What a tool... The wheels are untrue by 4mm and 2mm. If that was me, I wouldn't give a shit! Lol, if the wheels work with maguras without rubbing, they're true. 4 and 2mm untrue.. That's exactly the type of shite bike shops tell you to suck your wallet dry. If they said that to me, I'd've gone, 'Ok, I'll true them more when I get home, thanks.' I'm surprised the shop didn't say, 'Oh, yeah, erm, you seem to be missing a seat, we can install one for you for the low low price of £100!'
