Aluminum alloy seat post clamp similar to the old Tuf Neck clamps.
Color: BLACK ANODIZED
Size: 28.6mm (1 1/8 inch) which fits many current BMX steel or chromoly frames that use a 1" (25.4mm) seatpost.
This is NOT an old school size (very few 1980's bikes used this size).
Brand new, in perfect condition, never used or mounted.
These were purchased in bulk so there is no retail packaging.
