Thank You for this tool, from -6 to -17 on 90mm long stem, it seems ca. 17mm to be gained - only and even... (Definitelly not 35mm!
Pity that Enve Does not have this -17 version..
What would be better for 90kg rider? Extralite or Mcfk? Zipp is definitelly to heavy...
Another, quite brave option, is new upper Lefty Clamp - mounted ca 2cm lower than oryginal...
What do think?
And last but not least - will the travel change from 100 to 90 influence something?
If you're 90kg and not under 10% bodyfat, the ~70g is not going to matter. There are not many very aggressive stem options that are light. An old Ritchey 4 axis would probably be the lightest, but they were kind of flimsy. Zipp, 3T, Deda, and a few others make fairly aggressive stems and after the Ritchey the 3T team might be the lightest.
My Extralite stem at 73kg was flexy as all hell. I would not want to use it for a MTB.
Don't take me too seriously. GramzStrava
