Oh good I'm not the only one who saw those cranks from NSB and went... "I have seen these before" haha
I gotta imagine the final design will be a little sexier and we are just seeing a proof of concept so to speak.
I seem to recall seeing a bit of a tease about these maybe a year or so ago, so I actually wouldn't be surprised if the cranks pictured are pretty close to a final design. It looks like Lewis Buchanan also has them on his Range right now actually.
I was still in the development stage back in 1992, so I don't really have any opinion on the old RF cranks. Bearing that in mind, I kind of like the utilitarian raw alloy look on those cranks.
Yesterday I saw a SRAM crank with a hole in it. Similar to those MUSA fancy pants cranks. Assume it belongs to the new AXS drivetrain, anyone know anything more?

Please go take your Tesla discussion elsewhere. We aren't interested.
Onto tech rumors: When out on a lazy sunday ride yesterday, I came across a guy on my home trails who had what I can only assume to be a prototype bike with him, painted or wrapped in a black and white digital camouflage pattern. The bike had the unmistakeable silhouette of the Propain Tyee and Spindrift and since Propain is a local-ish brand to me, it's probably safe to assume that it was in fact a Propain. It definitley wasn't an e-bike, but a mountainbike, and since the Tyee is the oldest bike in Propains line-up, I assume that what I saw yesterday was the new generation. I'd say the frame was carbon because it didn't have any obvious welds. It looked quite finished aswell, so the release date might be not too far away.
Anyways, take it with a grain of salt. I only saw the bike for a couple of seconds while the guy took off his jacket and helmet and loaded the bike into his van. It could just have been a regular Tyee or Spindrift with a very eccentric paint job.
There was a blow-out sale of 20 or 25 % off specifically for the Tyee in decembre or over the holidays. And it was only for the Tyee, no other models were discounted.

Yeah talked with a sram rep about them it’ll be the cheapest crank option for the new axs. I think they are going to be rs or something, sram is changing up they’re naming scheme for the new stuff. xx is top end and that’s about all I know.
Also all the new cranks are the quarq 8 bolt direct mount instead of the old 3bolt direct mount.

Some good intel, I love this place.
This one definitely had XO etched onto the crank arm, it looked production quality. It also appeared to either be direct or 4 bolt and had a built in bashguard.

There is possibly a 4 bolt spider available but I have seen the cranks and the main interface at the spindle is the Same as the 8 bolt road.
I must have had it wrong on the names, oops. They look sick though!

I think it was through November as well. Made selling mine even tougher, considering the limited visibility Propain has in the US. Amazing bike and I would definitely be interested in an updated tyee with better cable routing.
Now...snapping square taper RaceFace cranks and the BB spindle simultaneosly...that's doing something.
Or a set of 175mm FSA's drilled as 165's on a giant, brittle ISIS BB with bearings squirting out the sides. You probably did get to torch that combo.
The big bragging right was to bent a high end set of XTR cranks on their original spline BB. Then you could say how expensive your mistake was.
Worst of all was being able to give a set of incredibly sexy rainbow anodized Kooka cranks a sideways glance from across the parking lot and watch them shatter in your mere presence.
Which ironically...isn't even that long ago.

Man...we've got it so good tech wise these days.
How about a set of bent and cracked Profiles? The first time I rode the original Aptos jumps, no one told me you had to hit the second jump like a spine. "Flat" bottomed on the third lip. Welded them up and ran 'em for years after. You can't do that with "Forged." aluminum. Oh, and I'm still running my clunky XTR's on my Hunter.

Yes, that could be another indicator that there's a new generation Propain Tyee right around the corner.

I had two rare sets of Kooka cranks as a teen. I had the blue acid fade and the Camo cranks... Yes folks it doesn't need to be oil slick lol.
Later I found out the guy we purchased them from at a bike parts expo thing who said he was a sales rep for em actually was a part of theft ring of bike parts from delivery trucks.
Sold those cranks for some proper good money on eBay later in life.

Based on the clever way they're approaching this, I think this could be a major step forward in removing the drivetrain mass from the unsprung mass.
My guess would be basically the same current setup, but with two opposed-direction DH-sized cassettes; one on the crankshaft and one on the jack/output shaft and some kind of wizardry that moves them into the proper ratios. At the extreme ends, two X01 DH cassettes would give 576% range... (24/10)/(10/24) = 5.76.

That's kinda what I've gathered from the interviews I've heard. Just super curious about that wizardry!
Hopefully someone will come out with a functional gearbox that just bolts to the motor mounts on an ebike or something. I don't want one (very happy with function and reliability of modern drivetrains); it would just be nice if the "gearbox or die" people would crawl back in their caves for a while.
Two DH cassettes will have massive jumps between the gears for that range. At 500 % range and up, you need at least 12 gears to make it work. Yeah, there will always be some people that will say '9 is enough' (or 7 in this case), but in reality, jumps between gears above 20 % are not a fun thing to have.
To make a back to back cassette gearbox work, you need to have 1 teeth differences between sprockets on each cassette. 2 teeth of difference (for example 11-13-15 etc.) gives 516 % range but 25 to 30 % jumps between gears. With 1T jumps, you need 15 gear pairs to get over the 500 % range threshold (two 11-25 cassettes).
While this is still packageable inside the frame (Honda's practical cassette and derailleur in a box approach doesn't work for modern 12spd 10-50+ cassettes), I do not see how Trinity's approach of moving the cassettes, but not the chain, will work when you have cassettes that wide. You'd need a whole lot of space. That's why it's also VERY interesting to me that they move the wider component (cassette) side to side, not the narrow one (the single ring on the other side).
This is why I'm very interested in how they make it work

Agreed on the jumps being too high for the masses relative to current 12sp setups.
However, maybe it's the singlespeeder in me, but I love the idea of the huge range with big jumps and minimal number of gears.

If you move the cassettes one at a time you would have 2x the number of speeds on each cassette. EG two 7 speed cassettes would work out to 14 speeds.
This would actually make it much closer to what Shimano patented. The patent covers moving the chain over the back-to-back cassettes with one of the cassettes moving left and right by one sprocket to increase the number of gears.
I seem to recall seeing a bit of a tease about these maybe a year or so ago, so I actually wouldn't be surprised if the cranks pictured are pretty close to a final design. It looks like Lewis Buchanan also has them on his Range right now actually.

Looks very similar to Canfield cranks.

Commencal coming out with a gravel bike, frame probably alloy, taking bets if the fork is going to be carbon or not
Trinity MTB has their derailleur in a box ready to test.

Really wondering what their wide range gearbox will look like. Supposedly something is in the works.
Yeah, really curious how they're going to pull that off.
Based on the clever way they're approaching this, I think this could be a major step forward in removing the drivetrain mass from the unsprung mass.
I like what trinity is doing with the BB area mount that can work for normal/e-bike/gearbox etc.
seems like a design standardization here could make a lot of things compatible.
