Nearly all builders assemble the tubes of a frame on a large steel flat plate called a jig. Each joint is heated to brazing temperature and a bit of brass is applied. This is known as "tack brazing". The frame is then put on an alignment table and made straight. The frame is then put in a stand much like bike shops use to repair bikes and the lugs are completely brazed up.
While this is the technique of nearly all builders, it is not the technique of Mondonico. Tack brazing requires that the tubes be heated twice, robbing the special, exotic cycle tubes of some of their special qualities. When the tubes are assembled on the jig, Mondonico drills each lug and inserts a tapered steel pin. Then the frame is aligned and brazed up. The joint is heated only once, preserving the resilience of the Columbus tubing that Mondonico uses. The pins are then filed flush with the lugs. Obviously, this is a vastly more time-consuming method. Feel the inside of the tubes of a Mondonico frame at the bottom bracket. You can feel the pins, your guarantee that at least one craftsman is dedicated to making the best, not the most.
interessant wären der durchmesser der sattelklemme, ob eben was auf den ausfallern steht oder wie das tretlager von unten aussieht...von gravuren ist das teil ja scheinbar gänzlich befreit ^^
