Yes but it only has a 22t, so your suspension will feel that way regardless of the resistance "feel" of the effective 36t.

Dang someones beaten that norco with the ugly stick!
A bad case of curvanitis
<--- This guy doesn't get it. Here's why:
1. It can have the awesomest tensioner in the world and my chain is still going to slap like crazy because the tiny front ring keeps the chain so close to the chainstay.
2. As Skatodd pointed out, you only have a granny ring as far as your suspension is concerned, so like, have fun with that.
3. Extra expense and weight, and you still have a f*cking rear derailleur dangling about.
Why didn't SRAM instead spend two years working on a gearbox or internal gear hub? This seems like a very unnecessary halfway point. Am I wrong or missing something?

you can see it from a different angle there
look quite good. I was expecting the possibility of different cranksets so you just bolt hammerschmidt on spider, bolt some piece on ISCG and run. But it doesnt really matter. Price and durability will be key feature. I will go for hammerschmidt...
Pure conjecture here...
Internally geared hubs are heavy and it would take a whole new frame standard to accept a gearbox. Which isn't to say they aren't working on something, but I'm sure its going to be awhile before we see it.
Hammerschmidt is an interesting idea...I'd like to try one sometime.
closeup shots + internals @ radfahren.de
It looks like they had to put the drive side bearing inside the BB to make room for the transmission. But the left side has the double bearing.
Those parts don't look light, but i wasn't expecting them to be!
I like how it's mounted up to a Scott with the main pivot clearly way above the chainline
OK i know the USA is where Truvativ is from, so why does news like this conme from some German website first??? Is this a press release or did they take it apart? Can anyone translate? Is it that they think the Gemans will adopt the system faster than us yanks? My guess anyway.
The pawls are visible there, due to it's size the engagement may be fairly quick..but my Nexus is similar size and the engagement is far too slow for technical offroad. This may be th biggest hurdle.
That's a 22t ring, i'm guessing that there will be no drag in the 22, but there will be some efficiency loss in the 2nd gear.
maybe its because sram has a german fab in schweinfurt, formerly known as sachs
ill be one of the first to pick one up when they are available. ill be running it on my 29er ss
I am also thinking about making a single speed frame into a 2 speed with the Hammershmidt. I have a 22 - 36 chainring set-up on my cross country bike. I have always resisted single speed due to the extreme grind up climbs. The other day I did a local cross country loop only using my middle (5th) cog in the back and using my front derailieur only. The climbs were manageable in the 22 and the flats and cruising downhills good in the 36. The only problem is that you need a frame with ISCG mounts.
For freeride I think the system will work best with a suspension design with minimal pedal kickback like an FSR or a low pivot single pivot.

So the crank has engagement pawls, would that mean you can swift without pedaling?
Fixie rear hub on my new twin speed?
Fixie rear hub on my new twin speed?
I had a similar thought, but then wondered if it will engage properly in both directions. A "fixie" without the ability to use reverse leg power would be pretty useless IMO.
I was thinking more of the mod. trials bikes that ran the freewheel at the crank for more clearance, plus the chain would always spin for extra street cred.
so...., if they could get 2 gears out of that thing which isnt overly wide, could they devise somethinig that could get like 5 or 6 made to fit on a hub either to replace a free hub or go onto it insted of a cassette? I am not an engineer and do not understand how this works, but is it a possability or am I just way too uninformed?
I'm off for the official launch for 3 days with the SRAM boys starting monday. Should be an interesting product, that if it works as advertised, could have serious potential.
it's the real deal. ive ridden on it albeit shortly i was super impressed
I'll check it out in year two like any intelligent person who likes to finish rides with zero mechanicals would. That's the year when you go by the shop to buy it & they don't have a box of broken bits waiting to be mailed by to manufacturer "X".
I'll take an '06 Sunday please.
I'll take an '05 Boxxer Air please.
I'll take a '97 SRAM thumb shifter please.
I'll take a '99 Shimano DH pedal please.
I'll take a 2002 Manitou Dorado please.
I'll take a 2003 Romic rear shock please.
I'll take a 2005 I-Fly saddle please.
I'll take a 2007 Bobmer ATA please.

maybe works like an enclosed shimano ff system back from the 70s. For the iscg tabs you can always get the adapter e13 makes and put it on your bb.
you can get 3 gear ratios from a single planetary gearset.
they would have to add another gearset to the output of the first to obtain more gears. i think one of their primary concerns is compatibility with existing bikes and the device would be too wide if they added more gears
Any informations about final weight?
or cost, for that matter.
Look forward to getting more info. Keep us posted...although I am sure if they are doing a press camp there will be no shortage of 1st person press releases.
It's honestly not too bad, and ranks with other highend prices. Especailly considering it'll replace your f-der as well.
i really want one for my SS 29'er karate monkey...make it a 2-speed and open up some climbing options without having to build a new rear wheel.
i was originally excited about making my V10 a 2-speed with das haahmahshchmiddt, but ska todd raised a good point about the "granny gear" affect on pedaling.
VPP suspension pedals fine in granny gear, I think Todd's comments were more directed at single pivots, specifically high single pivots. Like pedalling a Bullit in the granny ring you'd get pedal kickback on every stroke, causing that "inchworm" feel.
if you're granny gear is 12x36 yeah...
FYI, the official site has way more info than it used to have...some pdfs on install...little videos, etc. No price or weight that I saw...

so, the bike needs to have ISCG mounts?
it probably won't work with a BB pinch-type ISCG mount adapter, will it?
yes and they need to be prepped (faced) before installing the HS.
no it won't
I wonder how much this thing will weigh and how much it will cost...
Maybe a 2 speed dh bike? Would there be any advantage about running like a 3 or 4 speed cassete in the back and a hammer schmidt in the front?
But then I couldn't get into the big gear and haul on the downhill bike... hmmmm, maybe my dj bike...

some good pix & info. priced at ~$750-800.
