Now I'm thinking I might convert my CX bike to the same flat-bar + bar-end setup...sort of like a "lightweight" 29er, or an "aggro" hybrid! I've got a spare flat handlebar, but I'd need to get the bar ends, grips, v-brake levers, and some 8spd shifters (Gripshift, preferably!). Hmm...I wonder if I'd need a different stem as well? At the least, maybe I'll try out a set of in-line levers on the tops of the drop bars, although it seems to me that strong braking from the tops of drop bars might feel too "narrow" to be stable during the sketchy stuff.
At any rate, food for thought, and another bike-project to add to the (ever-growing) list!
