Hey djb, it's a
Jones H-Bar. The design has changed a bit since they were originally released, and he now offers the Loop H-Bar and the Cut H-Bar. That is the Cut H-Bar pictured above. A recent back injury made it too uncomfortable to ride in my drops, so I was looking for an upright alternative that provided multiple hand positions. There aren't many bars that fit these criteria. Trekking bars would be one option, but they seemed a bit more bar than I wanted. So, I gave the Jones bars a try. They are not cheap at $120, but I was willing to try them in order to get some pain relief. Well, it worked. The bike is much more comfortable to ride now, and I really like how they handle the bike too. Makes my Cross Check seem like a cyclocross/classic mountain bike/29er mutant, but in a good way. I've taken to calling my Cross Check "the bat bike" because the bars remind me of the Batman logo.
I actually wrote a review of them here.
