    Any suggestions for a stoker stem replacement?

    Just bought our first tandem and want to change the stoker bars. That requires a stem change - the seatpost is a 27.2 and the bars I want to instal are 31.8; does anyone know a manufacturer of this diameter combo?

    It might be easier and cheaper to purchase a bar that has a 26.0 clamp. I do not know if the combination you are looking for is available or not.

    This should work for you. You will need a shim, but we have used with 27.2 seatpost with great success.

    That is a good choice if you want an adjustable stem, however if a standard stem will work then you can buy a new stem that is the correct length/angle and use a shim to adapt it to your 27.2 seatpost. That is exactly what we did.

    Control Tech & Dimension both offer 29.8 w/shim x 31.8

    Co-Motion's is probably a re-branded Dimension.

    Depending on how much length and rise you need for the stoker stem, you may also be able to use a longer (150mm) threadless stem.
