Don't buy the Velo Orange. The front saddle clamp 5mm bolt isn't big enough to have acceptable fatigue life with rider weight on the saddle and stress cycles from road vibrations.

I broke the first one in 3415 miles shrinking from 185 to 154 pounds and finished that ride standing.

I replaced it with a higher grade bolt which broke in 1690 miles dropping to 140 pounds over that distance and had my wife pick me up.

I was using a saddle with carbon rails although that was not prohibited.
