Okay, got another question from hubby here. He has a bad left ankle, & he's caught himself changing gears with the heel shifter, but he has realized that he sometimes forgets to let up on the shifter. So, do the gears change and release immediately, or is he on the verge of causing big problems. I know it is probably not good, but we are hoping that it isn't too damaging. He's only noticed it a few times recently when pain levels are high, but we thought we would check. Thanks!
