I build all of my wheels. After doing it for more than a few years, it takes about 30 minutes to lace the rim and another 40 minutes to finish and true the wheel. I spent about 30 minutes last Monday working with a Co-Op worker who was trying to correct a wheel dish that had a bunch of wobble after his attempts. I explained how to correct for dish and then how to correct wheel hop. He learned enough to do some minor work in the future and in just a half hour. Learn to build wheels yourself you won't regret it. Smiles, MH
