Bungee Tension

[Rolph Muller <rolph@globalvt.demon.co.uk>]

I set my bungee tension a couple of months ago to what I thought was the
right tension - any tighter and I had problems getting the wheel down.
After what is I guess about a couple of months sitting on the wheel, the
wheel will hardly go all the way up using one hand i.e. the bungee has
stretched without a doubt. Anybody else had this problem? I suppose
there may be some lift assistance when flying. Is the tension going to
need regular adjustment?
