I’ve been riding and racing with the Serfas Krest 9r tires since November. I initially installed these tires on my KHS Solo One 29er for training purposes.
Well, I was really impressed with the tires that I decided to install the front tire on my KHS Flagstaff 29er and race SuperD with it. Why just the front tire? Well, I have two 29er bikes and only one pair of tires! The Krest 9r tire hooks up really well on any terrain and in all conditions. I’ve put over 100 miles on these tires and I can say that they hook up well on dry, loose, packed or muddy terrain.
Integrated Flat Protection System Provides Superior Puncture Resistance
Tightly Spaced Lug Pattern for Constant Traction
Center Lugs are Ramped for Low Rolling Resistance
Fast and Predictable Cross Country and All-Mountain Tire
Great for All Conditions
Pros:Lightweight, hook up very well, roll fast, durable, inexpensive and they come with flat prevention.
Cons: Tires are not easy to find at your LBS.
I learned that playing around with tire pressures will get you the most performance out of this tire. For hard pack terrain, I would ride at 40psi, for loose, rooty and rocky terrain I lowered the pressure to 30psi. Although the lowest pressure that manufacturer recommends is 40psi, I never encountered an issue with the tires riding at 30psi.
Recommendation:Even though Serfas is little known for their tires, the Krest 9’r really impressed the heck out of me and I would definitely recommend them to any 29er enthusiast. In fact, I’ve just ordered a new set for both bikes from here for $15.93 per tire!
