o.k school time!obviously the mistake is 5 spoke 7 spoke thing,with regard to 17" rims. you'll actually find he is correct on this matter. a standard 20" wheeled bike will have a rim diameter of roughly 17". the rest being made up by the tyre!go check if you don't believe
but we're talking bikes not cars!you and me are in the same industry dude! cars use a different philosophy on tyre/wheel measurement. when it comes to cars you by a 17" inch rim and tyres to fit, or 18" inch rim with tyres to fit. it's the masses who say they've got 17" wheels because they're uneducated on the subject or just that they're terminology is wrong!
