The following example is comparing three different theoretical bikes that have the same travel and progression, but different shock strokes. I made up a function to depict the air spring. It's not perfect, but it's not far off either. More ramp that most air shocks. This is only a portion of the picture. I wouldn't say there's any benefit to designing a bike around a short shock beyond fixing clearance issues if there are any, though. The reality is there are loads of air shocks that are plenty linear out there. Leverage curves (made them linear functions for the sake...

can we get back to rumors and please keep the headset standard discussion seperated (again)?! thx

Million dollar idea: every frame comes with three headtubes welded in a neat row to the front of it. Users can play around with reach to their heart's content, then use an angle grinder to cut off whichever ones they don't end up using. Or save them all for resale value. Choose your own adventure.

He had that mule last year, too, didn’t he? (judged events don’t belong in mountain biking)

I think its custom made just for him. They call it the Trek Sesh. I think i remember seeing a bit of a bike check on it.

BOS is apparently poised to make a major push back into the MTB market, they have refreshed their entire range of products - it all drops on November 11 but here's the info already: https://www.vitalmtb.com/news/press-release/bos-suspension-launches-bos….

E13 was created by Evil bikes? Dafaq?!?!?! O_o

I am in the engineering department at Push, and we're all big fans of the Vital community! - Matt I guess I should prefaced that manufacturing comment, before I get the "my buddy owns a casting shop and ..." 😂 So for starters there aren't many magnesium casting suppliers in the US (probably because of safety issues 🔥) but funny enough there is one just down the street from us. The problem with most US manufacturers is size, difficulty, volume, and capacity all have to align before they are interested in any new work. In my experience this is fundamentally...

How can we blame the industry for going in circles regarding development if we can't even keep our forum topics straight. This must be the 5th generation of USD fork discussion.

Please buy my DH fork that's been ridden super hard and never serviced. The oil seals don't leak because there's not enough oil left in the lowers to properly lubricate the bushings. If you can deflect a 35mm Boxxer to the point it's truly an issue, I'll be the first one to cheer for you on the WC circuit or at Rampage.

i never posted it here but the slowmo vid from MSA below has some fantastic examples of bikes/forks flexing, especially in the slab section with slow-but-big curb-like hits on the front wheel. rocks start around 4 mins i think. sometimes the forks flex, sometimes the frames do. energy has to go somewhere (and yes, i know everyone wants the fork to absorb the energy through its operation).

Fox. Creates larger air chamber. Fills it with grease. Benefits negated.

Other than the cable ports the front triangle looks literally identical. Credit to taprider on the NSMB forums. Apparently my LBS has them in stock, built, and hidden in the back, but I haven't been down to look.

Hey all, just got this shiny new thing in the mail to test. Rimpact's press release is linked here, along with some of my first impressions before bolting it on the old bike. Obviously it looks a lot like an Ochain, but Rimpact says their device is designed to address a different mechanism of suspension interference. Innovation!

Oh crab, forgot about it, help me out on the correct term? Previously someone called it a sex bar.

Looks to be two new bikes coming from Polygon based on Dan Wolfes instagram. Looks like they’re making a carbon version of the colossus enduro bike (which might bring the complete weight below 40lbs lol). And a new carbon framed e-bike using a new version of polygons 6-bar linkage. Looks to be using a Bosch motor based off some of his POV footage and will presumably use the new Bosch gen5 motor. Pics: (e-bike is the black bike, Carbon colossus is the white one)

What are the similarities and differences between the E13 sidekick and the WRProducts DTSwiss 0 drag internals? If this has been covered feel free to flog me.
