Wheel building skills
I was in my LBS and asked the owner if he stocked Mavic rims. He said he coud get them and of course asked if I planned to build up a set of wheels. I told him "yes" and he smirked and the mechanic in back let out a laugh. He then proceeded to tell me one of his distributors could build me a set exactly the way I wanted and my chances of success where slim. He also said if I failed his mechanic could try and fix it or they could send them out. Is building a set of wheels some kind of black art or is this guy full of it. I could understand if someone had no experience but I only use the LBS to do stuff I can't justify buying special tools for.
