    If you use these fenders with wider tires, you encroach on the clearance between tire and fender. We recommend 20 mm between tire and fender for safety. If you use a tire that is about 8 mm wider, you reduce that to 12 mm. The bike will be rideable, but it's less than optimal. I wouldn't ride a bike like that on gravel.

  • The 650B x 60 mm fenders are designed for 42 mm-wide tires, and their radius reflects that.

    So even though we'd love to sell you fenders, we don't recommend using the fenders we currently offer. Unfortunately, no other company offers fenders in the right diameter, from what I can tell.
