Yeah, that's sort of my point. Yes Lahar(with floater), but I've owned Balfa BB7 x 3(no floater), Brooklyn Race Link(floater), Katipo X 2(with and without floater),BMW SR6(with floater).
I'm not sure where you get loose traction from.
this is a good point. i've never ridden a high pivot w/o floater, but the bike is just ridiculously planted & neutral through the most ridiculous stuff you can throw at it. allows a greater comfort margin for getting sh1t done. brake hard through chunder & braking bumps & it stays planted. pretty neat.
Anything is possible, and I don't know whether there'a been any FEA work done on the frame (I think not)... but the frames I've seen (prod and pre-prod) looked burly enough.When the biker begins to lean on sharp corners and sitting on the saddle, the gear bed will begin to crack... that seat-tube has not so good force dissipation trough his bed.

It's not a motorcross bike. How many times would this scenario occur(rider sitting cornering with bike not being able to deflect)?
Rubbish!
2 years ago a side hit in a tree bent my 6kg cr-mo in this area. In fact I prefer to do light-to-med dh in sitting position nevertheless that I'm not so heavy (~71kg).
Why? Can't understand you but to be precise I'm doing a research for totally random bikes with interesting ideas not from yesterday.
Oh, well in that case you must be right about the fatigue and strength properties of a totally different frame.
Awesome, rep added - mainly for the trollface.Rubbish!
You forgot many factors. I have included them below. YOU DON'T KNOW ANY SCIENCES.

Speaking enough for all ...
the alfine 11 runs about 5-600. Previous versions around 240, I think. Shifter and gear is extra.
a bit portly, though not to far off the mark for a 1st gen design i suppose. guessing you'd be able to hit 40lbs w/ a weenie spec.
First revisions usually are. I expect to see this drop in future generations of the design. The real weight weenies can run a hub with fewer gears.
how much do Lahars weigh?I wonder how much weight they could save by making a carbon mainframe
I think they are pretty light. I just got one and need to build it up to try it out.how much do Lahars weigh?
my frame w/o gearhub & floating brake, but with shock & ti coil spring is ~9lbs even. so yeah, potential for significant weight savings.how much do Lahars weigh?
how much do those Rohloff hubs actually weigh anyway? and that frame used a 9.5x3" shock right?
true but you also lose a relatively insignificant amount of weight compared to a standard drivetrain...you still need a second hub and shifter. You're really only losing a few links of chain, 8 cogs, and the derailleur.Remember that most of that mass is sprung and central in the frame. i.e. where you'd want it to be.

Craigslist special?
A friend had one and I traded him another frame for it. I was always curious about those and remember Cam Cole absolutely shredding on his around here a while back. So, when my buddy was ready to build up a new bike I offered to trade.
A buddy has been on one for years and two seasons ago another friend and I gave it an overhaul. We had to epoxy new bearings into the BB and he machined new integrated headset cups that we also had to epoxy into the frame. The chain tensioner got a whole new spring setup as well a bunch of other bearings and the bike was brought back to life. I have a little history with this one and I know I can get her running smooth again, I hope.
a Rohloff = 1600g
FWIW, I was told 39lb for one that's been built already. No way of confirming this, but seemed about right.
Is it the rare short one?
Maybe, it seems very short.
