JONES BIKES H-Bar Loop 710 Carbon – By  c_g

Since our initial impressions of the very unusual JONES H-Bar in the fancy and extremely lightweight carbon version, a whole month has passed. That month has seen all the use on the PIVOT LES. Accordingly, I can say that the H JONES bar got more than just a fair chance with me to get used to it before I passed judgement.

The various hand positions this bar provides, while initially unfamiliar, have become more and more normal in the course of time and in the final testing phase is something I seldom think about during a ride, although I do use the full range of options depending on the terrain.


At first I was skeptical about how the brake lever has only one position and was therefore not accessible from any hand placement along the grip. Interestingly, this has hardly had a negative impact. For simple trail sections in between more demanding areas, it is sufficient to keep one finger on the lever. Only in the rearmost position of all will not get you more purchase on the brake lever, but more on that later. The whole hand position of the front loop on the H-bars was deemed to be not for trail use under normal circumstances – but I can well imagine that it makes sense for long road stages or over vast, smooth dirt stretches with headwind. For my local forest trails, the most forward hand position was too extreme and that should not be a surprise to anyone.

Overall, the JONES H-Bar makes a lot of sense because of the diverse grip positions which can be used on long trips, relieving the body from one hand position, .


The very extreme bend of a 45 ° sweepback has not bothered me after I got used to it, even when I added the bar to the last test phase on my Rocky Mountain Instinct trail bike. I also have to say, as a counterpoint, that I never found it better than the 20 ° bend of the ANSWER 20/20 or 12 ° angled SYNTACE  bars that I’ve previously used, but at least it has never really bothered me or affected the handling.

What did bother me was the limited steering lock to lock range. Depending on the crank position, the legs and the handlebar can argue over the same space in technical sections, especially in uphill switchbacks and when turning sharply. I was often forced to dismount. More than once I’ve been thinking to shorten the 710 mm width to something less by trimming 3-4 cm off the handlebar, where I would only lose the the grip position that I have used least of all.

Even before I got the bar for the test, I had a long conversation with Jeff Jones in which I gave him my exact body measurements and the geometry of the bike they would be mounted on. He said that I should try, instead of the current 80mm stem in use something more along the lines of a 50 mm tiller.


However, even after long rides with that 50mm stem, I never got comfortable with it. That’s why I went back to the previous stem.

At another point, Jeff Jones may well be right and that is regarding the handlebar height in relation to the saddle height. On the PIVOT Less it was about equal, but the with move to the Rocky Mountain I wanted to try something and I installed the H-Bar with a -15 mm Rise. The consequence was that I was constantly riding with a lot of weight on the wrists which nearly eliminated the multiple hand position benefits. No matter how many times I changed the hand position, I experienced numb fingers. It was only when I turned the handlebars back to level with the saddle did the various grip positions came back into use and the long-range character of the H-Bar was restored.


Test Conclusion: In summary, the JONES H-Bar Loop 710 Carbon has upsides as well as downsides. When it comes to long rides, mostly on less technical trails where one is more likely to emphasize the touring experience, then the H-Bar, if you have it set correctly, is a prime example of ergonomics and comfort , As already said about the Lauf Trail Racer fork – if I would ever attempt the Tour Divide, the JONES H-Bar would be my first choice for that event. Through the various options of build material Jones offers, one can easily choose the right model for his needs and budget.


The Jones H Bar Carbon, on my typically technical/rough forest trails, was seldom bad but the fact remains that I have never found it better than other bars either, and together with the restricted steering issues, was not a convincer for me.  Jeff’s prediction that I would buy the H-Bar handlebar after the test will not play out to be true.

In short – at present I see the JONES H-Bar therefore as a prime alternative for long tours and moderate trail conditions, but would not necessarily recommend it for the aggressive all-mountain or even enduro rider with most technical trails.
