  • Join Anna Cipullo as she tours the ‪@FOXFACTORY‬ R&D facility with Andrew Taylor, taking a closer look at all the machinery that is used to stress test Fox and Race Face components. Andrew Taylor is one of Fox's test engineers who moved over from testing suspension for powered vehicles to testing components for bikes. Today we find out how Fox Factory test not only their suspension but also Race Face handlebars and wheels too. They test the components for lateral stiffness, torsional stiffness, fatigue, and more!

    I find it amazing that all this testing and development is done on the products to make an awesome product. Then all that good work it's wasted by bad assembly process. For example I have a brand new Fox 38 that wasn't riding the best, a quick Google search says too much grease in negative air chamber. Got fork serviced, it was full of grease and transfer ports blocked. Fork is now amazing, but shouldn't need to get brand fork serviced when first setting up

  • @blakekennard7700

    On my HT I’m running a Rockshock Yari 140mm with 35 mm stantions. It seems to ride higher in the travel the way I have it set up to keep it from diving for majority of riding. On My FS running a Marzocchi Bomber Z1 at 140mm travel with 36mm stantions, mated up with a Fox Float X shock in the rear. I had to run quite a bit faster rebound on the Marzocchi to prevent it from packing up and changing the geo. Both forks are pretty easy to get dialed in to how I want them to feel. The Marzocchi is a little more plush throughout its travel which I like on the full sus, seems to complement the Float X very well. Been thinking about volume reducers for both in the future. I’m 225lbs so even though I’m running 140mm travel forks I like the beefier stantions on both, gives a more precise and composed feel.

    On the seatpost test rig, why wouldn't they test thedropper locked in the top position under load before pressing the lever to make it go down again. Pressing the lever in, allowing it to extend and then dropping it again without allowing it to lock out under load isn't representative of real world conditions.

      Exactly this, they can do it but some Excel sheet said that it’s not viable. Funny thing is that they will sell you burnishing tool or do it for you per warranty request if you’re persistent enough. Same goes for the amount of grease in the negative chamber, same problem since 2015.

  • @smithandshortdogs
    @smithandshortdogs Місяць тому +5

    I am kind of curious about the service life on MTB products. I had a 2010 Ford Raptor (the vehicle the engineer in this video mentioned working on before moving over to MTBs). The year I had ran Fox triple bypass rears with front internal bypass shocks. Around 12 inches of travel in the real about 11 in the front. I have buddies with 100000 miles on the shocks and they are still running pretty strong. That is on a 3 ton truck that can do 80+ mph offroad.
    My bikes run a variety of Fox and Rockshox products that have a recommended service life of 50 hours.
    I know it is apples to cannonballs but how are they managing to get such great life out of their automotive products and so little life comparatively out of the MTB ones? Is it a case of the MTB stuff being pushed to the limits whilst the oem automotive stuff is dialed back a little.... like a race tuned engine (on the mtb suspension) vs a tractor trailer diesel (on the oem auto stuff)?

    • @Jean-jk4zv
      @Jean-jk4zv Місяць тому +2

      Would say because of weight. Lighter parts are less durable and need more maintenance.

    • @mattkneller900
      @mattkneller900 Місяць тому

      Oil volume

    • @Ahaggah
      @Ahaggah 29 днів тому

      My guess is that truck shocks will have more, tighter, and more durable seals compared to mountain bikes, which will greatly decrease contamination from all the crap that exists outside, but significantly increase friction. The added friction ends up being meaningless because, as you said, the truck wheights 3 tons, which is 40 times the weight of a mountain bike rider.

    • @rustler08
      @rustler08 28 днів тому

      Well, for one it's the fact that those service intervals are essentially peak performance intervals. You can absolutely run the suspension longer, but performance will eventually degrade. You could have serviced those triple bypasses more frequently and they would have also done better.
      Two, it's oil volume and design. Those forks have to be light so we don't have 50lb+ bikes and the suspension has to not have stiction, because they only have rider weight to overcome it. So, they skimp on support parts

      Nice! Although you may find that a little bit of a service on it has it coming back with performance that you'd forgotten it could get! 5 years is quite a while, but if it ain't broke, don't fix it!

    • @AnotherMrLizard
      @AnotherMrLizard 24 дні тому

      Maintenance isn’t waiting until something bad happens, servicing should be done way before that which is why intervals are set. I don’t see the point in paying top dollar for a high performance fork and then losing said performance by neglecting it.

  • @smithandshortdogs
    @smithandshortdogs Місяць тому

    Not related to the video, but a suspension question on the less.... why do shocks get hot on long descents? I had always heard that it is because the air is being compressed in them.. Boyle's law and all that. This made sense to me until I was doing bunny hops in the street outside my house this morning. If they heat up under compression, shouldn't they cool down under rebound? The expansion off gases coming out of a spray can is what cools it down.... and that is how AC and fridges work. I realise it is not going to be perfectly one for one but still.
    I get that in a vehicles suspension large quantities of fluid are being forced through small holes to create the damping, and that the fluid is heated by friction... is the same thing causing the heating in the MTB shock? I admit my knowledge of MTB dampers is fairly rudimentary.

    • @Jean-jk4zv
      @Jean-jk4zv Місяць тому +1

      Moving molecules generate heat. Compression or Expansion.

    • @andyarchitect
      @andyarchitect Місяць тому +2

      My understanding is its mainly the oil in the damper being forced through small holes at pressure. This generates heat and this builds up on a long decent. That's my some shocks have a piggy back reservoir to increase the volume of oil and reducing the chance of it getting too hot.
