more setback than a non-setback post? or more setback than your "standard" setback post?
I ask cuz the thomson isn't really set back that much. Something like 1.5cm to the front of the clamp. a "typical" setback is somewhere around 2cm.
Now there are ridiculously setback seatposts too. Like the Titec Hellbent (is that made anymore? it's damn ugly). The Look Ergopost offers 3 different setback distances (up to 3cm I believe). FSA make a few posts with large setback. As do RaceFace.
Even a cheapo Kalloy has more setback than a Thomson.
but if you wanted more setback than a straight post, then ignore me.
Thomson makes sweet posts.
