42.9mm Bolt-On Seat Clamp

It is a non-standard size compared to the rest of the industry. I lend my bike to family members, often needing to readjust the seat to the point of not being able to back it out. The bolt is a small hex head and has been stripped out. Other bikes, including specialized, have options to replace with a cam quick-release. I now have to create my own after market solution.

Just bought a replacement seat post clamp for my new Como e-bike. I adjusted the original a few times and the bike tool the local bike shop sold me stripped out the bike screw. I just bought a replacement clamp and screw and also purchased the specialized specific torque tool. Highly recommend the torque tool since the Specialized screws are a little different size from most bike tools and it is easy to strip out the torque screws.
