I recently (3 weeks ago) bought a Giant Roam3 and the disc brakes rub when the wheel is centered and mounted in a vertical position. The only way I can mount the wheel so it doesn't rub is to tilt the wheel which to me seems mechanically faulty. Shouldn't the front wheel be vertical or as close to vertical as mechanically possible and align with the brake? Is this acceptable? It seems to me that the front wheel should not have to be tilted, or uncentered in order for the disc brake to align. Thanks for any advice!
