GARY TURNER X BILLET BMX HOLEY SEAT POST CLAMP 31.8mm (30mm w/ Shim)
Billet BMX teamed up with Craig Turner to create an awesome collaboration featuring a custom designed Gary Tuner product line. These Billet Parts compliment all the hand made Gary Turner framesets by master fabricator Craig Turner.
This is our modern version of the 1980's Old School GT Holey seat clamp that was only made in 25.4mm (1") size. We made this in 31.8mm (30mm w/ Shim) to fit all the new modern aluminum 26"-29" framesets but we include a shim that will adapt to 30mm sizes also. We use a Stainless Steel Bolt and Customer Gary Turner Logo Round Nut so the aluminum clamp does not get stripped if overtightened. It is fully CNC machined and made out of 6061 T6 Billet Aluminum. The clamp is then anodized, engraved and assembled.
- 31.8mm (1-1/4") with No Shim for Newer BMX Aluminum Framesets
- 30mm (1-3/16") with Provided Shim Aluminum Framesets
- 6061 T6 Aluminum Full CNC
- Stainless Steel Bolt with Custom Gary Turner Logo Round Nut
