Discovered play in my Cassette on a new Medeo T10+at 200 miles. Mechanic torqued to specs and confirmed Deore hub is defective. Will contact dealer today for warranty replacement. For the life of me, I don't understand rim sizes for my tires. Bike came with 28"x 2" Schwalbe Marathon tires. No idea what wheel size accommodates this tire. Gazelle specs are generic at best. Used to be easy. Not any more.
