I’m a long time fan of Wilier bikes as they just fit me. I currently have a Cento SR with EPS Super Record. Great bike. I’m looking at the Cento 10 air and the Cento NDR. I’ve been riding for nearly 35 years and still feel like I’m fit and fast (or can be shortly with a good training block -

However, I just turned 50 and have to admit that some days the body doesn’t respond like it use to. Longer rides can be harder. I’m not as flexible as I once was. All of that points to the NDR as it has a more upright geometry. Also it has some rear suspension (sorry) and is compatible with both rim and disc brakes (I’m currently not a fan of discs but this would be a way to hedge my bet).
I have several bikes (Aeroad, ReactoEvo, Specialized Allez DSW,, Wilier Cento SR) so this will not be my only bike.
Question: Which frameset would you buy and why?
