In the stores, many of the bikes I recently looked at came with about three almost four CM of spacers under the stem. I don't remember what the TCR had as they didn't have any near my size and didn't get any before I found a bike that rode well and had what I wanted.

What I was trying to convey was just because the bike will allow you to get very agressive in position, it may not be any more aggressive than the other if they ship them with more steerer tube above the headset than another brand.

So if you can try out both bikes. I wouldn't eliminate one based the spec'd geometry when the bars and stem aren't at that position when they build the bike in the shop.
