They are BIG! If you like thin grips or have small hands then avoid! They are beautifully made grips, they matched my saddle beautifully but after 2 rides my hands ached so they had to go. If you're a big fella or want them for a pootle bike then you'll be fine.
Go with some of the 'brown' lock-ons or maybe do the old Tim Gould (or was it ... Baker?) thing and build up a few layers of bar tape - Charge faux leather is good stuff!).
