    Default Shimano crank x Phil

    I have a Shimano FC-R8000 and I have Phil threaded external BB cups, and they look very thin to me but I do not have a Shimano road BB here for comparison - the Phil cups are 10mm thick externally

    Had anyone set up this combo?

    The cranks seem really inboard and Phil says "consult crank specs" but I cannot locate any re: BB spacers and I sure think that stock Shimano cups are thicker then 1cm

    68mm shell

    THANKS !

    This help? I can’t find a BB, despite having 15 of them somewhere here. I do recall the cups being about 10ish mm thick, though, from base to face of cup.

    Shimano road external bottom brackets for threaded 68mm shells are 11.3 mm per side from the shell face to the outside edge of the cup. Symmetrical for left and right cups. Thicker than the MTB version, strangely.

    Steve,

    Just installed this exact combo on my my most well used gravel bike, replacing a completely shot dura ace unit. Works perfectly.

    Interesting discussion. I've been tossing around how to tune the deck height of a external BB as well. Wave washers will only do so much.

    I've used a thin cassette spacer to fine tune the chainline. Wheels manufacturing sells spacers in various thicknesses as well.

    Same here - Wheels Mfg spacer on an older frame with a BB shell a touch narrow for Campagnolo Ultra-Torque spec that resulted in too little compression of the wavy washer. Worked (and continues to work) perfectly. https://wheelsmfg.com/products/botto...p-spacers.html

    Thank You !!!

    Also, curiously enough, it keeps saying in the literature "FOR 70mm BB SHELL" so I reckon this all buys me some room to adjust the chain line with WMF 1mm spacers - looks like I already gained 3mm of clearance and I sure can use it

    Follow up - the newer Ultegras were just too "inboard" - the crank ends are thicker & closer - old 110 BCD cranks x Phil works awesome though - super doesn't hurt that it's a touring bike with not too short of stays as it's to run a 2.1" tire
