thanks, i need to get that book. well i guess they aren't true then. they
are fine side-to-side but up and down there's a dent in the rear. dont
replace the spokes? i have already broken and replaced five of them, that's
why i want better wheels. i check the tension frequently and i mean it about
the roads. the bike lane i travel every day is worse than some single track
dirt trails i know...i would change the route but the bike lane is the
safest.
