I'm assuming you still have the regular (7/8") bar size. This size handlebar is only available with a crossbar. I recommend getting either Renthal 7/8" or ProTaper SE aluminum bars in your favorite bend. These suckers can handle abuse and have thicker walls (aluminum needs it to compete with steel) and shouldn't bend unless you have a bad crash, in which case the bars will be the least of your worries.
You can upgrade your bar clamps (or whole triple clamp assembly) to accept oversize (1 1/8") handlebars. I have these on my bike. I recently got a new set of Pro Taper Taperwall handlebars and have already crash tested them many times, including one mild concussion (3rd gear into a big tree!) and can honestly say they are the best handlebars I've ever had. They are so strong that instead of bending, the bolt holding the bar clamp to the triple clamp bent instead. In oversize handlebars you have quite a few choices, with the most common being TAG, Renthal Fatbar, Renthal Twinwall (has a crossbar), ProTaper Contour and ProTaper Taperwall. There are also numerous oversize bars for the budget minded rider (Moose comes to mind). Personally, I say spend the bucks and get ProTaper Taperwall bars. Excellent product.
