How do you adjust this helmet?
(lemmy.nowsci.com)
Dumb question, but new to cycling, and the person at the store adjusted the height of the back via the tab. The Trek manual and video are absolute garbage, so we can't figure out how. Can anyone help?
Make sure as well that you bought the right size helmet for your head size. Ideally, it should stay in place even without the adjustment dial at the back (that just makes it even more secure). And you should have around a two finger distance between your eyebrows, and the bottom of the helmet.
