Sorry for the attempted re-post. Didn't realize your page was private. Feels special. It wasn't a hot tub pic, so it caught my attention. 😉

Someone would trust this guy with anything related to suspension? 😂🤡

One of Vital's biggest misses IMO

Well the bad news is that I don't know what to tell you, and the good news is that I have nothing to prove, nor nothing to gain for convincing you.  I have a lot of mountain bikes and so does my wife, 6 between us.  Everyone of our bikes has sram brakes with metallic pads, 200mm hs2 rotors and the same sram drivetrains and sram dt350 hubs on every wheelset save one.  There are two extra floater wheelsets between all of the bikes.  

I think it may actually be more important for me to be on the right tires then it is to be on the right bike.  For example, my trail bike runs dhr2 f/r, my wife runs assegai/dhr2 f/r and the floater wheelset we have between us is disector v2 front, forekaster rear.  

Maybe I'm the weirdo that mtb marketing departments are successfully targeting, 

5 bikes between wife and I, and yes I agree with every word this guy says. All my rear wheels are 148 boost axles, makes it easy when....

1. One needs to be trued/serviced

2. Rim cracks at the bikepark

3. Biking trips I just bring an extra ready to go rear wheel

I will also likely never own anything superboost, and if I get a DH bike I'll find one that's on 148 (frameworks/forbidden etc.)

Definitely, agree. Learned some hard lessons between my wife's bikes and mine during weekend's at the park and we only have 3 bikes between us. Having consistency between trail/enduro and DH bike is very nice when shit inevitably happens. It also frees up some space in the van/car, because you don't have to bring a bunch of different parts. Brakes and wheels are nice to have as common parts between the rigs. It also makes it easier to stock those little parts that may break or go missing.

I thought it was very brave of Ebruner to be vulnerable and share how many bikes he and his wife have. It can be tough to come clean.  

We’re all active or recovering bikes addicts here, and this is supposed to be a supportive community for recovery. Or enabling rationalizations and fostering codependency, if that’s what you’re looking for. Both, really.

Guilty. Active. No need for recovery as I’d prefer further addiction.

Fingers crossed they go back to 148.  Some of my favorite bikes were Evil, but I switched to other brands when they went to Superboost.  As someone with multiple bikes, and having been on riding trips where people had to borrow rear wheels, Superboost is a dealbreaker for me.  My current trail bike is a 2022 model, and I haven't been interested in any new bikes.  If Evil goes back to 148, I would probably order one at release.

On trips you can borrow dh wheels from someone or rent a dh wheel from a shop, not the end of the world, although back to 148 would be nice given that transmission offers a similar chain line they wanted to achieve tanks to superboost ( as per one of the last q&a s on instagram )

This is crazy. Who do you know that has spare 157 wheels laying around?  Shops don’t rent wheels. They barely rent bikes anymore.

I was also so thrown off by the comment that a shop would rent a wheel... that sounds like an easy way to go bankrupt if you ask me. I wouldn't want to rent myself a wheel. 

My wife's mom wants to pass on her like-new, lady-riden, 2023 Devinci Troy, which by all means is a sick bike. What keeps me up at night is that it has superboost and doesn't vibe with all our 148 bikes.

I'll add to the dumpster fire: In 2022 a friend of mine broke his super boost rear wheel just days before our bike trip to Moab. He was unable to find any replacement in a big city like Toronto. Not even the shops in Moab had one. After much research. he managed to find a bike shop several hours out of the way from Moab that had one collecting dust. If this was a "normal" 148 wheel then he could've used any one of our spare wheels. It's just silly. 

Also never heard of renting wheels in North America.

I've said this before, and it's partially a self inflicted wound, but I own 4 bikes and none of them share wheels.

Stooge- Boost

Knolly - Super Boost

Urban Arrow - old school 135

Moonlander 2.0 - 197 full fat

A few months ago I sold my Chamois Hagar, running classic 142. 

Realistically, all of those bikes except the Moonlander would be well served at 148/Boost. Knolly uses superboost but there is absolutely no reason it couldn't be running regular boost. Gravel bikes are getting there because the commonality with MTB parts does them good.

I had to reverse image search this to make sure it’s not ROBOT. Looks like you dude!

Rental DH wheels?! Im gonna tell that guy who wants to open a mtb shop from the other post…sounds like the perfect move. 

six mountain bikes is too many, but I get it. It’s the seven interchangeable wheelsets that’s untenable. If this is an addict situation then seven wheelsets is a relapse!

Six seems like an aggressive number, but I'm halfway there. Enduro, single speed hardtail, dirt jumper. If I had my way, I'd have a dh/park bike and live where it makes sense to have a fat bike (but definitely not my jam). Plus a gravel bike which I ride the most.

Well there you have it. New business idea: superboost wheel rental. No competition. Charge the full price of the wheel as rental price fee. Rent it out twice you made money lol…

If y'all have to settle keeping bikes with 157 rear hub, E13 is and has blowing out rear wheels with 157 spacing. I almost want to buy the wheel just for the carbon rim.

I feel obliged to point out that pinkbike has an article about SRAM patenting an air based high speed rebound damper.... I've always been skeptical due to how much air A) compresses and b) heats up but interested to hear more informed opinions...

The patent description is quite interesting. Seems more like a way to modify spring rate in one direction only than what we would typically call "damping," if that distinction makes sense. (Cue the semantic arguments!) Vocabulary aside I'd be interested to know what it feels like.

This is the best meme I have seen on this site since I joined.
 

Currently have 10 bikes and 3 project frames in the house that I'll get to at some point in the next 15 years of which 9 are mountain bikes, and two of the ones that aren't are technically mountain bikes.

Didn't Noleen have some sort of air damper back in the K2 days? About the amount of time ago a patent might expire? I may be completely wrong on that as my understanding of suspension at that time was pretty limited.

I can't be the only one thinking 6 bikes between 2 people isn't that many bikes?

1XC, 1 Enduro, 1DH, X2 people seems pretty well rounded. Maybe swap a longer travel trail bike for the Enduro.

Hey look what I found in the parts bin:

IMG 1027.jpg?VersionId=ZQtV4MfP

 

IMG 1028

 

This was one of the last things I worked on at RS before I left...  goal was to control big hits by weakening or slowing down the return of the air spring.  I run my setup with a lot of spring and no damping, so getting bucked on big hits is part of the deal.  

This thing 'gulps' all the air in the positive chamber on compression and lets it out with a tiny delay (since it all has to go through the tiny hole to get out).  No delay on compression- there is a shim check valve that lets air pass in those 4 big holes on the bottom.  Also nice is that it only really affects large hits- when you'd want a bit of help controlling the fork return...  Smaller hits don't fill the chamber with enough air to make a noticeable difference.  So full speed return of the fork on chop and braking bumps, but a bit softer return on g-outs and max travel events.  It rode well.  

Only bad thing is it takes up a token and a half of volume to a Zeb which already needs 0 or a "noken" extra volume thing.  

 

No clue if it's going to production or not.

 

Edit:  Official name is 'the wiffer'

Cane Creek had the Cloud 9 shocks, no oil at all. RST had the Aerosa forks also, an all-air cartridge with adjustable rebound control. 

Spoiler alert: air heats up with successive compressions, so your damping gets temperature dependant.

We're back to the nineties baby!

And there's the informed opinion. Did it work? Beyond the volume issue?

It works on a dyno and I thought it added a benefit to riding.  Obviously I'm super biased though.

I will say- it was a fairly large pain in the ass to get a patent pushed through the right channels at SRAM, so that effort should show we thought it was a good idea.
