Five months ago I got a great carbon fiber bike from 2016, a Kestrel Legend SL. I live in SW Florida where there are no hills. I try to ride every day, leaving from my house on a 9-10 mile loop. I’ve gotten a lot stronger since I first started this exercise routine and now average 18-20 mph. So I’m really hooked on the exercise aspect. But I also like the bicycle itself and have made several improvements/upgrades along the way….new narrower carbon bars, new aero carbon wheels, new carbon seat post, and new carbon saddle. The result of these changes reduced the weight of the bike by one pound. Just love the bike and the thrill of riding it! Even though it is kind of ‘old fashioned’ with toe cage and strap pedals, rim brakes, mechanical shifters, no power meter, and tubed tires.
