Silva (Campy) #25 SEAT TUBE REAMER FOR 27.2mm
So you want to be a pro builder ?
One of the features that separates the pro's from the hobby builder is the quality of finish left in the head tube and seat tube- where the customer or shop has to install a headset and seat pin. In the seat tube, an adjustable reamer chatters and leaves rough lines to potentially mess up the customer's fancy seat pin.
A precision helical reamer eliminates the problem with a helical shearing action that leaves a smooth finish and a rounder bore than an adjustable reamer.
