Three gears in the front and seven in the back could be the perfect ratio for mountain biking! It's almost like it would give you three different gear "ranges" using the front shifter- one for climbing, one for descending, and one for everything in between. And the chain alignment could be so much straighter without having to pack all your gears onto one super wide cassette. I wonder why no one's thought of that yet? I can't think of any downsides.

Haven't gotten all the way through yet, but I'm finding this very interesting. Thanks for providing a platform/outlet for this kinda stuff.

I love that chris Canfield is dropping weird bikes all the time now . Titanium DH bikes with gearboxes ? I’m Here for it.

Little insight I got. July release for yeti Avinox cvt system is not 100% and far out from coming to the market. Apparently issues with the system auto shifting down when rider puts high watts combine with motor. Sounds like System protecting itself. Not sure if this is just a software or the system not being able to handle it. We’ll see. Some high ups in specialized are not happy. A nasty email sent to engineers/ product developers to step it up and motor/gearbox combo bike priority 1 Specialized has an unreleased bike the industry will get to see at...

One of the key guys at Banshee also posted on his stories a few weeks ago about testing a proto/new DH bike. Didn't get screengrabs, but it didn't show much. Probably be seen on the MSC later this year is my guess

I could give this a go, would back to back race sim laps be enough to provide accurate results? At least in a way that it is consistently one way or the other?

Dario from PB was riding one at Sun Peaks July 2/3 (think they were doing a field test, saw Matt Beer and Jesse Melamed aswell). He just grinned at the question of how to compares to the old one. Dunno if was anything but I also saw a Banshee DH bike at Silverstar two days later with a bunch of telemetry related stuff on the rear of the bike, not keen enough to have noticed if it was a revised Legend or if it pertained to the rear shock (didn't recognize it)

Let me say more clearly what was implied in my previous post: those old road bike rolling resistance tests tell me that our own internal rolling resistance gauges in our brains are not very trustworthy. I'm not convinced that radial tires roll slower because the only evidence we have is that they feel like they roll slower. 21mm tires pumped up to 120 psi feel fast as hell on asphalt. As you go faster, you get more and more vibration feedback from the tire, giving the sensation of greater and greater speed. A 32mm tubeless GP5000 pumped up to 60...

It wont this year. They made the mistake of designing it without a gearbox. Scrapping the whole lower half of the bike.

Slow clap. Part of the reason why road bikes came with 19-23mm tires pumped up to 120+ psi is because they felt faster than bigger or softer tires, and because of flawed test methodology (testing tires on smooth steel drums in a lab vs. testing on real asphalt). I've heard a lot of people in the tire forum say that radials roll slower, and they certainly might. But until I see actual test results using a methodology that makes sense, I'm going to assume that no one knows the answer to that question.

When do the new Yeti 6 bar pedal bikes drop?

I agree . I’m really really really sick of the constant work I have to do on ALL THE DRIVETRAINS in my family of four’s garage. Yeah they work, 12 speed is good for us, and all brands have little things to help them run better but it’s a heavy wear item and a high cost paddock over here at the moment . 11 year old thrashes everything (sideways impacts) , 13 year old found watts ( and won’t listen to proper shifting “technique”) over the winter, and the wife is a diesel engine just ripping 12 speed chains through...

As of right now, I think gearboxes should be looked at on a per case basis.. Ebikes with MGU, definitely. DH, worth looking at.. Especially if you're not a racer. Beyond those, questionable for MTB.. But, I'm sure improvements will be made..

Everybody serving the gearbox coolaid and how ebikes are getting them and how that will trickle down to pedal bikes, remember that the Avinox and Gaobao or whatever they are called have a CVT gearbox using two electric motors. That kind of a "gearbox" (integrated variable transmission to be precise) is wholly incompatible with bikes that do not have batteries. The only viable gearbox option covering both ebikes and bikes is the Pinion which is, functionally (speaking in volumes), non existent in both camps. As @Shinook and @Uncle Cliffy have said, the future has been promised for years now with...

Long time lurker… longer than I’ve been an ‘official’ member… Phoenix local here… DH tires. Cushcore.. and a Neo Shock. I ride a 2023 Rocky Mountain Altitude and the Neo- has been an absolute game changer for me. I pedal a lot.. and it has made my enduro into a ‘trail-duro’ it’s been a huge innovation for me. DH tires and cushcore so I don’t get stranded in the desert heat and can bash the rocks back.. Neo to pedal all day. I’d recommend it for the type of riding I have out the front door from the house.

Maybe this isn't an accurate point of view, but I feel like pedal MTBs and e-bikes aren't really trying to solve the same problems. I think a pretty massive effort goes into the design of pedal MTBs so that they can be comfortably and efficiently pedaled, at least outside of DH-specific bikes. Even enduro bikes, especially those that are raced, need to pedal decently. For an e-bike, pedal performance is probably pretty far down on the list of design goals. I've watched a handful of folks with dead batteries or faulty electronics try to pedal their 50-lb beasts out of...

FWIW regarding upcoming gearbox ebikes and trickledown to classic bikes, it's a big no. The way these gearbox concepts from Avinox and Gobao work requires an electric motor, so it's a no go for a non electric bicycle. As for shifters, Pinion has electric shifting via triggers and Effigear always supported trigger shifting, but brings it's own problems in regards to shifting with it. Regardless if the benefits it's quite likely the current crop of gearboxes would indeed be a no go for the average rider based on the limitations they bring with them.

Ten years ago, I would have agreed. I don’t anymore. We’ve talked about this a lot in this thread, but bike design, and engineering more broadly, has become increasingly commoditized. Amflow’s bikes are not good just because the motor is good. They are good because we already know what works. Geometry is free, and there is not much left to protect on the kinematics side. I'm not saying there is no gains left to be had, but draw the line. Rate of change matters. They made a bike that is good for most riders, and if they want to go...

"Riding stuff from Asia" is a pretty gross over-simplification of what actually happens to bringing a performance bike to market. I'd guess that the secret sauce for western brands is operating in a core environment that drives product excellence, which translates to a superior product to what non-core brands are able to offer. The Amflow frame, for example, is largely panned over by most and the focus of the brand is on the e-system itself. If that frame contained a Bosch of Shimano drive, it wouldn't have made the same impact. Frames like these are often referred to as parts...
