I am looking for a new set up for my road bike handlebar wise. I am very tempted to switch over to a flat bar. I am running a flat bar on my SS cross bike and have done up to 7 hour rides on it with no real hand fatigue or discomfort at all yet my geared cross bike (also my road and long distance bike) I can do the same exact ride in the same amount of time and my the end my hands are tired and I tend to have issues with hand numbness as well. When on my drop bar bike I always find myself riding on the flats, I think it might have something to do with the angle of my hand while in the drops feels.
I also like the idea that it would be much easier to run an 11-34 cassette on the rear as well which would be nice for a couple tours I have planned later in the year.
If anyone has tried this and could let me know what worked and didn't that would be great.
