If you had to buy a new (non-carbon) handlebar and stem today, would you choose an OS handlebar or a more conventional 26.0mm handlebar? Why?
I'd choose the 26.0 because I like a deep drop traditionally shaped Maes bend. I dislike "ergo" bars with short reach and shallow drops.
The reason I chose 26.0 bars for my recent bikes is because my very favorite bars, TTT Morphe 46 cm, come in 26.0. Long reach, short drop, anatomic bend. Wonderfully comfortable bars. I never see people with deep drop bars ever riding in the drops.
Is 165mm deep? If so, I use the drops on deep-drop bars.

JRA, how many handlebars have you seen break...26mm, no face plate stem?? I have seen zero, in 21 years of wrenching.
i've had a bar come apart in my hands sprinting. it was fatigued at the clamp.
I had an aluminum bar crack but I noticed it before it was a problem. A friend broke aluminum bars two years ago and crashed.
