Help with new fixed gear.
 

Hey. So as of current I've started assembling my newest fixed gear bike, but I am unclear on one issue surrounding a frame I wish to buy.
The frame in question is the Cinelli Vigorelli track frame. The silver posts to which the stem would fit onto seems to be greatly oversized, does the frame come stock like that? And I assume this has to be cut down to my specifications correct?
Any and all help would be appreciated.

Correct, all forks on stock framesets come with extra steerer tube for you to cut it down to your need.

actually, you are required to keep it that stock length and use lots of spacers.

It depends on whether you expect to sell the frame in the future. If so, you don't want to cut the steerer tube, because it will affect resale price. Otherwise, typically what people do is to cut it down gradually in increments, always leaving some spacers above the stem to permit future changes in stem / bar position. I've got all my bikes set up with between 10mm and 15mm of spacers above the stem. However, I never have more than 20mm of spacers below the stem, and if I require more height to the bars, I'll get a stem with more rise and flip it up.

Just don't cut it all the way down because it looks cool as you may regret it. You can always stack risers on top of the step to dial in your position.

Measure twice cut once
