It does look pretty BALLER

I really love these projects, especially because they always prove that "retro" colourways still look great on modern frames.

Every time, they make me check what the current colourways are because surely I just don't remember how good the modern colours are and no every time the retro colourway wins.

 

Oh and RM should build that alloy Pipedream bike with the linkage plates.

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?

Ah gotcha, yeah I was way off. Further solidifies my ethos of "don't upgrade droppers" lol.

More details on Reverb AXS - https://www.vitalmtb.com/news/press-release/all-new-rockshox-reverb-axs-dropper-post

Highlights
- Wireless, integrates with AXS ecosystem
- New 'air-over-air' design
- New 'ActiveRide' built-in compliance
- Two-bolt saddle clamp for round/oval rails
- Uses same AXS battery, charger, and controller
- Travel options: 100mm, 125mm, 150mm, 175mm, 200mm, 225mm, and 250mm
- Seatpost diameter: 30.9mm, 31.6mm, 34.9mm
- MSRP: $ 549 // € 600* // £ 535* // AU$ 945* (*includes VAT)

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 Wink  

Any chance you could measure/confirm the stack height of the new Reverb to see if what Robot mentioned (stack being measured to top of post, not saddle rails) to be true? It's odd/annoying that all of the seatpost manufacturers have not agreed upon a set of actual umbers and measurements to make on their posts.

I can just about fit a 210mm OneUp on my bike, but it's almost slammed (maybe +5mm). I would love a 200mm Reverb but given the simplifications that it comes with (and if it reviews well) I would consider dropping to a 175mm post to gain access to those benefits.

I now see that they actually have a fitment calculator on their website: Calculator | RockShox

Looks like a 175mm post for me, if I get one.

I dont understand how that works because according to there calc I can fit a 200 dropper but right now I have a 160 one up and its maxed out.

Literally went away from Reverbs cause I hated that play and losing what felt like a cm or two when I sat down on it, and now they’re advertising it as a feature lmao. We’re riding on suspension bikes but now we need suspension in our seat post too? No thanks.

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.

image 252.png?VersionId=gZ2rOpuZi

 

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.

Apparently I'm one of the lucky few that could fit it - 445 long seat tube with a 320 mm max insertion and my saddle height is at least 810 (that was on 175 mm cranks, might be even more now with 165 mm cranks, depending on the pedals and all) and the calculator it might fit.

Bird's Aeris line has nice and straight seat tubes almost all the way down to the BB.

But I'll be sticking with my cable actuated 240 mm Oneup.

I mean, that's true of almost all welding now though. The I G in TIG and MIG mean inert gas. Sure you can weld steel without it, like with oxy acetylene welding, it welds better with it.

Why would you trade a 200 OneUp for a 175 mm Reverb? It makes no sense to me that losing 2.5 cm of drop, having a battery I can hit my knees on, and spending $$$ is worth getting rid of a cable.

Wireless droppers seem like a huge compromise. Longer overall length for the same drop as the market leading cable posts but the advantage of one less cable. I think I will stick to the cable post thanks.

"Side entry battery" on the new Levo - Does this mean that it has a removable battery?

 

Would be ideal to me, since those full power e-bikes are just above the weight limit of what my bikerack holds (is probably OK, but dumb to take any chances) - And I store the bikes in a cold shed all winter, and its not very fun bringing an several month unwashed bike indoors to charge it in winter. Removable battery would be perfect for both those reasons

I mean... the current Levo battery is removable with a 6mm allen in about 30 seconds... a quicker system would be nice but I wouldn't call it not removable as-is.

The better feature for you sounds like it will be the new charger. Pull your battery and put it on 80% mode for the winter. Giant has been including that feature in their admittedly flawed chargers for quite some time.

SC Syndicate on IG testing a new air spring for the Fox 40, I would guess this has the same changes as seen on the 36 and 36SL to prevent binding under side loading. Likely coming to the 38 in the near future also.

Looks the same as the current one just with a different lower plate assembly, possibly shorter to give a larger negative volume.

Your URL hackery is weak, son.

I have no single idea what the shock could be. Fast? Chickadee? A non-shit x-fusion?
