Bobbing during high rpm's
I've been riding fixed a while now in an urban environment, but entering the realm of track cycling. I currently ride a 53cm Panasonic track and I am 5'9 running 77.8" (49/17).
When I'm holding a very fast cadence (nearly spinning out), I find myself bobbing a lot. Is there anything I can do to adjust my form, or possibly an adjustment to my bike that will alleviate this problem? I feel like the bobbing is really killing the smoothness of my cadence.
Thanks again for any suggestions.
