Reviews & Ratings
28:14The reviewer tests the L-TWOO R9 2x11s Aluminium Road Rim Brake Groupset (ST-R5011), noting it is the cheapest 2x11 speed groupset available. He praises the derailleurs for their build quality and shifting performance, but criticizes the shifters for several design flaws, including a missing washer that can cause the clamping bolt to chew through the plastic, lack of a hard stop at the end of gear range, and a plastic lever arm that can jam against the thumb shifter. Despite these issues, he finds the overall shifting acceptable once set up, but recommends the MicroNew shifters as a better budget alternative.
