And the prize is...a well-deserved beating? ;)

Maybe it has something to do with some bikes have a lot of front end stiffness so some people can't tell a difference, but others do.
I think that most people on the Cannondale forum are a little jaded by questions such as hers, which is what leads to the inevitable silly responses. The truth is that Lefty forks don't pull to the side. Although they look like they might, they don't. But sometimes the cable routing is awkward, which can pull the wheel to one side or the other--which is not a problem that is unique to Leftys. If the wheel turns when the bike is lifted off the ground, it's probably a brake or derailleur cable that is either too long, too short, or somehow pulling or pushing on the bars.

I reckon that's most likely but one other thing you could check...Is the wheel dished correctly? It's harder to notice if dishing is off on a Lefty.
For what it's worth, mine definitely doesn't pull to one side or the other.
Problem I have with the Lefty is when I forget to use the rear brake and only apply the front. Since the brake caliper is also on the left side the bike just whips a tight left turn that scares the heck out of me.
hey,i actually have a serious reply!
how is the dish on your wheel? i have zero experience with leftys, i usually make light of them when i see them, but if your wheel was not centered under the steerer there would definitely be this kind of problem, i'm guessing that they dish centered between the flanges, and a canondale dealer would have a truing stand spaced for this. Wheels usually go out of dish for me away from the brake ,front and back,and i really use alot of front brake and i guess those spokes see alot of stretching and releasing so the ones on the brakeside, particularly the ones that get unloaded when braking, tend to loosen and the wheels dish goes off a bit.
it's not that hard.....actually....:D
This guy gets paid to do it

Riding no hands isn't normally an issue. Lefty or not.
Most of my time is spent on a Fat Lefty at this point, and I was not expecting to have issues with riding no hands, which I didn't. What did surprise me was I could aim for any pot hole I wanted, plow through, and be none the worse for wear. Road no hands, pounding holes for almost a mile. :thumbsup:

my bike does pull to the right....
Actually I just wrote to Cannondale about the pull problem I have. Next thing I started looking for info on the web and found this forum.
In February I've got myself a new Flash 29er Carbon3 and I love it. I noticed the bike is not well balanced though. If I ride it no-hands I need to lean quite far to the left (bike pulls to the right). I tested another identical bike from my local reseller to discover the very same symptoms.
I checked the routing of all cables and changed several configurations but nothing changed.
If I stand above the bike aligning visually frame and front wheel it appears the wheel is moved toward the shok. Now I am thinking about adjusting the spokes so the wheel is moved away from the lefty by 2-4mm but I will wait for answer from C-dale first.
That's what is called "dish"
The 26 answers in this thread who were suggesting to check the dish just meant that.
Just pull a string from the front wheel to the rear wheel. There should be four points of contact at the same time on the wheels.
Use a straight edge with a good rear wheel, no tire. See if it sights straight with the head tube. Also check against the seat tube. Many bikes have misaligned dropouts or linkages and will cause pulling.
Out of 8 assorted frames I've owned, all needed some tweaking with a round file at the dropouts to get them straight. I mean really straight.
Mine pulled to the right!
I resolved the problem by re-aligning the rear tire and making sure it was nice and tight.
When I leave my bike perfectly vertical on a service stand, Lefty always goes to the left, which is natural due to gravity force, and it does the same when I ride. I have to lean the bike to the right to be able to ride with no hands. I think it might be different in other bikes, depending on the head angle. I owe Cannondale Prophet with 69* head angle, and that's pretty "flat" for a bike with asymmetric fork.
Does anybody know if the body's COG is the same left to right? Maybe that left pull counters that asymmetrical COG?
I have found a straight bike/fork pulls straight. If the front wheel's contact is to the left of the rear, It will pull to the right. If the front wheel is to the right of the rear, it will pull left.
If the rear wheel is toed to the left, it will pull right. If the rear wheel is toed right, it will pull left.
Out of 9 frames I've owned in 12 years, the Sette Riddik has been pin straight with any fork I've used on it. All other frames pulled one way or the other alittle. Lastly, many forks are sprung on one side only.

Mtb bikes and compnents are expensive and due to location many must rely on these forums to form an opinion before making such an investment. Knowing this I wouldn't try to steer someone toward a rediculouse bias based off of nonsense passed off as "Fact"!
So NO this is not true!
I ride my Lefty 20 miles to work and 20 miles back 5 days a week and have never felt this tendency when I let go of the bars. MAybe you have bent seat rails or something?
My personal take on my Lefty Fork:
The fork feels like a short travel XC fork.Besides the feel of the needle bearings it feels just like any other.
It has it's pro's and con's - just like any other. I don't love it and I don't hate it.
It just serves it's purpose. It's light and stiff, responds well to terrain and has shown zero signs of weakness but it requires some servicing to ensure best function and reliability. (as do many others, e.g. Fox forks)
I personally I have jumped, climbed, twisted and turned my lefty DLR for 3 years now and it's done fine, but I have also had it serviced by Cannondale every year without fail as my LBS has suggested at a cost of around $200 per service. (Which I do consider to be a high price but in my situation I will save that in gas money in a week!)
- I find the fork to be very reliable, consistent and trustworthy.
- It doesn't flex or twist so I know that the fork will always be pushing my wheel back toward the Earth in the interest of solid traction.
- $200. is expensive for annual service.
- Must be sent to Cannondale for servicing ( Two weeks is the longest it has taken for my fork to come back)
-Limits aftermarket Hub and stem selection.
-Hope this helps.
The Flash 29 with the lefty PBR is definitely more difficult to ride with no hands compare to the my other bike Niner one.
my lefty was pulling to one side as the front hub bearings had worn out and there was play. replaced and now its back to normal :thumbsup:
I may be late to this party but I can contribute. I am a new Lefty owner and I was concerned with this issue. So, testing the fork for no hands riding was on my priority list. I have the new 2013 Lefty and I report that you can ride no hands until the cows come home. I'll see about getting video if I have the time.
In addition, it does not pull.
Better late than never. The thought of this never entered my mind when I was buying my Flash 29er...After reading this of course I had to try it.
I can now say yes, mine does tend to track left but only very slightly. Could be the weight of my Incredibell mounted on the left side of the cockpit that could be causing it, or my poor (but improving) balance.
I just transferred my Lefty + wheel to another frame and I am now convinced more than ever , that the 'pull/push' phenomena is cable related.
On my other setup , a 1FG with a Rohloff and hydros , I could ride no hand without any problem and on my new setup , the 4 cables passes on the same side of the frame and it "pushes" to the right. I can compensate but I definitly feel it more than I use to.
It's the exact same fork and wheel , with two different cable running setups.
