I started with upright North Roads bars. I tried flipping them but did not like them that way but, yes, it was easy to do.
I know I like drop bars on my road bike, so, I thought I'd just "give them a whirl". Pfft!, The size incompatibilities stymied me and I've made no progress.
If the drop bars don't work out, I will consider other upright styles because I find the North Roads bars to be too narrow, too confining.
