From the website, the stock kilo has 0 degrees rise, the stipper has 8, and the soma has 7. I'm new to bikes. Is a 45mm stack height the height of the clamp? If so you can adjust that with removing spacers right? I tried measuring the length of my stripper stem and got 90 or 100mm (I got 95 but i must have measured wrong?) Again I'm new, so maybe take my word with a grain of salt. I was thinking of buying this stem too. Tell me how it goes.
