Thanks...its not so much the chainrnig selection I'm worried about cause I've already upgraded mine to a Vuelta 130 BCD 60T ring which I like and I want to keep using that. Now that I've upgraded the chainring I'm thinking of ugrading the crank arms and the bottom bracket to fulfill an entire crankset and BB transformation... I'll keep scouring the internet to see if I can't find a 175mm arm 130BCD spacing crank arm set and a matching BB with 110-116mm width thats moderately to very lightweight.
