MTB Suspension Tuning is not as complicated as you think

I teach Dan how to tune a RockShox Super Deluxe MTB shock. We swap it's factory set Medium Compression Tune to a Lighter tune after this modification was suggested using the Quarq ShockWiz.
You can find the RockShox Rear Shock Piston Tuning Guide here.

I do not always agree with you on groupsets and tech... but I am always deeply impressed with the quality of your work in the workshop and the customer service!!! As an engineer myself, I am very happy that there is at least one shop in the bike industry that is doing a great job!

[@Mapdec]

I’ll see you in the comments on Thursday. 🙏

[@knott4me561]

Everyone is an engineer, right .

[@luca_dierks]

Lowers service on the forks once or twice mid-season plus a coil shock that does not need much maintenance during the season are my happy place. I'll be happy to pay a professional once a year to take care of the dampers service for me 😂

[@sportsrecoveryonline8802]

Nice one Dan 😊

[@sabamacx]

9:46 safety squints engaged!

[@ionutandrei8362]

Great video! Thanks!

[@Mapdec]

Glad you liked it!

[@LaurentiusTriarius]

Everything is so tiny yet so strong. Fluid mechanics are so friggin impressive. I'm surprised they don't sell shims individually tho, for like 20$ each 😅

[@Mapdec]

Oh. Keep that idea quiet. 🤫

[@user-kf5db3ob8o]

Nice video - good to see more competent young folks being proud of the excellent work they’re doing! Ps. What’s the neat blue tray on the bench for stopping the bits going everywhere?

[@Mapdec]

It's a soldering tray. Heat resistant silicone. good bit of kit.

[@user-kf5db3ob8o]

😊

[@leewhittle4340]

Great video as usual 👌. If I wanted to grease my fork and shock stanchions to keep them slick , what would you recommend ? I bought some xhp222 after watching your videos , would that be suitable ? Cheers Lee.

[@Mapdec]

Definitely not! Use something like Juice Lube Fork Juice or RSP Hyper Wiper

[@Maxibsa]

At the moment the Hunt 44 UD Carbon spoke wheels are reduced. What do you think of this wheelset? Can I buy them ?

[@Mapdec]

Don’t let me stop you. If they are cheap enough, just consider them disposable.

[@Maxibsa]

@@Mapdec I will Go with the ffwd ryot 44. Just gonna Save some Money

[@sabamacx]

0:44 alternatively swap to a heavier weight oil=more compression, no revalving needed.

[@Mapdec]

This would also alter the rebound and every part of the shocks function. Remember the shims are designed to open progressively at faster shaft speeds. At low shaft speeds most oil is routed through the needle valves.

[@sabamacx]

@@Mapdec agreed. In theory and on a well made shock, rebound and compression should be independent of each other. In practice, there's a coupling between them and fluid viscosity that seems proportional to how expensive the shock is, and the age of the oil.

[@michaelclements4664]

Using nitrogen is a nice touch :) I wonder how many bike shops do that?

[@Mapdec]

I’m sure the MTB specialists do

[@stefandodik1780]

Using the Knipex at the wrong direction, better not use it at all, and a tech shop without vacuum bleed pump...eh

[@Mapdec]

Thanks for your input

[@naromsky]

What a nightmare.

[@Mapdec]

We enjoy it

[@LaurentiusTriarius]

That's the fun part. Suspension tuning yield results... Tbh it's not that time consuming compared to dirtbikes; you'll have some nightmarish shock services, everything falls apart and gets damaged very easily, oil is always contaminated even after a couple hours, you also have to adjust valves every 20 to 40 hrs, amongst other things! Amish bikes are easy 😂

[@GHinWI]

That’s a job I’ll happily pay someone with the tools/equipment to do for me. Too much mess & specialized training.
