    New question here. Bottom Bracket?? Race Face SL Next Carbon Cranks 1x11

    Hey all -
    I've been searching this forum and the web on an answer about the Race Face Cinch Bottom Bracket PF30- http://www.raceface.com/comp/292/ban...ch-bb-pf30.jpg

    I just bought a new 2014 Epic Marathon and want to upgrade to 1x11. I really dig the Race Face Next SL crankset but I'm worried about the "press in" cups with external bearings.

    - Will the bottom bracket wear because the bearing outside of the BB (seems the force from the crank arm would be around the cups)?

    - Will the cups come out of the frame?

    XX1 or S-Works with Wolf Tooth may be the answer and easier. Hopefully, you guys can help.

    Let me know what you think or if anyone has any experience with this Race Face Bottom Bracket.

    Thanks
    - Jay

    Looks interesting. No issues with the external bearings. Shimano and SRAM (GXP) have been doing it for years with their 24mm crank BB's.
