I noticed about 1/8 inch movement when I push moderately side to side. I checked the wheel bearings and they don't have any noticeable play. Pulled (and cleaned) the cassette ... nothing out of order. No broken spokes or out of tension checking them by hand.
Bike and wheels are 1 year old with 3k miles on them.
Any suggestions or does it finally need some lbs tlc? Thanks.
