Pre buying my first ever full suss bike (an Atherton AM.130) with some 30yrs of hard tails I hadn't given suspension much thought. Now a year into full suss riding with Fox Factory shock & forks I'm in danger of becoming a suspension nerd/bore ... love logging all ride settings, and aiming for the optimum set up. Have gone from the standard Fox fork sag of 15-20% to a 25% setting, much smoother on the forestry trail tracks I ride on. Love Neils presentation style and skills, more from him especially in the area of theory v actual riding feel....not just big jump offs or DH daring do but typical 'average Joe' off road riding.

J- tech tuned a new shock to suit my weight, riding style etc. But they refused to give me any idea of what they'd done to it which I though was crap. I'd like some idea how it'd been "improved".That shock failed 6 months later so I got warrantied a new shock from the manufacturer - with standard tune. The standard tune felt much better than the J-tech custom tune. I wouldn't use J-tech for a custom tune again - mainly because they will not tell you what they did. This means any future mechanic will have no idea what's been done to it too.

Hi Graham, really sorry to hear you've had a bad experience with us. With regards to the refusal to give information, I think there may have been a misunderstanding or a miscommunication there. We're more than happy to share info for someone else to service the shock after our tuning, so oil specs, IFP specs, etc. We're just not willing to share shim stack configurations, as that's something we've spent many many hours developing and so is our intellectual property. Again, sorry if this was miscommunicated in any way. With regards to you not liking the custom tune, I'm really surprised to hear this, as we get lots of positive feedback from our tuning, which is based on many years of data collection from real-world testing, which is correlated with many hours of dyno work in the workshop. Not saying we never get it wrong, but if a rider is struggling, we do everything we can to help get the tune to work the best for their needs. It sounds like maybe something went wrong in the process, so we'd love to hear from you so we can look into the details of this. We obviously can't help now with that specific shock, as you've moved on to a replacement, but if you could spare some time to give us more detail on a phone call or email, we'd be very grateful to find out what went wrong and try to make it up to you somehow. Our email is service@j-techsuspenion.co.uk and our phone number is 01743464486. Many thanks.

@@j-techsuspension No, there was no confusion or misunderstanding. I didn't want to know about specific oils or shims etc. Just an idea of what was done - eg, increased or decreased the range of compression or rebound damping etc, or increasing the number of volume reducers. Basic stuff but I was told quite bluntly that I could have no information.

I wiil vouch that if you are a heavy rider, it would be good to get your suspension tuned for your weight. I blew out my Fox DPS and sent it to Fox. They asked my weight and tuned it accordingly. I'm here to say the shock is unbelievable for a low end shock. It feels just as good as my Fox Factory Float X2 with 10 more mm. On a side note, for you heavy riders. I switched forks from a Fox 36 to a Fox 38. BUT I bought it with an E-TUNED SUSPENSION. This specific tune from Fox is for a heavy E-bike but I don't ride an E-bike. I'm 210lbs dry and I'm saying this fork is mind blowing, as far as the amount of traction through rough fast plowing. Id say if youvare a heavy rider don't buy a regular fork if you can fit an E-TUNED fork on it!

Is any silicon spray suitable for lubing stanchions? It won't contaminate lower leg oil?

@janprachar5066 20 күн бұрын

I would suggest using the same oil that is in the lower legs.

@rider65 18 күн бұрын

Ditto. What I do is spray a very small amount of silicone on a clean rag to wipe off the dust seals & stanchions. Then use just a little bit of the fork oil around the dust seal stanchion for lubricating the inside of the seal

@stevenconnor4221 18 күн бұрын

Silicon oil will just help lubricate your seal and provide less stiction.

What is a suspension tune? Is it more than just chucking as spacer in?

@MightyFireL 20 күн бұрын

Valves layout in the damper according to your weight and riding style. And for rear shocks, also depending on the frame kinematics, and what personality the bike manufacturer wants to give to the bike.

@JS-up8ff 16 күн бұрын

I think the 50 and 200 hour service interval are really pushing the wallet for the customer and filling it for folks like Jim. Of course he says to follow the manufacters recommendations. When you buy a shock for lets say 400 euro, I'm not going to service it each year at almost ±180 euro. I will just run it for 2 years minimum and just throw it away and buy a new one (and maybe they even made a new version, win win). With the forks, it's a bit different as a new one is mostly 700-1200 euro and service is ±150 euro. But that's also easier done yourself. Just seals and oil/grease. Rear shock is way too complicated imo.

@cornishcactus 15 күн бұрын

yup, my forks get a lower service when i feel they aren't smooth, so 9-12 months and full seal swap every couple of years. Haven't touched the damper because it sits in it's own sealed up little world away from dirt and should be sweet for years. Shock I'm doing only it's 2nd ever service at some point soon in 5 years, and that's only because I feel guilty, and want to see if the 10mm damper rod is still unscored.

Basically no suspension tune tips in this video :D Apart from everything that has been already said 999+ times over the Internet. Let me share my suspension tips from a noob, that just recently found out how to properly set the suspension: - SAG is just a starting point. Just set it somewhere in the area of 20-25% and you're good to go (30% for damper). If you bottom out - add volume spacers. If you feel the fork is too soft - add compression. Try not to go lower than 20% of sag. - Set your rebound as fast as possible!!! I've ran too slow rebound for over 2 years and was struggling from arm and hand fatigue. I thought Im getting thrown of the bike. I was, but because I had no travel left, not because the rebound was set too fast. Just make sure its balanced between front and rear (a tad slower on the rear is fine). But generally you want that fork moving fast. - Compression - use manufacturers recommended settings (for Chargers - just open it all up). Add low speed compression for more support in berms and pedalling, add high speed compression if you're blowing through travel on rough stuff. Thats it, enjoy and ride.

Come to find out that the deal on my 160m Fox 36 Perf. bc it's a thicker ebike build, using 34 spacers, less volume, and a given tune. Still good for my usage, tune it to my weight. Lockout good for street. Allows for the 220mm SRAM rotor for XTR brakes im running, 203mm out back. Niner Air 9 hardtail. Wait for the real bomb, tho. Wait for it...

This is the first I've heard of "lubing your stanchions" after each ride. I clean the stanchions to get rid of dirt and grit after each ride, but what do your lube them with? The manufacturer's fork oil? WD-40, Silicone Spray?

@tommyking207 20 күн бұрын

Suspension lube spray. There are a few makes. Spray your stantions once you've cleaned your bike an cycle the Suspension to lube the seals an also it brings up crap from the seal which can then be wiped off. 👍

@TivonSanders 19 күн бұрын

I use RockShox 15wt oil to lube my stanchions. I just apply some to a folded up towel and apply the lube on the entire circumference of it right above the seal.

@rider65 18 күн бұрын

What?! 😂 dude are you serious? You should at least clean off the stanchion seals after every ride. You could Lube the seals and the stanchions every other ride but don't use too much silicone type of lubrication that will dilute the fork oil. The best lubrication is the same type of hydraulic oil inside the forks. You don't need much just a little bit on your finger after the stanchion and seal are clean work the stanchions up and down wipe off the excess and you're good to go. Same goes for the dropper. 👍

All this talk of servicing makes me want to stick with my Suntour Aion 35 forks... as far as i remember its only the lower legs that are actually serviceable, and the damper is a sealed unit. It feels as good as a few Fox forks that I have ridden (maybe they could have been dialled in better?) but I'm happy 😀.
