Canti posts have the spring tension pin location on the outside of the stud, not on the inside like almost all others in existence. The trek site and another spec site show diacompe 981 or shimano AT 50, niether has the pin location on hte outside. Bianchi typical location, Trek not so typical. This is a parts bin(except for tubes/tires) city/commute bike build for my 14yr old nephew. Any infor much appreciated.
