The bar ends looked short to me in photos. When I tried them in person at the shop, they felt good in my average sized male paws. Plenty for me to grab onto, and the bar end was actually my primary riding position. I have them on the shelf (sold the bike w/o 'em); here's the measurements:

grip end-to-end: 5.5"
bar end (aluminum portion): 3.0"
effective bar end: 4.0"

The "effective" measurement includes the portion of the grip extending beyond the bar end; since this is where you will place the heel of your hand while riding on the bar ends, I think it's important. But, yeah, they're still shorter than the GR3, GS3, etc..., but I wasn't considering those for paved roads.
