That hub is wild. Bearings on only side is nuts? I would have loved to see that. Any more pic on it?

So, tell me how that this is wild? Cars have been doing this for a century. I've never seen a car that has a front wheel set up in double shear.

I was at Interbike. It was my 29th year of our trade show (it was called something else back in the '80's)

Just unusual to see a hole on one side of a hub. less resistant I suppose

The trade show were in LA back then, not Vegas. I've been to a couple of them but never in Vegas

I need some brakes for some of my newer BMX bikes, can you hook me up

Here is the BMX version..



One day maybe I'll get around to building mine uo..

What's the advantage of doing it that way beside weight and rolling resistance?

It looks *****en!

Non really, they stopped making the BMX version after a few years as they broke, but that was late 80s, early 90s. The Cannondale Lefty been around a bit now, so they at least have it figured out (their propaganda below)



Innovation - LEFTY

SUPERIOR PERFORMANCE THROUGH UNCONVENTIONAL DESIGN.

The LIGHTER-STIFFER-STRONGER-SMOOTHER front suspension -
Now with SEALED HYBRID NEEDLE BEARING TECHNOLOGY


LIGHTER
Lefty's minimalist single-leg design lets it be lighter than most competitors’ lightest XC race forks.

STRONGER
Lefty's dual crowns and oversize inverted structure give it such strength that even the lightest Lefty can out-perform burly all-mountain forks in destructive testing.

STIFFER
Lefty’s stout structure, combined with its "square-in-a square"stanchion design and lower glide bearing make it torsionally stiffer than any fork in the world, for pinpoint steering precision.

SMOOTHER
The heart of the Lefty, Cannondale’s patented hybrid needle-bearing technology keeps the suspension moving freely, regardless of load. Even under the hardest braking, impact, and steering forces, the wheel is able to track the ground fluidly for maximum control.

WORRY-FREE
The new hybrid design allows the entire fork structure to be completely sealed against the elements for long service life and features auto-resetting needle bearings to eliminate the need for regular manual resets.

KEY LEFTY TECHNOLOGY




DUAL CROWN INVERTED DESIGN
With the larger, stiffer fork tube on top where it can more effectively fight flex and add strength, and dual crowns connecting it solidly to the headtube, the Lefty's unconventional design is simply the lightest, stiffest, strongest way to build a fork.



SQUARE-IN-SQUARE DESIGN
The needle bearing races form a square-in-square interface between the inner and outer fork legs, preventing the two tubes from rotating relative to each other like the round-in-round design of traditional forks. Contributes to Lefty’s incredibly stiff and precise handling.




HYBRID NEEDLE BEARING SYSTEM
Friction-free needle bearings provide unmatchably smooth suspension under all loads, while the lower glide bearing provides additional support for improved stiffness and steering precision as the fork moves through its travel.



DURATHON SEALING SYSTEM
A comprehensive internal and external sealing system keeps the good stuff in and the bad stuff out, allowing for more than double the time between recommended services than our competition.

Your strength to weight or at least your rigidity to weight ratio will drop with a single leg design. Making the single leg bigger in diameter would help overcome this but I don't like the look of it anyway. Not something I would want to ride downhill.

I know the Left's been around for a bit, but not sure its selling or popular with riders. I do not Mtb so have no info there. When I first saw it, I thought, what a joke just to save weight, but looked cool with one leg to the fork. How rigid can one leg was the first thing I asked back then. Cannondale must know what they are doing.

Very COOL.

[jyl]

Yes, very cool. Wonder what that is like to ride? Seems like an odd combination of crank forward and low-ish handlebar.

C'dale sure ain't afraid to try new things. Remember this?

You still see Leftys in the cross country and 24 hour race circuit. They work just fine and hold up to some hardassed racing (some of the 24 hour guys are REALLY fast).

I rode one and didn't like it. It worked very nicely, but I kept staring at the front wheel. I run into enough things when I'm watching the trail, so this was a deal breaker for me and I wound up with traditional two-legged forks.

How can you tell if an e-bike complies with max power limits if the motors look the same at different power levels? So far this hasn't been a problem in my experience, I seldom see any e-bikes on the road. But it will be.

I'm seeing a whole lot more of electrics. Not sure if municipalities regulate e-bikes and I have no problem if they use a bike path or trail. Surely they are improving and lighter weight.

A look into the future with the tiny Gruber bevel drive electric motor set into a seat tube / bottom bracket. Priced at a whopping $2,400.. just for the parts and has to be custom installed. Cylinder type battery NiCad packs like the ones used in a Paslode nailer make the whole package even more stealth.
Remember the rumor Fabian Cancellara was using a secret motor to assist him on both his victories at the Tour of Flanders and Paris-Roubaix?
