cannondale synapse headset/topcap question.....

[miker2010]

i recently purchased a 2012 synapse carbon w/ultegra in team replica color... pics to follow shortly

however, i want to do away with the hideous 25mm carbon top cap that sits on top of the headset

i want to replace it with something lower, i would appreciate any thoughts on my options.....

first, can i run it without a top cap at all on the synapse carbon? just run the stem right on top of the bearing/bearing cover?

second, could i run one of these 8mm metallic poutine spacers?

on the webiste, it says they are compatible with synapse, but it doesnt say if its carbon or alloy or what year.... according to the website, as long as the headset it a tange system integrated headset, then the spacer will fit.... the specs of my bike list the headset as "synapse Si headset" does anyone who if it is made by tange? is the top bearing an bearing cover thwe same as on the caad 10?

any thoughts on this one?

third, i could run one of those carbon fiber spacers that i can get on ebay......

any thoughts?

thanks
