If that didn't get your attention...

I'm actually looking for G springs for Sachs licensed New Success ergopower shifters. I can't get the shifters to stay in the lowest gear, they pop back up into the next gear. I've been told G springs will solve this problem. Correct me if I'm wrong. I have two sets in need of rebuilding. I think these are the sexiest brifters ever made, the way shift levers ought to look. Thanks for any help.
