mountain bike handlebar width

teleguy57 · #1 08-19-2018, 05:01 PM

Got out my mid-2000s Fisher X-Caliber this weekend, and after riding my Pugsley with wider bars I was surprised at how narrow these felt the ones on the x-cal felt.

I know tmtb geometries have changed a fair amount. What bar width are folks riding these days for general all-around use, and are there implications for stem length or other positioning/fit?

Yes, I know I can experiment but I'm looking for a starting point. Thanks!

740 to780mm I would guess is the normal range for handlebar width. Stem range from 80 to 30mm. clearly, the top tubes are longer and the head tube angles are slacker.

I just installed some carbon Ritchey Bullmose bars. 720 wide. Hate the width. Need to trim 20-30 off each end.

If you don't have crazy descents and climbs and have average shoulder width and strength, I'd start with 760mm and cut as needed. Easy to cut, hard to add length.

My bars are about 715mm. Also run a slightly longer (100mm) stem due to the fact that my current MTB is a hand me down frame from my son & probably on the bottom end of the size I should be riding.
Compared to the 90's/early 2000's things have changed a lot. When I see pictures of me racing back in the day I can't believe I ever ran bars that narrow.
The only disadvantage to using really wide bars is if you have to go between narrow trees. There are a handful of places on my local trails where I have to sort of "swim" through. Get some long bars, cut A LITTLE at a time until it feels right.

I'm running 750mm and 760mm on my two mtn bikes. I was coming from "narrow" bars of the 90s and 2000 eras and things felt really really wide at first. I wanted to cut them down, but others were encouraging me to stick with it. Now I love them. The funny thing though is that I prefer 40cm drops on my road bike.

I'm on 660s. They're comfortable for me riding mostly XC sort of stuff here in Florida where the trees are kinda close. These are really about as narrow as you can get to work with modernish geo.

820s on my ss mtb give me some extra oomph to muscle up climbs

750 on fatbike and 760 on 29er

Ditto. 780mm bars/60mm stem on XC bike, 40cm bars/110mm stem on road.

Both my bikes are 'older school geo' in my Superfly and Top Fuel so I have bars that are only slightly wider than my shoulders.

I'm convinced that geos are going to come back to cloesr to 'normal' once this new trend runs its course

It’s common for locals to ride 800mm bars. I use 740 and it’s my sweet spot. I’ve tagged a few trees, but nothing catastrophic. I use 80mm stems and that is co sidered long by modern standards. A 60mm is what the manufacturer recommended to me, but i felt like the long length was better for me...

As for a trend, it is one (like anything) that really helps when hitting technical trails. Riding on a groomed Jeep trail doesn’t warrant these widths. I think a 680 would be good if you were cruising.

Lots of good stuff here -- particularly appreciate your rationale for your choice. Keep it coming

@JAGI410, I hadn't mentioned it, but my x-cal is a 29er so thanks for your observation about that aspect of frame design.

I'm running 51cm bars (that's not a typo), not including bar end width. The bars are paired with an 11cm, 84 degree stem. I like a road bike-like feel to my mountain bike hand position. I never understood the wide-bar trend.
