I’ve got a 750mm "wingspan" and it rocks. Originally bought the bars with intent to cut down (factory marked) but liked them wide after the first test ride. I’ve got no problem clearing tight singletrack…wider bar=more control. Now, at some point, the law of diminishing returns takes its rightful place but the inverse is also true if you’re considering going narrow(er). Everybody is built different but for me 750mm is the sweetspot. My only problem is cruising at speed through the gate opening between the parking lot and trailhead where I ride…it is literally 752mms. 😃
