The clamp on my seatpost looks exactly like this:

The LBS put it on and it fits REALLY tight. I'm concerned that it might be damaging to the seatpost tube. I took it off once to do some maintenance and had to literally hammer it back on later. The seatpost itself fits, but only because I had to sand off about 1.5mm of the inner seatpost tube edge so that it was no longer gouging into the seatpost. I think the clamp on there is the "28.6mm Electra Clamp for Steel frames". My bike is a Kona Smoke, and they take 29.8mm clamps. Should I continue using the 28.6mm clamp? The only one I could find in my exact size is the "Axiom Trekk Seat Collar w/Rack Eyelets". It doesn't look very strong though, unless it's NOT supposed to actually doyble as a seatpost clamp. Advice?
