Where can i get one ??? I will need this for my intentions of doing long highway runs. Also, ive been hearing loads of info on highway gearing for constant speeds between 60-70 mph without over revving/heating. What is a choice that we can safely agree on ??? Sorry to keep pounding this, but i would like to make one purchase of another set of sprokets if possible. Thanks alot for all the replies....sometimes this forum has too much info !!! LOL !!!
