Agreed, something tells me the dirt and mud that flow into that, aren't going to just flow out like water and air.
They should include a big ass pipe cleaner with the frame!
I'm with Zion-i. Good concept and all...but inevitably water and mud will work it's way in there, then you'll have to pull the bottom to get it all out of there. Without any clear path of escape, not only will it possibly bind up, but there may be excessive wear on any rotating parts as well as potentially damaging the rear shock shaft..
It reminds me of when forks used to have rubber 'boots' on them to protect the stanchions. Grit, mud, and water would get in there eventually, and the boot would just hold it in place instead of allowing it to shed.
the headtube hole leads to the downtube...any dirt or grime is going to travel down the downtube and exit the frame before the bb/under the shock, im sure there is a drainage opening there... as usual more clueless comments on pinkbike...the need for airflow seems ridiculous though, especially including it in the video like its some genius feature.
It looks kind of cool, but I can't really see any advantage of the invisible shock. Also their air flow system really seems to be nothing more than just another marketing gadget. Add 27,5+ and boost to that and I'm not in the least interrested anymore.
What if somebody came up with a frame design that incorporates a shock mounted outside of the frame tubing to for optimum airflow. As a bonus, it might make it easier to adjust the air pressure and damper settings too. I'm gonna try to mock up a design.
It makes sense to me, I'm not heavy and I'd overheat most lightweight inline shocks on some of the trails around here, and that's with air flowing over it to cool it down. It'd be a lot worse confined in a plastic box.
That's a good definition - Designed, not engineered.
Airflow from about 3sq.cm.@ 30km/h to cool an air shock, that is already facing more friction from all the seals. Limited shock options due to the frame design. Opening for the shock adjusters that is just at the place where all of the mud goes to. Able to take wider tires (as if that's not bad but still more mud in the opening) A 5th or whatever's the count new axle standard.
It's got so many wrong's with it that the great design cannot justify. Then again it looks just a if it was designed by DT Swiss - overly complicated solutions to problems no one new even existed.
Oh and it's cables are internal, all but the dropper post - what gives?!
The airflow is the only truly bad thing about it. If you care about shock options, this frame was not designed for you. If you care about being able to frequently fiddle with your shock, this frame was not designed for you. But there's a lot of people that set and forget the shock, and are okay with basic shock performance. Some of them shred hard. One of the best riders I know rides an rp2. Rebuilds it every 4 months, knows his pressures and rebound settings and the only time the shock is touched by human hands is when it's being unbolted from the bike. I haven't changed anything on my vivid air for the past 3 months at least, but I don't think I'd be happy with any inline shock.
If the shock didn't cook itself to death inside a plastic box, I would buy a frame with this design in a second. Provided it had the compatibility/geometry I was after of course - no interest in a plus bike. It looks frikken awesome, and I like the idea of not exposing my shock to dust/mud/rocks.
Seems like a hassle I'm already way to lazy to take out multi tool to adjust my rebound on the cane creek double barrel, looks like i would have to remove a skid plate to do such a thing. eff that noise.
Can we just have normal bikes.
Much like the threaded BB shell, when I look for my next bike I will be buying an "old fashioned" bike with threaded bb and 142 rear axle. And if I buy a 110 front end it better be for a 20mm axle. I think my next fork will be a fox 36 so I can keep my 20mm through axle. And hopefully the good people at Santa Cruz still make these kind of frames in years to come.
I had to watch the video twice to figure out how they get the bolt in the top eyelet of the shock but I get it now lol nice sleek design not sure about that air cooled system they got going on there though but either way she looks beautiful!!!
at first i loved the idea and look of it, but after reading all your critiques i have done a complete 180 on it and think they need to throw this one on the crap pile. Your obvious objections have a ton of validity and need to be seriosly considered before this thing ever sees the light of day.
Wicked design! I really like all the free space that linkage parts normally take away, which is a major feature of this frame. Do we really need shock cooling? I understand that on hot days inside a black frame it might get toasty, but I've never used a shock to the extent of "overheating".
You might be surprised how hot your shock gets. Ride down a fast tech trail that you feel works your suspension, then feel the can at the bottom. You'll find it's quite warm!
But be careful, I damn near burned my calf once resting next to my bike right after a 10 min descent. Coils and big air cans do better, but little Float straight bodied shocks get really hot. Like really, really hot. I'm not joking. It was hot through my glove.
@atrokz agreed. Ive got my RP23 pretty warm, even after long descents with full compressions and mostly 80% compressions, but never hot that I wouldn't want to touch it.
Calipers and disc's on the other hand Burn my leg hair right off!
The scott world cup team uses diposable thermometer stickers on their shocks and said on a pb article that there shocks get as hot as 240F occassionally. So yes, shocks get hot. And if napa ducting is any indication, some frame vents are probably more effective than sticking it in the open air.
The real question, is which songs can I tune it to whistle?
Sweet design but get rid of that awful Boost rear end I'm curious to know how does one tune the shock, what is mud clearance like as well as cleaning, and are you able to mount a shock with a reservoir or a shock with the air can opposite the knobs like on a CCDB InLine?
I want to see some data that shows the mass flow rate of air past the shock is higher than if it is outside the frame, open to the air. And even if you somehow can get more convective heat transfer out of the shock by channeling the air, you still have to consider that it's going to be sitting in an oven baking until you start moving. I can only imagine this is going to result in a much higher net increase in temperature.
What's next? a MTB with intercooler and oil to cool the drivetrain????....come on Switzerland guys... you make the amazing watches and chocolate, don't try to reinvent the wheel with this crappy ideas
Who needs to check sag anyway and 29" to 27.5+? you can kiss your carbon cranks goodbye after running 27.5+ and smashing your cranks into rocks by lowering your BB too much, or is it that the BB is super high when running 29"?
The diameter of a proper 3 inch width 650B tire can equal that of an 2.1 inch 700C tire. So no change in BB height. WTB's first 2.8 width plus tire was deliberately made "small" so as to allow quicker conversions/adoption from existing 29er owners and brands with 29er models, it was not in any way the optimal size to really exploit what's possible.
I love the idea of enclosed suspension due to the fact that I hate cleaning my bike. Air flow...maybe, but dirt and mud are going to get in there which may make for more cleaning in the long run. Overall love the design!!
Wheels too big and a shit hub standard. It's a big fat no from me.
Fancy video though. Especially liked the dramatic glitchy noises. kcchhhhssseeeerrrrPUNK.
Sick looking bike!! Question: how accessible is the shock? Say I wanted to adjust psi or compression or something, how are would it be to get at the shock?
148?!?! Get real DT. How is 1mm off the sides of a 150mm hub change the stiffness of a wheel? Or and extra 3mm on each end of a 'standard' 142 mm hub? What a load of shit.

Also, thank RC that its boost 148. The frame couldn't take the stress of an internal shock otherwise.
