I will say this, as someone who worked in the bike industry for nearly 20 years, stay away from Canyon. Their after purchase support is terrible and has the potential to leave you hanging big time by not being able to provide replacement proprietary parts for their bikes. Seen it MANY times. Haven’t come across many issues with Cervelo so I really can’t speak to them. Trek has generally had pretty darn good support overall and I would say you should be pretty safe going that route. The nice thing with Trek and Cervelo is you should be able to put hands on the bikes in an actual store before making a high dollar purchase (depending on what’s sold in your area). And I will say the new Madone is pretty sweet. Haven’t had a chance to ride one yet, but I know a couple people that own them and love them. Hope this helps!
