Adjusting the spokes is a real *****, seriously unless you have an excessive amount of patience get it done by someone else. You have to adjust each individual spoke to keep the wheel straight you cant just crank them all down, so basically you sit there spinning the wheel and making tiny adjustments to each spoke until you pulled the rim so that its spins straight. I get mine done (for my bicycle) at the local bike shop, i think it was like $50 for both wheels when i let them get excessively trashed (rear wheel was twisted so bad the knobs were rubbing on the frame). Also where did you find the price for that tool i own one and i think i paid like $10 for it (and used it once).
Really like the bike by the way. I wish i could have gotten a deal like that instead of trying to build my own.
