I am a 76 year old blood cancer survivor, thanks in large part to research funding provided by the Leukemia & Lymphoma Society, of both aggressive and slow growing non-Hodgkin lymphomas. For 10 years I have raised funds for LLS by riding the Scenic Shore 150-a two day ride from Milwaukee to Sturgeon Bay, Wisconsin. Last year the event raised over $2,000,000. Frame on the Roubaix is 56 cm with Shimano 105 components and carbon front fork The Sirrus Sport frame size is medium. I live in Oro Valley, AZ. Contact 608-886-4362. Thanks…Roy
