I’ve had a Yeti and an Ibis which I’d consider boutique. They were great, fast, high quality bikes.
I have also had a few Treks that really aren’t as ‘high end’ including my current bike. I think I’m having more fun on it than I had on the others…That might be because it fits me better or that its a 29er but thats a whole other thread! I never found any magic feel in the more expensive bikes but of course they were good!
Like you I think the Canyons are amazing value but for me the geometry just isn’t right on paper and as I can’t see one in the flesh they are out. The Rockys look amazing in person-the one I went to see today was really impressive!
