Challenge Grifo Team Edition Handmade Tubular Tire 700 x 33

The Grifo is absolutely one of the best "mid" tires around for racing cyclocross. It excels in racing courses that have a mix of terrains such as grass, slightly loose dirt, rock, etc. It performs well on grassy off-camber sections. It doesn't rob you of straight-line speed on hard pack or grassy fields. While it can handle some moisture such as early morning dew for those early races as well as some mild slick mud it can be said that soft, wet, or overly muddy conditions are not it's forte. 

Rob's Rating: "The Grifo has wiggled it's way back into my heart after years of not riding it. If you are in an area with a lot of hard soil or grass crit style courses then it is quite possibly the best option all around"

Leah's Take: "I think the Grifo is fast in a straight line and has reasonable mid range traction in most non-muddy conditions. My personal tendency is to prefer a tread with more aggressive side knobs such as the Flandrien or Baby Limus in the same conditions"
