I got an old mangled Di2 mech here, I might see what the minimum current would be to get it to move about, however it may need signal. I reckon a couple of CR2032 batteries in series would get it going, total weight.... 5grams?

That's pretty cool tech, thanks! Seems to have the same problems as a dyno hub tho; requires a special hub and a way to distribute the power to the component that need it. I wonder if it can be made small enough to fit in a jockey wheel/derailleur cage?

In the angling world, Shimano has what they call "DC" braking for baitcaster reels. It's basically a tiny magnetic power generator that also uses the magnets to to activate braking during a cast (to control line speed.) You can watch a short youtube video explaining it here. My guess is something similar could be possible by using the rear hub to power a rear derailleur, after all, you only shift when you are moving. This is just a guess though, as I'm no engineer.

Know these have been spotted already a few times, but I noticed in the latest PB rampage video that the proto hope levers were actually labeled tech4. not exactly a revelation but interesting either way.

The [large] shop I worked at made most of its money off of bikes [hybrid/urban, mountain, road in decreasing order], although clothing and accessories had better margin. Service work was effectively break-even [lots of free tweaks and adjustments for existing customers] and margin on parts is terrible. Online sales were fairly small when I started there, about the same revenue as 1 full-time salesperson, but with lower margins. Even before the pandemic, online sales were ramping up, but once April 2020 hit... I can't recall the exact numbers, but online sales quadrupled [more?] overnight, margins improved, etc. It's become...

you know your little site is making it big time when the companies you write about comment directly on pages about their own work.

A hipster? Really? I'm truly offended now

i think its a cool piece of tech, and wouldn't mind throwing a leg over a bike equipped with it to try it. in terms of racing, i certainly get where your coming from where the bike is doing something automatically being an enhancement. it'd be cool to see some testing to see if it would actually provide any benefits on the clock. it would have to be conducted as a controlled blind test - same trail, several riders, and several identical bikes equipped with and without axs suspension. you might need a really loud hub or something to prevent...

I see it from the privateer eyes.. does not help to level the field.. bunch of factory guys with AI built in their bikes and others struggling to get super freshly service forks for the race day.. i dont know, dont get me wrong, I like the engineerding of it.. and today you have data acq and custom tuned suspension, some teams have the resources for it and others dont, may be its the same.. but come race day , they should all be sort of leveled, manual lock outs? You still need to trigger it with your finger.. active...

Nice Podcast with blister Dan, .. I am totally inclined to think that these things cannot be allowed in racing. let's see what regulations end up being.. geeking out is cool and all but this has no place in racing disciplines..

Yes. They no longer allow electronic suspensions.

It is my opinion that electronic suspensions have no place in racing. I'm all for engineering marvels and recreational use. I think we should take note from other racing disciplines that have removed the racer from the equation and then reversed course.

Here's the full post on Sik Mik's retirement via his team: After an incredible 20 years of racing, the legend of our sports Sick Mick Hannah announces that his last World Cup will be this weekend in Snowshoe, West Virginia. Mick’s first elite mountain bike race was in Maribor in 2001 where he finished 6th! He stood on the UCI World Cup podium 17 times with one victory, scored 3 medals at World Championships and 16 Crankworx medals! Here are Mick’s words: “The time has come to announce that I’m retiring from World Cup racing. This is a...

graves on yeti ebike at EWS during shakedown laps, clearly trying to hide the important part LOL

The switch kinda thingie part in the suspension comes from the vertical link pulling the lower link up until the vertical link passes past the main rocker pivot, after that point the lower link should start rotating back down. Therefore a similar behaviour as the switch 4-bar suspension systems.
