Yes, always. While most bikes come with pretty good components fitted to them these days, I change some due to personal preference. For example, handlebar grips are a big one for me. I often switch mine out to Burgtec Bartender Pro grips, I actually really like their new soft compound grip actually. I don’t tend to swap parts from MTB to MTB though. There are so many standards these days, that it’s not as easy to swap items over as it was.
