One versatile clincher to ride all season.
Challenge's Grifo Open has been replaced with this more affordable, nylon casing equipped Giro Race. This updated model still features the tried-and-true Grifo tread pattern, with low-profile knobs that are not only great on fast grass courses and hard-packed gravel and dirt, but aggressive enough for serious mud. At 120 threads per inch, and a respectable 330g weight, the Grifo Race won't slow you down in competition either, making it an excellent affordable all-arounder.
The Giro Race is available in 700c x 32mm (33-622 ISO). It's available in black with a folding bead and 120 TPI casing. Challenge lists a claimed weight of 330g, and the recommended pressure range is 40-75 PSI.

I just got a Focus Paralane gravel bike that came with clement x plore mso tires. With all the rain we've had , they didn't give me the traction I needed so I got the challenge grifo .The tread is aggressive enough for loose rock and climbing up muddy hills. I have to ride pavement 3-6 miles to get to the different trails I ride and they roll pretty well getting there. I have 200 miles on them and they still look almost new.
