WARNING! This is for damaged frames whose Bottom Brackets have become oversized. DCTech EVO Oversized for Shimano & SRAM is a high-precision bottom bracket designed for bicycle frames with a worn out bottom bracket shell. Over time, press-fit models can expand due to wear, causing improper fit, annoying noises, and an uncomfortable pedaling experience

Our innovative solution extends the lifespan of your bike. This model features cups that are 0.1 mm larger than standard bottom brackets, ensuring a perfect fit once again.
