We call the Stinger 7s Two Face: It’s ideal for sprinters but also for time trialing. Why? Because it’s super stiff without compromising weight and super aero without acting like a sail in crosswinds. So whether you’ve got Cavendish or Crowie on your mind you’ll love these lucky number 7s. 75mm deep. 700c Tubular Front: 745 grams. 700c Tubular Rear: 881 grams.
