Some years ago I obtained from a friend the pieces to build an homage to Masi. I have am a 99th percentile body type and in 35 years have never found a Masi to fit me. But I've forgotten-welcome to old age-an important detail. 14mm or 16mm seat stays. Could an obliging Masi owner measure the stays below the scallop? Many thanks in advance.
