For Sale: Mavic ellipse rear wheel

had the same problem - stripped both lockring threads.
went and bought some industrial alternative to locktite.
glued one cog and a lockring. probably forever.

This is what I'd do... In fact would have done if I hadn't just got a Royce wheelset.

it's a great price, just buy a decent cog with a sencible tooth count, ride it into the ground and youve got an awesome deal. Another classic LFgss bargin.
