I have my rotor Quarq available for sale. It is 172.5 length and the chainrings are 53/39 q rings. I got it last July so it is a little less than one year old. It probably has around 500 miles on it. The battery was recently changed. It worked great with my garmin and I had zero problems with it. I will post pictures up later tonight.
$1500 shipped
Also I’m located in Houston and would love to sell locally.
