At 17g, this is one of the lightest seatpost clamps on the market. The Carver clamp features a full titanium construction, including a 6mm titanium bolt. This clamp has a 31.8mm or 34.9mm inside diameter and is suitable for most seat tubes with a 31.8mm or 34.9mm outside diameter.
As with all titanium-on-titanium interfaces, use Ti-Prep anti-seize compound to prevent turning your clamp into a one-piece!
