It's gone!
Marc Parnes Universal Wheel Balancer
Used Twice
Check out the website: www.marcparnes.com This is the correct balancer for the GS, plus it will work on MANY other makes/models of bikes.
$50, plus $8 shipping
I have become unable to do heavy maintenance on bikes, so I'm moving this tool on to someone who can use it let me know if interested.
Thanks,
Marc
