My current bike is 10 years old with 680mm bars and when I was demoing bikes all this summer, it was really strange to jump onto 780mm bars and that not be the defining characteristic!
However, I did 3 demos in a row last month without riding my bike in between. Then jumping on mine was really odd!
How long is your stem?
If it’s 50 or 60mm then if, after a while you still think it’s too long, you can always drop to a 35mm.
As long as the seat mast isn’t too high for a 5″ dropper, they you’ll probably be fine.
Just to compare. If your tt is 610mm, that’s 10mm shorter than the Bird Aeris Medium, but also 25mm longer than the SC Solo Medium – lots of variance!
