Cane Creek bar ends, Thorn "bar middles" give a nice "time-trial" position.
Merlin Ti handlebar, Grab-On grips.
There's no star nut in the steerer, and no spacers. Clamp-on collar holds the headset together, allowing me to raise or lower the handlebars without messing with the headset adjustment. Don't try this on a fork with a plastic (carbon) steerer!
The absence of the star nut also permits this unusual computer mounting solution. There's no special hardware involved, I just squeezed the clamp mount of the computer together and pushed it into the steerer. In a later modification, I ran the wire up through the middle of the steerer for an even neater appearance.
