All Jones H-Bars use a 31.8mm stem clamp diameter, 22.2mm clamp size for controls (standard mountain bike style). The entire front loop has a 22.2mm diameter.
The Cut H-Bar has the same hand, stem and brake lever position as the Loop H-Bar but with the front cross bar cut out. The cross bar sweeps forward to allow the levers to go behind the cross bar instead of in front. This gives longer uninterrupted hand positions and will allow trigger and grip/twist shifters to fit on the rearward extensions (unlike the original H-Bar and the Cut H-Bar). The continuous front loop of the bar enhances stiffness and is good for additional aero hand positions and mounting lights, GPS devices etc. This bar provides comfort and power with an impressive weight. With the levers in the optimum position the rider is superbly placed for fast riding while still enjoying all the hand positions available. The rearward extensions allow extra leverage and a wider hand position - be it for comfort or power. All H-bars are for a 31.8 stem and the cross tube is now tapered and butted with a 31.8 mm clamp area. The grip tubes on the aluminum version are also butted for strength, and weight savings.

This H-Bar is excellent--lightweight, sturdy, and functional. As far as that goes, I couldn't be happier. It's a great addition to my Pugsley.
-1 star for how difficult Jones bars are to find, though--it was either here or my price-gouging LBS, unfortunately. More availability would be appreciated.

I'd been having a lot of trouble feeling good on a bike I bought two years ago and had been riding on a near-daily basis throughout the spring/summer/fall seasons. Recently, I bought the H-Bar - and it changed everything. This bike now makes sense and is a complete joy to ride, and it's all thanks to the H-Bar.
I've got mountain brakes and friction shifters mounted near the handlebar "join" points, and all of my accessories (lights, bell, etc.) mounted on the front "hooks". This gives my hands plenty of positions. The variance in bar width makes riding a pleasure for any occasion.
The handlebars took a week or so to get used to. I was coming from a drop bar setup, so I wasn't prepared for the effortless control that these wide bars had to offer. Now they feel completely natural and I don't see myself switching to anything else. On the contrary, I'll be buying another set for my fat bike!
