Challenge Grifo Pro Handmade Tubular Tire 700 x 38

The Staple That Sets the Standard

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. 

This particular variant is the 38mm size. It is AMAZING for most all racing you may do. 

This tire is a 38 in size. Currently these are legal in most all USA Cycling races (Not legal in Junior 17-18, U23, and Elite National Championships - Legal for Junior 15-16 and Masters National Championships). They are not currently legal for use in UCI World Championships across the board. This is the "PRO" casing meaning it is 300 TPI and is made of "SuperPoly" instead of Cotton. This is a Tubular Tire

Rob's Rating: "I have run this 38mm tubular for a few seasons and it always ends up being my most used and most popular wheel/tire setups in my quiver. I won my first race in 30+ years of racing on these. To say I love them would be a massive understatement. These are 38 so some have hesitation running them but it turns out they are LEGAL to run in just about every race you would ever enter. If you aren't planning on contesting the 17/18, U23 or Elite National Championships then you CAN RUN THESE. Buy them while you can!"

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"

Tim's Take: "Grifo is a great all season tire if you don't get rain/mud. Good on loose, loose over hard, dry and dusty, rocky and rooty. Fast on grass. Faster on pavement, Even works well in slightly muddy provided you have your pressures dialed. It is not a true mud tire. Has the ability to shed mud well depending on the conditions. My true choice in the Challenge lineup."
