having an sl5 with stock bb30 bracket in there . im using a ultegra 8000 crank so i have spacers in between there. never replaced a s works bracket so dont know how it works.

i would like to have a bb that already has that spacing on there. can i just bust the bearings out and put something like this c bear in? https://www.c-bear.com/nl/products/bott ... face-rotor
or do i need to remove the epoxied cup?

someone that done something like that before?

If you have a stock Tarmac SL5, its just a BB30 bearing in there with an outboard reducer cup to allow the shimano spindle... its just a matter of knocking out the bearings and installing what you want.. I did the ceramic speed 2 piece bb30 for shimano in mine, just screws togther. Ive since changed to Campagnolo, so just unscrewed the whole thing out and put it in my TT bike...

I think its this one you need:

In my 2016 Tarmac I used this one:

I was using a Dura Ace SRM in mine, but don't think the Ultegra is any different for setup? But I could be wrong..

Its a 2 piece design, the 2 pieces thread together and join in the middle.. you will need 2 BB tools that match the spline design on the cups.. push em in, thread em together... never creaked once!

Spun like crazy for me... what year is your frame.. you mentioned "epoxied cups" If its 2015 or later, my understanding is you don't have those OSBB inserts, and its a straight up BB30... post a pic of it if you can.. Id hate to lead you down the wrong road at the price these BBs are... I have the Tarmac SL5 Sagan Camo and its a BB30... the Sl6 and Venge use the exact same thing...
