As usual, the best treatment of this subject on youtube. One thing I hoped Doddy would do is, for pedagogical purposes, explicitly call it "rebound damping" and "compression damping" rather than the shorthand "rebound" and "compression" since, to a complete beginner, a statement like "to reduce the pogo stick effect, add more rebound" sounds like the opposite of what you want to do-since an actual pogo stick already has LOTS of rebound. For teaching purposes "to reduce the pogo stick effect add more rebound damping" makes more sense and may be less confusing to a novice, though I understand the shorthand phrasing is completely understood by experienced suspension users.

Yes he means rebound damping, not rebound. Plus or a snail logo is more damping. It's the only part of the video I would change.

USD forks were introduced to motocross in the early 90's, with the road bikes not far behind. Conventional forks are still used on many models other than sports bikes. So USD forks on motorbikes are still called USD and conventional are still conventional. Exactly the same as on mountainbikes.

Also the longer the travel of the fork the more it needs to hang below the axle in a conventional fork. Just have a look at the last of the conventional MX forks. They were having ground clearance issues. MTB doesn't have anywhere near as much travel so it can all be packaged above the axle.

Great Video Doddy like always but this was especially action packed. Would love to see graphics of the insides of both with you explaining the airflow. I get that air is the main driver but when you talk about oil it confuses me a little ie is that just for aiding the slide? Is it air and oil that goes into the piggy back? In the coffee analogy is it the filter holes that are changing and not the liquid? I’ve a new Fox 36 but didn’t have low and high speed compression. How does that work?

@James-dn1hu 3 жыл бұрын

If your talking about rear suspension it’s based on the travel that the axle moves in and with the added leverage and depending on design the axle will move 130mm rather than the actual shock shaft being this size.

Hey Doddy Great informative video as always. I have a question about rear shock reservoir location. Last year I went to a bike show here in Toronto and one of the things I noticed on most of the long rear travel bikes was the rear shock reservoir was located at the rear of the bike more so attached to the left chain stay,but I have yet to see this again any reason why. Thanks

First suspension fork was a triple clamp sr suntour which came on my Saracen Raw DH circa 1998, they were absolutely poo. I upgraded them to a set of RST 461DH with a massive 100mm travel, the off white with red lettering looked mint on the black and red bike. I then upgraded the rear shock from a no brand piece of crap to a rock shock deluxe I got off a friends brothers old voodoo frame. Thing was a tank but a plusher tank after those tweaks. That was the glory days of the sport, the World Cup XC and Dual came to Newnham Park in Plymouth, as a 12 year old lad going to a place within riding distance of my house and watching Steve Peat , Brain Lopes, Wade Boots etc race made a serious impression. The money in the sport back then was crazy!

The top MotoGp Forks are hardly "over built" for strength. They're as light as they can possibly be, the expense isn't important in any way which is what actually gets the hit, the price of making them. Yes they're to big and heavy for a MtB, yes they can be heavier as the engine takes the strain not you but over built? Nope. Great video though as usual.

#askGMBNtech I have had a hard time finding good discussion on when, for whom, and why the mid range forks are good enough. Or perhaps more important what terrains are mid range forks always going to be adequate, when/what will be speeds that just reach the limits of those forks. Another point in that discussion I'd like to see is for bigger riders, bigger weights. Currently, I know low end forks are adequate for many folk because they really don't ride at all. Mid range forks tend to get called trash by most riders' comments and reviews with very little reasoning in the dismissal.

@fenderbenderspecial 3 жыл бұрын

I'm as confused as you are in this regard. It'd be nice to hear Doddy's thoughts on it. I have been riding a 10 year old, second-hand Rockshox coil fork for years. I have no complaints. I recently built a bike with a Suntour Durolux 36 and have been really enjoying it. Both of these forks are considered mid-tier, but I've had a blast riding them. Is this because I don't know how nice the mega-expensive ones are? Is it because I don't ride hard or fast enough to need the snazziest fork? I am ~200 lbs, maybe a touch more with all of my riding gear, and these forks have held up well under me.

#askgmbntech probably will come up next week but I've noticed there are huge differences in anti rise numbers. Unlike anti squat, where most designers are aiming to get 100% or a tad more through the travel, anti rise numbers can vary from 50% to 100%. Could you explain how these numbers could translate to feel and what scenarios a 50% anti rise bike would be better than a 100% anti rise? Also, how do you tune a shock with a complex leverage ratio graph shape?

The other advantage of running USD forks is less unsprung weight,, which is why high performance road and dirt motorbikes tend to run them. The big negative of USDs, however, is having the fork inners far more exposed to damage from rocks, etc.

@benfairhall5331 2 жыл бұрын

Are you talking like volume spacers? Ok say for example your 90kg and to get the correct sag for yourself you need to use 25% for sag. To get this sag number for yourself you might need to run say 120 psi which is max psi for fox forks adding volume spacers should reduce the air pressure needed to do the same effect. So after you put in say 3 volume spacers you might be able to knock the psi back to a 100psi by doing that you will also create a much more progressive dampening curve and instead of sort of being the same stiffness the whole way through the stroke it will seem much plusher on the initial stroke and then ramp up towards the end

A couple of things here. Moto-forks started out just like our conventional forks of today. The "upside down/inverted" fork came much later than the conventional fork. Doddy, you're probably too young to have known that. :) And for Gods sake people. Your mountain bike has a FORK on the front (singular), it's not called FORKs (plural), there is just one fork on your bike. Sorry, just a pet-peeve of mine.

#askgmbntech Hi Doddy. I absolutely love the show! And I need your advice: I'm planning to replace the RS Monarch Plus Air Shock on my 2017 Specialized Enduro 650b with a Cane Creek DB Coil with a progressive spring (450lbs; BikeYoke low-geo yoke to mount). With gear I'm 63kg/ 139lbs. Leverage ratio of my Enduro is 2.98 with a rather linear curve from what I could find out. I don't need the adjustability of an air spring and I feel with my current setup the rear wheel grip isn't great. Do you think a progressive coil is the way to go to gain more grip? And would a coil shock make me feel the trails more or would it rather deaden the feedback? Cheers!

USD forks are USD forks as motorbikes started with conventional forks. Another advantage of USD forks, less unsprung weight. There was a lot of discussion around USD and stiction vs conventional forks... this was mainly with high energy use like motor cross and race bikes. A down side of downside forks... the staunches (we tend to pronounce it storn-shins in NZ) are open to damage from lower leg hits which is why the large plastic fork leg protectors on motor x bikes. Linkage forks have an advantage of no stiction but an increase in failure over weak points at the crown for the girder fork and forward weight countersteering of the 'Trailing link' fork design. I chatted with the pit crew of the most beautiful race bike ever built, the 'Britten V1000' that brought out the 1st successful trailing fork system and was told one of the main reasons John Britten made the forks.. was that 'they could". They weren't any great advantage and there is a good bit of footage of (i think Andrew Stroud) testing the bike, which was wheelie happy, when the forks failed. If you have never heard of the Britten V1000, check it out... It's not very often when a bike built on a farm at the bottom of the world, takes on Factory Ducati's at Daytona and not only pull up beside the 2 front runners.... but then proceed to pull wheelies beside them while they were full throttle... then leave them behind... wait.. where were we... oh yes MTB... there is also a fork I have seen that runs a rod through the crown and through a lever, runs the shock on the frame, removing all the weight from the forks. I've got a 2010 Giant Faith 0 with Rockshox Totem Solo Air forks (40mm staunches)... the stiction is quite bad. I tip the bike upside down before a session to wet the seals but long for the plush feel of my old Foes with Boxxer tripples.
