Road bike dancing- please help
Dear cyc-friends,
Since I purchased a new frame, my bike is dancing.
I feel like my frame is going left and right and so it looks when i look at my front wheel. Its just not going straight, but a bit left and right.
When i get off my saddle i have to be careful not to fall, for it looks like i'm loosing weight on the back wheel.
Now, i've been asking, fitting... and noone seems to know what i'm dealing with.
I had a fram one size smaller and it was a disaster. It was even worse. (By mistake i was sent one size smaller and i tried to make it work... i almost crashed the frame into pieces one day)
Than i got one no# bigger frame. According to the tabe suggested by the frame company - the size was supposed to be ok now.
Since riding became horror for me this year(and it was my ultimate joy and love) .... i was hoping there was someone who could help me out.
Thank you in advance!!!

Where is the geometry of the frame documented? Is it a racing frame that you're just not used to? A frame designed for criterium racing, IIRC, can be very twitchy, so it takes an unusual level of skill to keep it going straight.

Have you checked with the seller? Have you checked with an LBS?
What size do you have?
Is the headset new? Are you sure it was installed correctly? Are the wheels, especially front, true? Tires installed and inflated correctly?

LBS = local bike shop
I know a bad headset can cause a major shimmy, and I imagine out of true (not straight) wheels or badly adjusted hubs can result in the symptom you describe, but if those don't apply to your bike, I think you need an experienced mechanic to ride the bike and make the problem occur.

getting there... happy as radio. the stem was tooo long.. and.. ah.. i wanted 40 handlebar... and was sure that was what they ( LBS) got me, but,no, it's 44!!! whit a stem too long and a bit ti high seat.. it was a perfect combination to fall off...
but dancing inbetween legs is def. a frame too small. But now, mine shall be ok. So my last local chance said.
