I recently bought a frame only 06' Heckler from another forum member. It didn't come with a seatpost and I didn't want to get one from my LBS in order to save cash. I checked the Santa cruz website and it told me that I need a 30.9 seatpost, so I found one for sale. I bought a Syncros Derived 30.9 seatpost for a good price and after I get it home it doesn't fit in the seat tube. Any suggestions? Perhaps the frame isn't an 06 and the seatpost size if different than on the '06 website? Did earlier models have a different seatpost diameter. The frame could only be a 05 or 04 at the latest.
