>>1683965Having -higher- handlebars, to a point, is generally more comfortable. Especially if they're below saddle height currently, moving them at or slightly above saddle height is comfy. A lot of swept bars have decent rise to achieve that.
Ergonomically swept bars are similiar to drop bars or bullhorns, and are more natural for your wrists than straight bars. I find that more comfy.
Having a lot of back-sweep can be very bad. Bike sizes go up in 2cm increments. The difference between extra small and extra large is only like 8cm. Common stem sizes go from between 8cm and 13cm, so a 5cm difference, max. Swept bars might have like 20cm back sweep. So alone they can be more difference than going from an extra large bike with an extra large stem to an extra small bike with an extra small stem.
A comfortable position on a bike, is with your shoulders rolled forwards and an arch in your back. That will allow you to dissipate bumps rather than being jolted by them.
Swept back bars will often leave you very very cramped, and naturally not in that position. If they're also high, it can be comfy for cruising around on the flat, but if you try to routinely ride distances and up hills and stuff you can fuck up your back.
After experimenting with quite a few of them i would say try get some that don't sweep back when they bend (like on the left) but that sweep forward a little when they bend (like on the right) and if you want comfy, try and get rise, height, rather than a lot of sweep back. They will almost all give you quite a lot less reach already just because of where the grips go.
