while I'm guessing you're probably bored with my old Raleigh, it has the best-functioning seatpost clamp I've ever monkeyed with. Tightening the bolt is not what clamps the seatpost - it's the tension of the lug itself. You take a big-blade screwdriver and spread the clamp - you can slide the seatpost anywhere. You release the screwdriver spread, and the lug bites the seatpost. Tighten the bolt snug (no torque) and you're done. It's been working this way for 38 years through 3 different seatposts.
