All those factors contributed to my wanting to build an on and off road touring bike where dirt drops would make the most sense for a mountain bike with drop bars. Pursuant to this goal I found a lot of information on a variety of dirt drop bars. My main objective was to find a handlebar to provide comfort and multiple hand positions during the long haul, something preferable when building a touring bike.
After locating some 3 x 9 Sunrace bar end shifters and reasonably priced Tektro brake levers I decided on the Origin8-Pro Pulsion Alloy Gary-2 Handlebar, 530 x 25.4mm, Black as I had some stems stashed in the shop that would make a good fit for a comfortable yet performance oriented riding position. Photo below of the completed build shows handlebars slightly higher or parallel with bike seat while aligning top of stem and bar with front axle while riding on the brake hoods. I have had the opportunity to run some errands and take it out for some longer jaunts and it felt very comfortable after getting the seat height dialed in. It helped to wrap some Cinelli gel pads under the handlebar tape at the drops for some added cushe. I like the Sunrace bar end shifters and although they are sold individually rather than in pairs the price for a set of 3 x 9 shifters is excellent. When combined with the Ergonomically designed Tektro RL340 brake levers I am enjoying the handling of this particular bike as all this work proved to resolve many of the frame's design issues which were causing a good deal of discomfort.
