Reamers

The holy grail of framebuilder reamers for seat tubes is a solid spiral flute hand or chucking reamer. These are very hard to find in the fractional metric sizes common for seatposts.

Cyclus Shell Reamers

German bike specific tools. Nice.

The handle costs $81.70 and each shell reamer is another $47.00. Any common size is avaliable. Available throught Bike Tools Etc.

I wish that the reamer was spiral fluted and longer. A longer lead in would also be nicer.

They say that a regrind could be $24 for a chucking reamer $40 for a hand reamer, if they do not have to take too much material off.

27.2mm

Probably the most common size seatpost in the industry for steel bikes.
