$60 · Chainring set - ROTOR QXL Oval Aero - TT, Tri, Road

Chainring set (52-36). Used for one test ride. So I purchased a larger set. They are working well for me as I specialize as a time-trialer (TT). May have a slow cadence, but push large gears comfortably. QXL chainrings are most noticeable when riding in conditions of high power delivery and consistent maximum (peak) effort, like time trials, sprints, breakaways, etc. "A Q-Ring gives a silky-smooth "perfect spin" by smoothening out torque variations and making better use of your strongest muscles." I paid over $130 for the set. Asking only $60
