would be much appreciated?🤔

[@marlonmugot4069]

Hello their, can sr suntour durolux lowered to 140mm travel?

[@patchesthejaybird8431]

Wow, nice fork. Suntour's high end line looks well engineered and constructed. Did Suntour recommend the synthetic gear lube for their air piston seals? Seems like a cost effective solution. I remember Rockshox Redrum of the past. I still have a little. It was probably similar to that gear lube, but red, and expensive, if you could find it.

[@ToogyHowser]

yeah they recommend a little heavy oil in the air chamber, and yes Redrum would basically be the same thing!

[@patchesthejaybird8431]

@@ToogyHowser I think the synthetic gear oil will be on my list in the future. I probably only have 20cc of red rum left. I bought that from a shop about 17 years ago, they just poured it from their bottle into a small bottle I had. LOL.

what is the difference between the spacers on the rod and the spacers under the top air cap?

the "spacers" under the air cap are actually volume reducers, they don't effect travel.
