I finished putting the Choco-moose bars on my Hunqapillar and got it out for a short ride. Installed them about halfway between 'max height' and 'slammed down'. What a fun improvement over the Noodle drop bars! I haven't had that much fun on the bike in a while. Really enjoyed the upright feeling, I was able to see so much more than having my head down. Much better for my back and posture too. After 18 miles, I thought that all the extra weight being put on the sit bones might cause some discomfort, but there was none.
In terms of hand positions, I found that I used the normal grip area most of the time, and then would occasionally move the hands forward to the horizontal area near then stem when climbing, to lower my center of gravity a little and put me a little further forward. Otherwise, when climbing, it is so upright that I felt like I was too far back on the bike. The horizontal hand position felt very similar to the top position on my Noodle drop-bars.
I found that I wasn't able to use the 'intermediate' hand position on the bars, where the bars curve. On the right side, my shifter is mounted there, but even on the left side where it is open, I didn't like the feel.
On the road at higher speeds, I noticed no overlap between my knees and the handlebars, but at low speeds, there is some overlap, which could be a problem if you do any off-road slow speed technical riding. Shouldn't be too much a problem for me, but I could see where normal non-curved mountain bars (like the Bosco bar) would be better for that type of riding. It could also be that my frame is on the small side for me. (I'm 5'10", with the 54cm frame).
Overall, very happy with the Choco-moose bars, an excellent upgrade for me. I had been thinking about getting a 'fat bike' for a while, and almost decided to go for something like the Surly Ice Cream Truck, which looks like a ton of fun. But rather than drop the cash on a beast like that, I decided to alter my current ride instead. Still waiting for my new fatter tires to arrive (Thunder Burts), which should the make ride even more fun.
I attached some photos of the bike, one pre-Choco-moose and one post Choco-moose.
