I put at least 100 miles a week on her for the last 3 months. I have been averaging 19.5 mph on 30 mile rides. This thing is a beatifully fast vintage bike. I do plan to upgrade the wheels very soon due to the rear having a 4mm bent hop spot from an impact years ago. Wondering how much better it will ride once that is gone, I get a vibration also in the 5th gear of the 6 gear cassette maybe because that gear is bent.
