why's the bike lean to to the left when no handed?(23 posts)

why's the bike lean to to the left when no handed?ishmael

I'm pretty sure it happends to everyone on every bike. Wheels are in the center, seat is in the center, cranks and pedals are centered. All the weight is centered but when I ride no handed and look down everything is always leaning way to the left.
I have the exact same problem.Qubeley

Must have to do with asymmentry of body(strenght of leg, etc), not only that, when I ride no handed, my left butt is more to the center of the seat, if I try to correct it, I won't even be able to balance the bike. My butt is centered when I use both hands though.
tilt your head to the rightLeroy

Your head is heavy and it's far from the frame. Are you looking left?

Most likely due to the "crown" in the road, which is higher in the middle and slopes downward towards the sides for drainage purposes. That's my guess. Try riding no-hands on the left hand side of the road and see what happens.
maybe you need a front end alignment nmDougSloan

Believe it or not that used to happen to me untill I got custom orthotics for my cycling shoes. (no I didn't get them so my bike would go straight) After I got them my bike went straight when I let go of the bars. I guess it had to do with the position/angle of my foot in relation to the bike.
The cruiser did it for years ...Humma Hah

... I always thought it was the fact that the stays were bent from a badly-landed 3-ft jump in the 70's, when I fancied it a cruiser-class BMXer. But, before having it powdercoated, I had a pro straighten it. He took out about 3/4" of misalignment, and the bike still did the same thing. Then CyclArt powdercoated it, and in the process discovered the headset was badly indexed. They had the original-type NOS headset for it, and installed it for me.

The problem is all but gone, and the bike handles like a dream no-hands, like it did new.
overhaul headset / could also be wheel dish but not sure -nmbenja15

It has happend on every bike I've ever owned. I assumed it was what bikes did. It must be me. Accepting that, and assuming it's not the bike (every bike I've owned has done this) I dont understand how an aligned bike could ride sideways while having almost all one's weight centered on the seat. I do have about a half centimeter longer right leg. that's the only imbalanced part of the man-machine amalgamation that I can think could possibly set me sideways. But that still doesnt explain how and I dont think thats it. I think youre all wrong, I think youre all sidways and you just dont know it.
Well. then how's it hanging?seyboro

You know, you've got to center things properly over the saddle.

Ah no wonder Lance's bike always leans too ;-)

I don't think anybody mentioned it, which is completely weird (or maybe I didn't read their messages carefully), but it is probably because your frame is misalligned. What the hell is front end alighnment anyway? Frames that are crooked have the whole rear triangle (seatstays and chanstays) misalighned. i.e. bent to the left or to the right. I had a bike frame like that and I had to lean left to keep it from riding to the right. Any relatively expensive frame should not have this problem. Non of my high end frames had this problem. What road crown? What headset adjustment? What are you people talking about?

Woof the dog.

So there is more weight over there, and the bike has to lean to compensate for it. You have a tendency to turn when leaning. Just a theory. The weight is low and probably negligible in the long run. Ride faster.
Field testing seems to verify the crown theoryretro

I notice the same thing years ago--even my tires would wear faster on the left side of the tread than the right.
After trying for a couple of days to puzzle it out, I finally came up with the crown-of-the-road theory somebody else suggested. I rode a couple of blocks on the wrong side of the road, and the bike seemed to be leaning to the right.

I've noticed the same thing. I used to go out on roads with crowns and sure enough, the tires wore faster on the left side. Riding on flat bike paths and on top of road crowns, sure enough, wears the tires evenly on both sides. I have documentary evidence.

As far as bikes leaning this way or that, well, if it's obvious, the bike frame is probably out of alignment, the wheels are off track, or the rims, usually the rear, are off center.

I was surprised in days of riding with a single pannier on the right side, the bike didn't seem to lean at all. It rode exactly the same as without the pannier.

In any case, if the bike consistently leans to one side, the tire wear pattern will eventually show it. On the other hand, if the tires wear evenly side to side, then the lean must be imaginary, right?

this is just a lean while no handed. I plan to test some theories tonight. Hopefully I'll be able to see my bike.

Your heart (and most others on this forum) is on the left side. The bike must follow the heart.

Reading from Eddie B's book, Bicycle Racing, from the late 80s, he mentioned that most crashes were on the left side of the body and put forward the theory that it may be due to the heart being on the left side.

I know most of my crashes tend to be on the left side.

Also, when doing high speed turns are you more comfortable turning right or left. Boiled down to a crit, right turns or left turns? Sort of a track or Nascar question.

It could be an interesting study.
