I have two bikes. I'm doing Cool Breeze Century which has about 4500 feet of climbing. I currently weigh 226. I've been training.



All of these rides have been on the Domane which weighs 16 lbs with pedals a d bottle cages. It has Dura-Ace 11 spd 11-28 cassette.

My Madone weighs 19 lbs with pedals and bottle cages and has mix of 105 components with Ultegra crank 10 spd 12-30 cassette.

I took Domane last year but had done little to no riding after getting back from AIDS Lifecycle in June due to three trips to Washington state. Last years pre century looked like this



Obviously very little riding and I suffered on the Domane.

For those bike tech savvy folks which bike would be better to take? Does the weight of Domane make it better choice than heavier Madone with the extra two teeth on my granny gear?
