Specifically developed for use with SRAM road, gravel or mountain bike (MTB) rear derailleurs, these jockey wheels are a great way to breathe new life into your existing set-up. They feature a reliable Grivory EMS construction, which is a composite material provided by EMS Swiss with a 40% glass-fiber mixture. BBB has also kitted these out with a narrow-wide tooth profile for ultimate chain retention wherever your next adventure leads you. Another highlight is these are equipped with low friction ceramic bearings for ultra-smooth glide and exceptional durability. Coming lubricated with special ceramic light oil, these deliver extra smoothness for a wide range of riding disciplines.
The Rollerboys will make your bike ride so smooth that you will never stop anymore! The composite material is strong and durable and the special teeth pattern makes sure you can shift to a higher gear with the speed of light. The ceramic bearings make sure your pulleys will roll so smooth that you never want to stop riding anymore. High-quality pulley wheels are a must-have for every serious bike rider, with the RollerBoys you are good to go.
