OP Here: Got it, I can ride hands free and thank you. Rear wheel off a bunch. Took me a couple of days to figure out how to DIY alignment check. Tied string to front wheel spoke - wrapped around tire and threaded THRU spokes front and rear so as not to touch any. Rear wheel tread wear results were obvious, I just assumed tire wear due to it being drive wheel and carrying extra weight. Bet I just added 2 mph to daily rides. Thanks again.
