Cduro is prototyping a High Pivot frame, these bikes are quite fascinating in real life, the frame construction is amazing
release tomorrow
I can confirm this is true. So disappointing.
Class 1 & 3 are the same, but with 1 having a top speed of 20mph and 3 being 28mph. I run out of assist (15.5mph) before I run out of gears, I'd love assist up to 20 or even 28. Why is this disregarding land and recreation managers exactly?
The only 3d printer I would want personally and it's not even real
You need an inert atmosphere to print aluminium...
I would tell you to move to the US to enjoy 20mph at the top speed but that's terrible advice these days.
The class 1 and 3 comment was made on April 1st, sooooo I'll believe it when I see it. Also, using all throttle on a 840 battery won't get you that far when Surrons have over 3100wh.
California and the west coast has long been known for having trail access issues. The implementation of e-bikes have increasingly complicated matters in recent years. Our trail advocacy organizations have fought long and hard for more access by building relationships and trust with land owners. Specialized had long been a big proponent of trail access with programs such as Soil Searching until they recently axed the program due to budget cuts. Now allowing e-mountain bikes to go 28mph on our local trail networks will lose the trust of current partners and kill the possibility of opening up new land to mountain bike access. Specialized know this better than anyone with their HQ being located within an hour of Santa Cruz and Marin County, area's where you often see bumper stickers that say, "mountain biking is not a crime"
Probably still better than the dji vpn software update thing to get around your local laws.
I'm not talking about catastrophic failure. Carbon is kind of pain in the butt long term esthetically IMO, and it eventually looks really hagard once enough paint is chipped or worn. An A.L. frame you can just take all the paint off and go raw if the paint gets too bad. I feel like people with carbon bikes always go out of their way to make sure it's not rubbing up on anything, ect. I can deal with that special treatment for short travel bikes, but it kind of gets old and feels weird doing it for a burly long travel bike. I don't mind having a weaker, heavier bike if it's a lot easier to live with, I'm not a pro rider so I don't need to ride the same bike a pro does.
Hunting around and found this - https://www.cyclerynorthside.com.au/2026-rockshox-reverb-axs-seat-post.html?id=111823718&quantity=1 - although the picture is original it lists 150, 175 and 200mm drop options..
I expect you'd also need an inert atmosphere to produce and handle the powder, or some method of pre-process surface activation.
(disclaimer: not my area of expertise)
Nothing screams “claptrap” quite like a stripped-raw production bike that was covered in logos when it left the showroom floor 6 years prior.
And if you’re chipping so much paint off of a bike that it looks haggard due to its paint long before the components become outdated enough for those to be the sore thumb sticking out, maybe it’s a personal problem…
It's probably a Cali-Centric problem, because they put 1/4"-1/2" granite aggregate on all the fire roads around here. You get rock chips from CLIMBS around here if you're not a total squid.
And if you have a problem with a raw aluminum mtb frame, that sounds like a very serious personal problem. You should probably seek professional help with that one🫡
You can tell us that you care too much about what other people are riding.
What's wrong with a raw carbon frame then?
Industrial 3D printers fill the print chamber with nitrogen while printing. Titanium also needs inert gas atmosphere when 3d printing.
The one at work we use has a built in nitrogen generator.
Interesting to hear that some use Nitrogen, I don't know much about the operation of laser sintering machines so I assumed Argon would be the gas of choice.
The new Reverb AXS will come with max 250mm travel!
I assume argon would work but require separate tanks. The nitrogen generator pulls nitrogen out of the atmosphere so you don't have to worry about tanks, just turn it on and let it build up before starting the print. Our laser welder uses argon and metal 3D printing is basically laser welding.
New reverb AXS is up on the red site.. RRP is shockingly reasonable...
Yet stack height of 237mm at 175 drop is horrid
This is a wild guess, but I've been looking at the chart on the website and I think that the 237mm stack height you're referencing on 175mm drop posts might be referring to the entire top of the seatpost, not just the "collar to saddle rail" stack height that we're used to measuring. For instance, I'm looking at the 250mm seatpost and the total post length is listed as 652.8mm, the minimum exposed height is 314.2mm, and the maximum frame insertion is listed as 338.6mm.
314.2mm exposed height + 338.6 frame insertion = 652.8mm, which is the entire length of the post, and doesn't leave any room for the tippy top of the seatpost (the portion above the saddle rails). If I had to guess with my eyeballs how tall that portion is, I'd say 12mm and I'd take that much off that stack height measure. So your 175mm post would have a stack height of 225mm.
Still, at 652.8mm long, that 250mm seatpost is longer than the 26" wide handlebars I learned to ride dirt jumps and downhill on, so it's going to require a special combination of frame and rider to accommodate the full 250mm seatpost
Just for funsies I measured the dimensions on the XL Transition Sentinel I have in for testing and while it looks like I have 400mm of insertion depth, with 302mm exposed from seat collar to saddle rails I'm just short on the stack height to run the 250mm. Santa Cruz doesn't list max insertion depth on my Megatower, but eyeballing it looks like maybe 270mm, plus I run an enormous 347mm of seatpost sticking out of my frame (collar to rail), and that (617mm combined) won't accommodate the 652mm length. So even with my very large 820mm seat height (center of BB to top of saddle), it doesn't look like I'd be able to run the new 250mm Reverb on either of these bikes.
I think it's cool that they still went ahead and offered the 250mm drop post, because it will be a very niche product and they could have easily vetoed it due to smaller projected sale numbers. But some riders will be able to fit it, and they'll be stoked.
For those who don't wanna click:
Price: $549 USD / €600 EUR / $945 AUS / £535
Plus $150 for a remote if you do not have one.
Is that really that good? IDK man.. I have pretty much just rode whatever dropper comes on my bike, I just don't really care to buy a nicer one but isn't like the best of the best cable droppers costing around 250 bucks?
But this one has Active Ride
Bike Yoke Revive, which is the best dropper out there IMO, is $410ish for the longest version, 213mm, does not include the remote. Add in a PNW Loam Lever for ~$69ish...
Seems like Oneup is at 610mm for 240mm drop, so there is still at 30mm ish difference in stack

I've only got 3 rides in on the post ~5hrs ride time. It works great, as it should at the beginning of its life. A few things that have stood out:
- I was reminded how fast the post extends compared to cable droppers. Feels like a pro or con depending on how often you like riding at half-mast, as it can be tough to not get punched by your saddle when trying to stop it from extending.
- There is zero side-to-side play.
- I ride flats with my feet tight to my cranks and my legs are size medium-large knee pad. The inside of my knee/thigh have occasionally bumped the new battery location. Not really an issue, but something that didn't happen with the previous Reverb
- The 'ActiveRide' feature, where the post has ~10mm of travel when not fully extended, has been useless on an acoustic bike. Not that it's bad, I've just not had a use for it. I played around with pedaling a flat dirt road with the post halfway up (or down?) and it did add some comfort. About as much comfort as you get going from riding with your shock locked out to open. It made me wish there was a way to engage the feature with the post fully extended, such as holding the controller longer. I think I'd use that for chattery, fast climbs when you want a little bit more cushion but need to get full pedal strokes.
- It's still expensive, but it is cheaper than before. The obvious benefits for me are that it cleans up your cockpit, it's easy to install, and you don't have a cable or housing that wears out over time/needs replacing every so often. However, I still think I'd buy a cheaper mechanical dropper and save my money for other components. You know, like one of those 3D printed Specialized saddles
