Roberta, one thing to watch for: the minimum insertion line is designed for not-tall steerers so can be a little deceiving. Rivs come with quite a bit of steerer jutting above the headtube, which reveals itself to your eye as an adjusting nut with flats right at the headtube, then some spacers, then the other fixing nut on top of that.
What you want to do is get a general sense of where the insert marks are, then estimate down from that spot where the wedge is. The wedge needs to be firmly below the lower nut. Now here's where one tool comes in if you'd like to give it a whirl, I'll send you the correct Allen wrench no charge, I have a ton of them: Look straight down at the stem, you'll see a bolt. That's it, that's your adjustment for raising/lowering the stem. You get your wrench in there and give it a good tug counterclockwise to break the wedge loose, then pull it up 'til you see the insertion marks. At this stage if you have the stock stem it's probably WAY too high, so just drop that baby down, tighten the bolt again (good and tight, but not massively cranking on it), and you've adjusted your bike! If it's close to where you want it, pull up to get an idea where the wedge/bottom-of-stem is, then sink it back down to where you're confident the wedge is deep enough. Holla at me if you want the wrench at joeremi62 - gmail - com. Completely free no charge gratis, I got too many!
