Hi all, On the First Day of Spring I got up at 6 am and while waiting for the temperature to reach 35 degrees F, I installed my Nikon 170 to record parts of my ride. Several people have been commenting on the mid-drive noise, comparing it to the noisy Bosh or other systems. Granted it is not as quiet as the Turbo S I test drove, but from just sitting on the bike it is hard to hear any noise at all. Also, with skillful shifting there is not any mashing of the gears and chain. The more I ride my Turbo Levo FSR, the more I realized I made the right choice for me. If you are interested here is a video to watch, it's not 720p for some reason, but you can hear the bike working well. Enjoy.
