    Size of RT1000 Stoker Stem Seat Post Clamp?

    I have an OEM 1999 Cannondale RT1000 stoker stem. The seat post clamp uses a shim to fit the 27.2 mm captain's seat post. The surface of that shim is scratched, so I cannot read the OD size of the shim. (See the photo.)

    Can anyone tell me the OD size of the shim? I have tried to measure it, but it could be a few common sizes, depending on how hard I squeeze the shim together.

    Thanks!

    Very accurately measure the wall thickness. Multiply times 2 and add that to 27.2.

    Odd thing though, I was unaware that any Cannondales of that era used a shim to achieve 27.2.

    FWIW, the best seatube shims I have found for 27.2 are the Thudbuster manufactured parts. Far better quality than Problem Solvers brand on account of being longer and anodized.

    And most important, someone special that enjoys them with me (except the KTM's)

    Great tip... thanks!

    Here's a picture of the stoker stem.

    It's so nicely made that it's actually a pleasure to look at or to hold!
