I put a deposit on a 2015 Specialized Sirrus Expert Carbon! They are not yet available, but I will have one as soon as they are. I am still a bit concerned about the microshift shifters; however, by bike shop said they will work with me to replace them if I do not like them. I really liked and wanted the Pro Carbon, but decided against getting one when I realized the cost of replacing the rear cassette. Given the number miles I ride in a year I would have maintenance costs of about $500 every other year. I also considered the Cannondale Quick Carbon 1, but the longer top tube on the Siruss fits me better. Thanks for your help.
