Great for S&S travel bikes!
Bought a few of these for my S&S coupler-equipped travel bikes. Really handy for packing the bikes. I can pull the stem off and not worry about messing up the headset/fork adjustment. The product is nice looking and fairly light (not too much heavier than a regular spacer). Really no downside to this product if you remove your stem with any regularity.

Can this Problem Solvers Locking Headset Spacer be used with a carbon steer tube? Should a friction paste be used (aluminum to carbon)?
