I've got almost 11,000 miles on my GR260 that was a year old this past 4th of July was the first ride. About half on the original I-9 / Carbon rim 700c wheels and half on 650b with SON dynamo in the front.
The bike has been great with Ultegra but I did change the rings to Absolute Black oval 30/46.
