I am looking for Zipp vumaquad 52T chainring to race in junior category ! if i dont find it i have to use Ultegra 6650 34T-52T it might not work and it is much heavier than Zipp crankset.
So far i have found Rotor 36T-52T and also Fiber-Lyte 52T, Fiber-Lyte is cheaper but how much kilometers i can ride on a carbon chainring till it wear out ? is it durable for racing ?
Rotor chaingrings is too expensive for me and i dont got money for 2 chainring that cost 250dollar.
Does anyone know cheaper alternative ?
I hope someone can help me !:)
