Zero is an amazing frame - fitting & comfort-wise
But like you said, for us OCP Nutz...there isn't much to feed on!
I really love the bottom rimless, but they say the Jawbone is big enough for that not to matter.
You know there is no law that forces you as a rider to adopt the Jawbone.
Ok, I guess there are unwritten rules in the riders' world, but still...
What I'm saying is: worse comes to worse you wait & focus on your Radar, and then perhaps you'll switch when the NEXT sports specific model comes out.
''But the Radar came out like 15 years after the M-Frame''
Yeah that's not gonna happen anymore ;)
