Oddly enough no, or at least, not after they;ve been on the bike for a while ( I am a serial fettler, and also hate narrow bars). If I put some wide 780’s on for a change and then go back to them, they do feel really narrow and odd, but after a few minutes, completely natural and I wonder why I would ever want to ride anything else. The loops are not noticably wider, just longer in the grip position. I do sometimes dream of a really wide Jones bar, but then I am a bit of a handlebar tart. 🙂
