Friend just had his Soma Saga frame and fork show at the local LBS. Really looks much better in person than on the web. Sorry didn't get any pictures. Will after the build is complete though. Nice frame and fork for the money at first glance.

I've ridden a few recumbs and to be honest, even though I know the COG is lower (as is your butt), there's also the leg weight being much higher than usual. I think we have a lot of weight in our legs, and when I'm high speed cornering I sometimes dig/push my pedals (like I do my pegs on a moto) for shifting my COG into a turn. Sort of sliding out my down pedal and pushing (side of bike outside of the corner/turn).

If that were the case (recumbs being better handling in turns), race bikes (motorcycles) would be recumbents like Dan Gurney's Alligator so that they could corner faster, am I right?

I think the head/torso/upperbody weight that is static and higher off the pavement would determine/effect the location of the CoG more so than the legs. Racing bicycle and moto alike, you croutch down towards the handlebar to lower the CoG during cornering.

Unless moto company spend as much R&D into recumbent moto to be come competivie, it's not likely that people are going to find out the real deal.. unless someone like Rossi spend as much time on one of these vs his GP bike:

lower COG on 2 wheels makes it HARDER to turn.

But like a sailboat with a keel, the longer, or further away the top weight is from the pivot point maybe the better. It's a strange sensation but on some of my motos with tob boxes loaded I can actually feel the counterweight when I'm in the twisties. Like a flywheel with momentum it seems to make the bike toss into a lean or at least stay in the lean easier. I agree the COG is static and more effective in the upper torso weight on most riders. I think I'm talking more about "flickability"

The pictured bathtub you posted is great, but with that wheelbase (alone) it's not anywhere near as flickable as a typical sportbike.

interesting topic though.

Hey Bimble...

Heading to Denver this weekend to begin the planning process on a fall journey to ride in the Pyrenees. The last time this cabal of cyclists got together resulted in a 5 day ride around Corsica. :clap

Uh....you also have to climb and accelerate during races. This argument is RIDICULOUS to anyone who has ridden both. Recumbents are for geezers with bad backs....period.

If you're on a flat track and going for the distance, a recumbent can't be beat esp. with the full fairing. But that's one bike/one rider going for distance.

Other than that, you're correct - would be feasible in the typical race. Can you imagine Lance Armstrong on one?

I need a full lane around here when trying to climb on one of those things (think granny gear). Talk about sketchy....

No, you are ridiculous, fact is: majority of bicycle riders do not race, more than likely never will race. And recumbents are for those who allow themselves to enjoy riding a bicycle without suffering unnecessary strain on their bodies.

Looks to me like a personal problem if you can't climb smoothly.. being smooth takes practice, on any bike.

:nod I saw one going up a rather steep grade get passed by a John Deere mower. :evil

Like he said, old men. You're a little defensive aren't you? Hitting too close to home?
