I said "lighter" not weaker. Sun Rhino Lites & 1.9" tires. I ride XC & DH combined in same rides mostly. I have no desire to HikeABike. These tires I have now are like monster truck tires, look nice but not very efficient, if U know what I mean. No need for the thru axel either. I'm 42, and believe me, I screamed DH alot more than you probably. Been in the sport since '93.... Have a nice ride!
