1" Donut Seat Clamp - Chrome

$44.95

Full-radius donut seat clamp in 1" size, machined from 6061-T6 aluminum. Hutch donut seat clamps include a titanium cap screw as a premium feature. Chrome plated finish. Made in USA.

 
Fits vintage old-school chromoly frames that use a 7/8" diameter seat post.
 
Note: Hole is 1.000" diameter. This is designed to fit with old-school chromoly BMX seat posts that are 7/8" diameter and used in conjunction with frame seat masts that are 1" OD with 0.062" wall section. In an effort to reduce weight, some batches of vintage Hutch frames were made with a thinner seat mast wall section, thus requiring a larger diameter 22.6mm seat post. This clamp is designed to work with a proper seat mast/seat post combination that equals the correct 1.000" stack. Check for proper fit of all components. Refunds/exchanges are not provided for seat clamp damage due to improper components installation.
