Donn/Challenge got back to me about their “file tread” tyre availability:
“The Grifo XS (file tread) will be arriving mid to late July. This tread design will be available in the following configurations:
* Grifo 32 XS Tubular Black/Brown (black tread/brown sidewall)
* Grifo 34 XS Tubular Black/Brown
* Grifo 32 XS Tubular White/Black
* Grifo 32 XS Open Black/Brown
* Grifo 32 XS Open White/Black”
The open tread is the clincher version!
I’ll have them in stock when they are available!
White file tread clinchers!
I’ve also got a small handful of Dura Ace 46 tooth cyclocross chainrings available!
$120 each shipped in the conti USA!
So dope! And rare!
