Put the 29x2.6 on my Surly Krampus to race in a 24hr race. Typically my Krampus is set up for bikepacking with heavy DH tires. These tires immediately dropped about 2lbs from my bike (with Cush core inserts) and transformed my bike into a race ready XC slayer! Got about 100 miles on them so far and couldn’t be happier! We’ll see how they ware, but with the Black Friday price of 1/2 off who cares. Light and grippy on the hard pack! 2.6 is perfect on a Krampus. Love Kenda! I’m gonna stock up on these come the next sale!
