I need to replace my group set after totalling my brifters and handlebars in a freak accident. I could get this used (in great condition) SRAM rival groupset for 280.00 USD from a local seller. He says the levers are as good as new and there are only minor scrapes on the crank set. He's only missing the brake set. Should I do it or am I going to regret buying used carbon/sram components? I don't live in the States and these kind of shit is insanely expensive to import.
