Loved them. I ran them just below level. I never measured the angle. I'd fancied a pair of Jones bars & when a fork, bars & stem came up as a deal I went for it. I'm running those at the recommended 15 degrees (They recommend 15-20).
The Space Bugels may end up on my ebike P7 which is going yet another makeover. As it's a commuter I have flat narrow bars on to get through the anti-motorbike gates without stoping but I think comfort will trump practicality.
I ran the Space Bugels on a 120mm 5 degree stem. I built the bike that way so there no change of stem. The Orange Fido stem in an earlier picture on this thread didn't make it to the build. The stem is a 25.4mm clamp so I couldn't use it on the 31.8mm Jones. The stem that came with the bars is 110mm 0 degree & so far so good. I've done about 150 comfortable miles on it over the last few months. The whole geometry of the bike is different though as the a-c of the forks is a good bit more that what was on before but it climbs well although I've still to try it on proper steep stuff. At least with the Loop bars it's easy to get your weight forward. I dabbled with a flared bar gravel bike in the same period & found the Jones way more comfortable.
