Description
Bottom bracket Cycling Ceramic bsa shimano
- The CyclingCeramic crankcases are combined with low friction ceramic bearings that are more durable than standard bearings.
- The high quality finish of the crankcases allows them to achieve high performance. They have been designed to offer a lightweight assembly and, thanks to the design of the seals, allow maximum protection.
- The extreme hardness of the CyclingCeramic balls results in a bearing life that is 4 to 5 times longer than standard bearings. The special grease keeps your bearings sealed and protects them from external elements that can hinder proper operation.
- Silicon nitride balls are used to improve bearing performance. Ceramic balls are lighter, stiffer, smoother, harder and more resistant to corrosion.
- They require less lubrication and have lower thermal expansion than their steel counterparts.
- The balls are continuously polished for 45 days to obtain rounder and smoother balls.
- This results in a smaller contact area.

- Does your bike crack when you press hard on the pedals, has the pedal movement lost its fluidity or has it become sloppy? The symptoms are clear: it's time to change your pedal box. Like all the parts that make up your bike, the pedal box and especially its bearings are subject to wear.
- Its replacement is a simple operation if it is well prepared, indeed the multiplication of the standards of bearings, pedal bearing and frame can discourage some. We will try to guide you through this jungle of standards.
- The pedal box is the interface between your pedal box and your frame, so the first thing to do is to identify which pedal box you want to fit in which frame.
- We advise you to dismantle your original box to measure with precision the dimensions of the pedal box of your frame. This compatibility is given as an indication, there are also boxes "adapters" which allow to mix the standards.
