When I bought my Distance, I was told by a great bike fitter, and an Ellsworth dealer, that I should have the 19" size. I am just over 5'10.5", with long arms and legs. The fit feels good and I love the bike! When I ride fast fire roads, or steep downhill, I feel very confident on the bike. But on tight singletrack I feel I am having to "manhandle" the bike and it seems big to me. Should I be satisfied with a bike that I feel confident on and fits good, or regret that in curtain situations it is hard to maneuver and trade it in on a 17"? Would the 17" take away some of the "confidence" I now feel with the larger size?
