[QUOTE=lasauge;20784524]I tried mustache bars a couple of times on different bikes and could never get comfortable with them as they were too wide for my shoulders, and led to hand and wrist pain when used offroad. Unlike Tom [MENTION=152773]noglider[/MENTION], I did find the 'over the ends of the brake levers' comfortable as I stretched out in a position sort of like aerobars, just wider, but I couldn't spend time enough there to justify putting up with the other drawbacks. Note that I think the secret to making such a position tenable is that you have the have the levers point straight ahead so that there's enough area available to grip... lever shape matters too.
Do you mind explaining how brake lever shape matters in your experience? I'm in the process of buying some levers to go with the mustache bars and would appreciate your input. Thanks!
