Angle of bars and for the loop, I put two bottle holders in the gap and they don't budge, mostly though it's the hand positions they offer. I can stretch out but still control the bike if I want to.
That's quite a long fad... Jeff has been making and refining his bars for nearly 15 years. :)
He has a couple of good videos on YouTube explaining the development from the original H bar to the loop version.
PS can anybody definitively state why loop bars exist? I’ve asked around. People shuffle their feet and mumble incoherently.
Surely they’re the most pointless fad ever (I’ll be ordering some soon then)?
