Or what I ordered wrong? S-Works Venge 2014 has Ceramic Speed Bottom Bracket - as far as I understand ALL new SPECIALIZED Road Frames have OSBB? Is that right?C-Bear: "For frames with alumium inserts epoxied to the bottom bracket shell, convert it to a BB30 shell. For virgin carbon bottom bracket shell use OSBB61-86 Race bottom bracket." Daniel | 03/10/2015 Question: Do you have a solution to eliminate the bottom bracket problems for Tarmac S-Works 2012? My Sram bottom bracket is making a lot of noise, and this is a common problem for these frames.. Reply: C-Bear has eliminated the delrin cups to prevent creaking and damage to the bottom bracket shell. Bearings are housed in aluminum cups that are pressed into the frame.
