Telelever (trellis) suspension on mountain bike.

It’s really closer to a pure Hossack design than Telelever, but the way the wishbones/trailing links are used to transmit steering force is...different.

ooh, cool! what are the advantages vs having the suspension on the fork?

It is Hossack who did it. Close yes, and interesting. I’m fiddling around with how this could be designed into a cross/comuter frame, both front and rear so the wheelbase and fork rake never changes.

supposedly removes the forces of suspension from steering inputs so no one device is doing everything.

makes sense, so it’s meant for less strain under heavy riding?

In days of yore, I drew up a dual-trailing arm rear suspension for a motorcycle (in part to get a virtual swing arm pivot which was coincident with the drive sprocket). I bet with the right degree of anti-dive, but with the arms inclined (maybe?), you could get something close.

I predict the headset bearings will last......this long.

From the little I’ve found on it, it comes from motorcycles where the weight under braking compresses the suspension, using this style of suspension increases pneumatic trail and other geometry under compression and gives more stability to the rider.

Can I ask why any of that is necessary on a cyclocross bike?

Look at the Cannondale slate. Im thinking of a short travel FS version

I’m speechless, that doesn’t seem necessary at all. One site had it listed as a Gravel bike, I’m surrounded by gravel and suspension is completely unnecessary for it.
If you want a bike for all surfaces, look at a Salsa Warbird or other bikes from Salsa, you can throw 40c tires on the Warbird and they’re proper 700c tires so they’re more commonly available.

Oh I understand that. Gravel grinders are wonderful things, but riding my cross bike out here on gravel roads, there’s always an extended washboard or rutted section or surprise hits that at least a fork shock would be very welcome with, even if i’m running my tubeless tires at 38psi race trim (im not a featherweight). That Slate uses 650b wheels (smaller than a normal cross or grinder 700c) with some 41 tires making the actual diameter the same as a 700c with 22 or 23’s. The benefit is great acceleration, awesome ride grip and damping and with that fork, you can now take some hits and get more agressive. C’dale bills it as an adventure bike. So it’s, in a way, a very lightweight MTB not meant for drops but for atacking rougher logging and fire roads.

Why not run 41c Clements on your cross bike and have a better ride? Why go down in tire size for no reason? It’s a 38mm diameter difference, the weight change is negligible. I just don’t see the argument for the Slate’s wheel choice, especially when Salsa and others are running 40c+ tires on standard 700c rims.
The telelever fork has me doubting if it’s beneficial on a bicycle, for a motorcycle it makes sense because the higher speed and higher pitching moment compresses the fork and with the telelever arrangement it creates more pneumatic trail under dive and more rider control/confidence, for a bicycle I don’t really see the diving moment being generated to make that geometry change useful.
