It took 17 hours for a Turner Homer to mention pivot bushings… What a time to be alive.

I replaced my shock end bushings with needle bearings and the suspension is just smoother. Been done on 3 different bikes, but all Crab Link so may be different with other suspension designs.

Any idea what they are improving with the new 36 chassis? The 21/23 chassis hasn't been around for long, has it?

There are photos earlier in this thread of the new 34 being used an XC race. It has a conventional arch with sections removed for a more conservative generative design vibe than the new 32. I expect the same thing for the 36.

Dave Turner had bushing on his Turner Bikes and they worked great in Austin (mainly dry riding and plenty of creek crossings). I had an O2 and 5Spot which were some of my favorite frames.

Was gonna post about my Turner bushings. Was not a good choice in the muddy northeast. Worked fine when fresh and clean, but I was taking apart the pivots for a clean and grease every month. 

Sick bikes anyway. That 5 spot was 15 years ahead of its time.

Back to rumours : a major suspension player is making USD fork

Bumping this spicy rumor. Hoping more gossip to be teased about it. 

Hearing it's Cane Creek, a big travel enduro fork.

Did Canyon just drop something new.

Or am I just that uninterested in them that this has previously passed me by:

Oh right 😂

I don’t follow FMD either.

My disinterest has in both is stronger than I thought 😳😅

Not continue my digression any further, but I am a Tahnee fan. I still missed all the Canyon hype, so I'll blame the almighty algorithm for that. I get mostly mechanic stuff, F1, Brandog, MB Cyclery with a healthy dose of bee_kay77 and watchcwgo.

I'd love to see what Tahnee could do away from FMD. In my biased opinion it worked incredibly well for the Athertons but not so well for her... Maybe it's because mum and dad weren't part of the team.

Bushing require tight tolerances and proper maintenance. 

The cycling industry is crappy at tight tolerances. 

Most cyclist are crappy at maintenance. 

It's a win win resulting in the horrible reputation that bushings have.

Like press fit bearings, they are the correct engineering solution. But that would require the bike industry to stop being crappy.

Interesting that Luca has a big ass Boa logo on top of his helmet. I don't think I've seen Boa do individual sponsorship deals like that.

Boa sponsors quite a few individual athletes as well as teams.

I didn't see him on those pages but they picked up Jesse Melamed not too long ago...

I'll stick to Horst link. Gotta take a loan out to do a full bearing job on that 😅

 

Very cool stuff though. I saw their belt drive stuff when the Gates guys were out at Outerbike Crested Butte earlier this year.

Super interesting! Seems to me like it's functionally the same as the new Demo prototype, just packaged differently. Axle path controlled by four bars, with a two-force link and an extra rocker to drive the shock. Also quite interesting design of the seatstays. Seems like they're still very much minimizing unsprung weight

The leverage that is being put on the upper elbow of the silver swing link from the black pull link looks really high.  I've never seen anything with that kind of geometry.

As i aas dreaming of new bikes i went on nicolais website.

Apparently the g1 gearbox bile is mot to far away, you can chopse it as a option in the frame configurator. Unfortunately i cant go through the customizing pages regardless of what frame i chose so i dont know if one can order allready.

This exactly. I can hear the bearings groaning from here. 

Otherwise, as stated, it's a linkage driven Horst link and to me it looks like the name of the game was to make a 4bar work with the existing front triangle by adding just a single pivot point (for the rocker beneath the seat).

My brain can not understand how that thing works.

It looks like very minimal unsprung mass, but a LOT of sprung mass with all that links, bearings and axles (plus the gearbox),  doesn't it?

Anyway, stoked for the bike, for Gamux, for Reece and I am really looking forward to watch them in action this year

This is the (Horst) linkage, defining the axle path:

This drives the shock:

If it's the same colour, it's a single piece.

The chainstay of the horst link has an extension, to which the red short link attaches and pulls down on it to rotate the silver rocker, driving the shock.

Polygon with a new e-mtb?

suspension looks to be the same CBF that Revel is also using?

Not cbf, it's counter rotating links.
