Glad to see there's some many others that love the Sirrus! I picked up a 2017 Comp Carbon and am absolutely in love. The bike is so comfortable yet SO fast. Roadies are always wondering how a guy in gym clothes on a hybrid bike is pulling away LOL. Been having some fun tinkering on this thing and making it my own. Excited to run a 1X setup someday and get some nicer wheels. Have some Michelin Power Endurance (700cx25) tires coming and will report back on how they work out on this bike. Cheers!
