#AskGMBNTech Brilliant video both. Really enjoyable hearing two guys talking shop who are experts in their field. Lovely bike shed too. Could loose hours in there rummaging. My question is in regards to a 5th Element coil shock I’ve got on a 2002-2005 (I think) Santa Cruz Heckler 5 I bought yesterday. It’s my first dual suspension bike (finally getting back into biking after 12 years away)and the element has been TF Tuned previously. As a complete but wanting to learn amateur, how the heck do I set this thing up!? Are they any quick settings I can tweak or do I need specific tools to get a feel or is it just worth getting it looked properly. Thanks and all the best both!

This is a great video, Doddy! More thorough interviews with the unsung heroes of mtb like this please - you know most of them, surely!

This was undoubtedly the best video GMBN has done in quite some time! It's always nice to have an actual mechanic talking about the shop info vs someone that simply watched a video and then is presenting it. And for future, PLEASE give us more of this and more info on setting up suspension.

Finn clearly knowes everything about bikes and suspension tuning, his t shirt confirmes that. (Kingdom brand tee)😁

I just purchased a Stanley Rotator Ratchet because of this video. I didn't know I needed one until today.

The man. The legend. Fin spends a significant amount of time repairing my screw ups! 😂

I remember meeting finn when I worked at TF Tuned as a summer job while I was at uni in 2012. Super cool guy and his VW Camper wheel spins ALL THE TIME. I also used to use the lathe he now has when I worked at TF Tuned to make shock spacers, so it's nice to see its gone to a good home!

Straight forward comments, humble in a lot ways.He knows his trade.Also years of hands work.

Love this kind of stuff. More please!

Doddy this was my fave ever gmbn tech video. Absolutely absorbing from stat to finish. Let's see more of this guy. When he said his fave thing was his lathe I knew he was a guy I could relate to. 10 out of 10

I would love more personal workshop tours!

#askgmbntech Hi guys, big fan of the channel. Please give us a rundown of the mechanism behind a H/L compression and H/L rebound adjustment dials work. What actually happens inside the unit to change how it behaves? Thanks!

@peglor

3 жыл бұрын

In most cases the fork is designed to act like a pump when it moves, moving a fixed volume of oil for every cm suspension travel (Though some designs probably tweak this as well). This oil is routed through a restriction that slows the oil flow down. Turning the adjustment dial adjusts the size of the restriction either using a needle valve type setup or a pair of aligned holes that are misaligned from each other as the damping in increased, leaving a smaller and smaller overlapped area between the holes restricting the oil flow. A one way valve is used so that the oil can easily go in the opposite direction to the flow when the fork moves the other direction, so compression damping only acts when the fork compresses and rebound only acts when the fork extends. Low speed and high speed compression add a pressure sensing element to the system so on a sudden impact, the spike in the oil pressure will open a valve temporarily to allow the oil to take a different route. The most basic version of this is the way most forks will still move if you hit something really hard while they're locked out.

#AskGMBNTech Is it okay, and if so, when and where, to do a shortcut/bodge in a suspension/dropper maintenance job task, where the proper and official way would be to use an expensive speciality tool that is only a one hit wonder.

1 - The Bushes are pressed into the lower and held in place with a retaining compound, Within the legs of the fork they are tapered so you can adjust the fit of the bushes to the upper by moving the bushes a few mm up or down, basically. 2 - By talking to other suspension techs and experimenting with different shims stacks & tunes

#AskGMBNTech I’m planning of racing enduro this year on my Santa Cruz V3 5010 with a 150mm fox 36. The fork made a big difference and I was wondering if a coil shock would it make my bike more capable and give me the grip I’ll need in those steep Welsh woods?

#AskGMBNtech Hello I always wondered why the Marzocchi dirt jumpers and dirt jam forks from the early 2000s had a nasty clonk when they rebounded, they worked fine when they got of the shelf but after the first time you took it apart they started clonking, I tried all kinds of thickness of oil but they never got as they where, I've lately been investigated the matter and realized that they have no valves for the oil just a big hole thru the piston so how did it even work fine from the start? Am I the only one why had this problem back then? Thanks for a great show!

@finlaypaton7202

3 жыл бұрын

Because they were filled with thick grease which will have coated all of the metal parts in the fork, then as soon as that mixed with the oil it looses anything to stop metal to metal contact, you can slow them down but it involves shutting off the holes and re-drilling.

Look on Fox's Tech pages - you need lots of special tools - you can do without 2 of them if you are clever, but it takes longer, you definitely need the filler tool and the tool that holds the valve open. The tools are priced I think to make it really not worth the home mechanic owning them, which I think is a real shame.

Pew Pew! Hi there !

My suspension Q. What is the optimum way to set up a coil for varying rider weights and skill levels. We should all know how to tune an air shock, but what about a coil shock for small, incremental changes?

@finlaypaton7202

First and foremost get the spring rate correct Once you have that. Then you can fine tune damping & preload.

Good if you are doing things like regularly carrying a heavy back pack, but pretty pointless otherwise. Several manufacturers now spec their springs in the exact poundage, or you could just look at a selection of springs on a dyno, to get the one for you. The spring rates can vary up to 10% on some makes - even the really expensive ones.......
