You would think that with an ebike you could simplify the suspension design because you are not as concerned with losses from the suspension as they would be easily picked up by the motor.

You can still get a really nice curves without all the extra moving parts.

It would be interesting to see if there is any truth to that. If someone actually tested ebike efficiency in that manner. I would suspect it to be less that 1% on the life of the battery though in the high power settings unless your are really trying to extend the battery life in a low power application I can't see it being worth the extra complexity over time.

Question for the suspension wonks: To my uneducated eyes the motion and resulting anti-squat, anti-rise and leverage curves of the Yeti 160E's rear suspension look very similar to what you can get out of a simple Horst Link, in contrast to what they've achieved with the switch infinity system. Does it look like there's a significant enough difference to make all of this effort worthwhile, or is it just marketing?
its pretty magical. they have made a complex linkage that moves very similarly in nature to their switch infinity. that classic up down motion that we all know and love. the result is an anti squat that stays insanely consistent compared to other bikes. right above 100 which is why the bike has so much traction, the suspension moves around obstacles when climbing instead of being too firm while pedaling with other virtual pivot designs

This is the bike with the electronic RS suspension something or other...

That addition to the LHS (looker's Right) AXS remote must be the electronic lockout/whatever

i haven't been following the axs suspension stuff that closely, but given what else is being done with AXS i'd expect/hope it would be something more advanced than just a simple lockout. perhaps the ability to run predetermined compression settings?

If you let it go that far you have a bigger problem on your hands. As in it's not the bike that's the problem, it's the rider.

As for e-bike efficiency, I wouldn't be surprised if more gains could be made on the motor/internal drivetrain side of things compared to reducing pedal bob to conserve the batteries. Considering most designs use plastic gears in some way, shape or form.

Then there is also the fact that the e-bike mid-drive unit does not produce pedal bob. Pedal bob is caused by the intermittent nature of a human pedaling, where you have clearly defined peaks and throughs in power, while the motor puts out the power constantly. If you have constant power applied to the rear wheel of a mountain bike, it will just squat and stay there. The amount of squat depends on the amount of antisquat in the system and the power delivered by the motor.

The two paddle AXS lever will probably have one button to control the dropper and one button to control the suspension.

not quite, if I watch my power output on the screen, especially with flat pedals on, you can see it vary output significantly on each stroke through it's peak/trough. The torque sensoring is quite sensitive which is cool. They definitely have pedal bob/inefficiencies, but who cares!

Also, one thing I noticed is pedal kickback is all but eliminated on an ebike, there is a tiny bit of brake jack if you really come into a rough section locked up, but there must be a decoupling in the motor at freewheel (steps e8000) this is something not many people mention but probably another aspect of why these things feel so great descending.

Without the motor, my bike shows pretty crazy amounts of pedal force under compression in linkage x3. (linkage driven single pivot)

One of the beauties of AXS is that you can program the button function to suit whatever components are fitted to your bike. So it could be dropper or suspension or even gears

any thoughts / speculation on the Push Industries fork? that other website had an article the other day as a result of the pic Push posted on instagram. dual crown inverted linkage fork. but not sure that would be the final version that sees production. could be an inverted dual crown trail fork. push likes to make stuff in house, or source as locally as possible. and there is another CO company currently making carbon in house, so there's the possibility we could see carbon uppers.

Assuming they want to use their current air/coil springs I would assume single crown, 140-170mm travel, with 35 or 36mm stanctions. That said pretty much anything is possible.

I know linkage advantage is having less stiction, this appears to still have the bigger seal surface stiction as a regular fork with the advantage of the linkage system. The Push guys rock and must have this working well if they are proposing building this fork for production. Also I didnt see if this was a single side fork or if both stanchions are used. I am intrigued by its design.

My guess is they are 2 Stanchions. How are the mounting the brake otherwise.

how does any other single sided fork mount a disc brake? and btw, this is still not going into production with any amount of legs.

well for one, in the pb article it states that this linkage fork was an experiment and they abandoned it. and two, darren has specifically stated that they are not going to produce this fork. again, rtfa.

Personally don't think they need to change much. Maybe get rid of the flipchip on the shock and add the headset cup and chain stay Geo adjustments they have on the new Stumpy evo. that's all I could think of the bikes amazing as is. Wish there could be more seat post insertion with the short seat tubes but that's just personal preference and don't know if it would be possible with the design.

No new Enduro frame until this coming spring.
It'll basically be the Kenevo SL frame minus the motor.

This spring eh? Sounds pretty specific. I'm thinking of building an Enduro up as I want to move from one bike to two but those are the changes I want, specifically the headset cups.

Other single sided forks have a left hand leg, and you can see the disc on the opposite side from the leg on the pics all taken from the right hand side. So unless they have also developed a floating front brake mount, my guess is it has two legs. Like I said, guess.

Don't quote me on this but I'm pretty sure Spesh has a regimented 3 year cycle life for their frames.

That is pretty typical for Specialized.. However, with the current state of things, I wouldn't be surprised if a couple of current frames get an extra year or 2 added to their life..
