What are opinions on what makes a good century bike? Is it marketing hype or do the endurance geometry frames seriously benefit longer rides vs. just whatever the lightest and most aero bike you can afford will do for cutting your time? I'm speaking in terms of consideration of climbing hills, etc. as well.
I'm looking at a few different carbon bike options that might benefit ride comfort over my aluminum bike possibly and maybe a little lighter to help with climbs.
I personally do seem to occasionally notice a strain on my neck even with my endurance geometry Cannondale Synapse after several hours in the saddle in pursuit of a century. I see the reference of htfu used in the road bike forum and maybe that's something to consider.
