Ryan, those sliders are a cool idea! Erwan, if you interested or need, I could help you print some and send them over

There’s a quicker way to see if you’d like what a swing link does. You could 3D print small sliders (blue) and mount them on the seat stays. These sliders would keep a small gap between the seat stays and the seat tube (or its protector, shown in red). As the bike flexes, the sliders would hit the seat tube and act like a bumper and stop the frame from continuing to flex. You can print and bolt them onto your bike now to test if the added stiffness feels good. It might feel a little weird while riding for...

Right now, it looks like your main loss of stiffness is coming from the seat stays not being supported by anything other than the shock. The shock is essentially acting as a structural member of your bike, taking on twisting forces in corners. The biggest improvement would likely come from adding a small swing link to connect the seat stays to the front triangle. Your shock will thank you for it 😅. From there, you could increase rear triangle rigidity by adding a seat stay bridge. If you want to take it even further, you could beef up the chain...

I don't remember the video from Nekko but it shouldn't be the dutty of a consumer to prove what your product does. And yes, for some reason the mass damper products seem very data driven so for once we may get a product that is actually back-up which is cool. At least you will know what you buy, why you...

There’s definitely data out there if you look deep enough. I guess there’s many consumers who don’t care about the data and just want something that’s cool? Hopefully with new technology, it will be easier for brands to gather, sort and analyze the data. Neko Mulally had data when testing oChain and said he saw a change in dynamic sag. This was in one of his earlier videos when testing between the high and low pivot bike. CounterShox had data showing with and out their device showing a clear difference.

Placebo effect is not too hard to prove or bust, have a double blind experiment. Put a series of riders on bikes, with or without the ochain and ask them how they liked the performance of the bike. In order to account for the pedal feedback you could tell them they are not allowed to pedal and have the bb...

We can go a step further, lace an Ochain onto a spoked crankset and use the new Lauf freehub system mixed with the e*thirteen sidekick system, over 30 degrees of supply, spongy chain engagement so that when you hit a bump your pedals actually kick forwards driving the wheel even faster! Effectively you have the same degree of engagement as a crank Brothers hub from 2011! 16 poe of goodness

Whoa whoa whoa don't go giving the marketing people any idea's like that. Soon a 45mm stem will be marketed as 10% more compact than a 50mm stem.

Same goes with all the pedal kick dampers (Ochain and Rimpact, e13 new hub). For instance, did you ever see a graph, data, anything that shows in which way does pedal kick dampers actually do anything ? Yes riders tell us it does something, TEAMROBOT did an excellent video about it too. But these companies should be able to quantify...

So there’s evidence people have been looking at, thinking about, measuring and comparing bike component compliance for years. And there’s evidence that some component and system (for example, a wheel) makers have been doing the same. But instead of helping to create basic language and tools riders could use to compare compliance as one more factor to consider alongside all the other bike fit and performance details, every company is mining the compliance boom in the same way. Our new gen widget is more compliant (but not too compliant!) than our previous gen widget. Start tuning your ride today! Marketing...

17% isn't much but compared to most single pivot on the market that have 0 to 5% of progression this is a lot lol. As an enduro bike I wouldn't change anything on it really. As a DH bike I would use some slightly shorter chainstays (460 or 465mm) to help a little in the very steep stuff and add...
This much ! So slightly more than 17%. I ride the bike with 32/33% of static SAG and a lot of compression. Makes is super dynamic and poppy (especially with the mid stroke support of a coil shock), not the best at ironing trail chater tho, and I don't have any issues with bottoming out even on big features. So...

Yeah its just a lot of complication and I'm sure cost that's just unnecessary. Seems like we have hopefully moved away from the engagement wars from a few years ago. Everyone was racing to see who could have the highest engagement hubs and in reality on the trails after 36 or so POE its hardly noticeable.

This is basically a different category though. Turd product for real mountain bikers but this is for the retired $10k+ e-bike trekkers who want suspension for comfort. Those bikes are high end in their own lane so the fox branding makes sense.

I think they’re trying to do two things with the brand simultaneously. They’re trying to position it as the cool freeride brand with things like the Bomber DJ, the 58 and Super Z. But they’re also trying to create an offering to compete with the ultra cheap RS offerings in the OEM space (like the 35 Gold and Silver) without devaluing the Fox brand image.

I should add that the bike rides very well and is very dynamic (more than my previous GTs Force 27.5 and 29). The only moment I notice the lack of rigidity is in pretty high load type of berms, so the question is, aside from how to make it stiffer, is it worth it and could it make it worse...
I realised I didn't have any picture of my bike (after 2 seasons lol) so I took some this morning. The bike has heen welded by Egerie in France, based on a linkage file I made. The idea here is to have the chainstay length based on a front to rear center ratio. I checked that ratio at SAG on...

I also ride a custom steel frame. Mine is single pivot with spherical bearings on the shock so the rear end is quite compliant. I ride it on every type of riding. It excels on off camber chunder and will hold a high line that other bikes won't. This matches the USD Dorado fork quite well. G-out berms/ruts are it's weakness and I can feel the wag if I load up in the corner. I find that the wag in corners becomes intuitive and you get to know the bike in consistent berms. Harsh g out ruts that change lap...

Super interesting thread ! I am currently riding a custom made steel frame, superenduro/freeride type. You thread comes just as I am considering frame flex on my own frame as I noticed some after riding it harder and harder. Basically I noticed that my frame flexes on high side load situations, mostly high G berms. Initially I thought it was...

Hey, I’m Ryan Burney. I’ve spent eight years as an engineer for full-suspension bikes, working on some fun projects, like developing the flex Horst link for the Cannondale Scalpel and being lead engineer for the latest GT Fury downhill bike. With over a decade of downhill racing under my belt (even made it to one World Cup—though I didn’t qualify so I stuck to engineering), I've had the pleasure of racing alongside the Vital crew, like Jason, Tanner, and Dak. Below is a photo of me, being slower than Dak. These days, I’m focused on my own projects, but I...
