Comparing the Madone 3.1 WSD and the Lexa SLX, the main differences are:
- frame material (carbon vs aluminum)
- Madone comes with a compact double chain ring, Lexa comesw with a triple
- Lexa frame comes in a 43, if you need that size
The specific gearing is:
Madone: SRAM Apex, 50/34 (compact) vs Lexa: Shimano R-553, 50/39/30 (triple)
Both have the same cassette: Shimano 105 11-28, 10 speed
So I think the Lexa would give you some lower gears for climbing. However it's possible that the lowest gear on the Madone would be sufficient; I'm okay with lowest gear on my bike, which has a compact double, and I ride up a fair number of steep hills (with asthma).
The wheels are also different, though I don't know much about wheels so I can't say if those on the Madone are a significant improvement or not.
Madone: Alloy hubs, Bontrager Approved alloy rims
Lexa: Bontrager SSR (43cm: 650c)
So I would say the Lexa SLX looks like a very good road bike for your purposes, but if you think could afford the Madone, I would give that a test ride also to see how the carbon frame feels. Also test ride on a hill to compare the gears, if you can.
