Progression is a wonderful thing.
Example: In 1995 I was on a Dual Suspension bike with 3.5" travel at both ends and 25" wide "low rise" bars.
Most local people were on hard tails with 22-24" flat bars and "climbing" bar ends on those flat bars.
Many made fun of me, my bike and the "moto bars". ( ok, some still do!)
What do we see today? Even pro racers are using 4" travel bikes and many with 26-27" low riser bars.
( I came from motorcycle racing, so suspension and wide bars were a given for me)
Take a look at the next ride group you are with, I believe you will see more wider bars than ever.
About 6 ot 7 months ago I move from 26" bars to 27" bars: Why? Because that extra inch gave more control on short steep down hills and more control when hitting rocks, logs etc,and slowed down the steering a little***.
With the exception of just two trees on the South Quad trail at Boyette, the 27" bar has not caused any issues.
For Single speed bikes, there is even more reason to go with wide.
Bottom line: Try them wider, use some old grips with ends cut off, move in 1" per ride, find YOUR sweet spot, everyone is different.
PS. The pipe cutter is the hot setup for cutting the bar quickly and cleanly
Measure twice, cut once.
*** May not apply to 29" wheeled bikes, as for what I have seen those things turn slow enough already
