Bike has less than 450 miles. I mainly used it on the road and saw very little gravel use. I swapped the the original tires with a better set, Maxxis Rambler 40mm. Perfect for both road and gravel use! You can go to Niner's site directly to read the specs for their 4 star build, but it's their GRX800 gravel specific groupset (2x). Size: 50 Not willing to ship, local sales only. Again, LOCAL SALES only. If you have any questions, just ask.
