Anyone know a messenger who rides a sky blue brakeless cyclops track bike? Just saw the dude go across traffic at front and bay, looked like he had a "the messengers" jersey on or something.

Also, I have been noticing that when I ride with no hands occasionally the front end of the bike will start shaking and flexing back and forth and the handlebars will start twitching. It gets worse the faster I go and I have to grab the handlebars when they start to really flail around. Is this a problem with the bike or a fact of life? i don't seem to remember this happening before, its more of a new occurence. When I lean forward with no hands it seems to help the problem somewhat. Front end seems nice and solid and I did a full maintenence of it a week or two ago.
