Conservation of angular momentum -- spinning a bicycle wheel in space

[abdossamad2003]

Suppose we have a rotating body like a bicycle wheel in space away from gravity. This body stops after a while due to friction between the wheel and wheel axles. Is not the conservation of angular momentum violated?

If it's just the wheel, then there's no axle exerting friction and the wheel will rotate without slowing forever. If it is mounted on a non-rotating bike, then the bike will take up the torque and begin rotating, conserving angular momentum.

You are wrong to say that the body stops. As per @Halc's answer, the wheel slows and the axle spins up until both are rotating at the same rate. Then the wheel and axle continue to spin eternally, at rest with respect to each other.
