CeramicSpeed 11-Speed Pulley Wheel Set

When you are serious enough to be searching for every way to reduce weight and friction from your bike and mechanical system, you will come quickly to your derailleur pulleys. Not so much for a reduction in weight, but to reduce friction to a minimum within the drivetrain. It may seem obsessive, but cyclists and triathletes can be obsessive about the details. It is one of our Type-A qualities. But seriously, many of us do look for every possible upgrade or advantage. It doesn't matter if you are a Cat 2 pushing for Cat 1 or pro, or if you are just the type of cyclist who has to upgrade, has to tinker, has to run latex tubes.

CeramicSpeed has been making high quality machined aluminum derailleur pulley wheels for over a decade. The state of the art ceramic balls used in these beauties are a cut above what you find elsewhere. Internal and external testing has shown a measurable drop in drivetrain resistance (the amount varies with system, gearing combinations, etc). The pulley itself is lighter than most stock pulleys and the sculpted wheel itself is designed for the drivetrain it is intended for. Your pulley wheels spin the fastest out of all your bearing set-ups. It makes sense that a high quality bearing and pulley wheel can reduce friction and save you wattage over a long event. Keep in mind that these bearings require lubrication. CeramicSpeed provides the proper oil and instructions you will need to keep your bearings spinning easily at high speed. Step up, be obsessive, and get the most you can out of your equipment with CeramicSpeed Derailleur Pulley Wheels
