    Lefty stem swap question

    I have a 2009 Rize 3 Medium frame with an 90mm 5 degree stem. I would like to swap the stem for a 20 degree (need to get more upright) but I am not sure if I use the same 90mm reach or do I go longer since the angle actually decreases the forward reach. Hope someone has some insights. Thanks!

    Additionally, I have already swapped my bars to a higher rise so I need to achieve additional rise via a stem.

    You will get 23.6mm higher stem height with a 90mm stem with 20 degree rise.

    And 5.4mm closer to you.

    Kuan is right on the money.

    I'll be changing my 100mm +5° XC3 stem for a -5° to get lower and further forward as I went from a 600mm flat bar to a 680mm rise bar with more sweep... I think I'll wait for the new 2011 stems.

    Just make sure you loose the clamp bolts BEFORE the steer bolt on the bottom of the stem when you take it off.

    When you put it back together, tighten the steer bolt BEFORE the clamp bolts.

    You will need a special tool. Here's the basics on how to make one. I've never tried it. Make sure you seat the bottom race properly because it may unseat when you remove the steerer.

    Lefty steerer removal tool = D-cell Maglite
