Race tires for cyclocross / gravel.
A mix of Donnelly PDX and MXPs and a couple Vittoria's thrown in.
Most of them were used a handful of times as a tubeless setup for racing.
These run about $70/each new.
Selling all 13 of these tires for $300.
If you race cross and have an extra set or two of wheels... these are great.
Or if you just like having knobs for your gravel bike tires - tubeless ready.
