What is the men's version of Trek Lexa SLX
Looking around their site, the Madone 2.1 seems to have similar components, yet is only $1,319.99 compared to the Lexa which is $1,649.99.  Looking over the specs,  I can't see why there is such a discrepancy in the price.  The Domane 2.3 is also quite similar and has the IsoSpeed decoupler on the frame and appears to hace rack mounts based on the picture. It is priced at $1,869.99.

There also seems to be a substantial price difference between the Silque and the very similar Emonda S4, which are priced at $2,089.99 and $1,649.99 respectively.  It's interesting that the women's specific models seem to be so much more expensive.  Maybe there's something I'm missing out on with the pricing.
