offset/setback seatpost for 30.0mm seattube?

[jlc115]

Does anyone see any 30.0 mm seatposts online in stock that have an offset? I have a thomson 30.0mm seatpost but they don't make an offset version for this diameter. Most of the posts I've seen online are for the more common diameters.

How much set back are you looking for? Race Face and Kalloy make a 30.0 size w/ a slight offset.

You might also try a seatpost shim. Several aftermarket manufacturers make shims for many conversion sizes. Problem Solvers is just one example.

Some people have good luck with shims, others have slippage issues. For about $10 its worth the experiment.
