Works a treat on my Superfly, bar ends in the middle which are roughly equivalent to the reach of the hoods on my gravel bike (a bit shorter actually).
I’m not running a particularly short stem either, 75mm I think, so perhaps I just got lucky with top tube length. I still found it more uncomfortable on longer rides than riding my gravel bike, which I couldn’t really understand, but I think I had the saddle further forward which places more weight on the hands, so I’ll need to experiment with sliding the saddle back again.
edIt: although I should say most of my Superfly’s gravel credentials are thanks to the Vittoria Terreno semi-slicks. Super rapid but a bit floaty over loose corners and braking…
