Ceramic Speed bearings are said to be the lightest, smoothest, and most durable bearings available on the market. Whilst you read about pro teams replacing stock bearings with ceramics, Ceramic Speed is the company they depend on.

As regards to each and every single powermeter ever produced, whether it is a hub, crank, or a pedal, it must be serviced at some time over its operating life. Until now, you have needed to surrender your precious meter for days, or even weeks, to get it worked on and returned. We have witnessed power fiends get despondent and desperate, trying to determine how they are able to source a spare powermeter throughout the absence. Now, you are able to get a spare cap with all the electronics before you send yours in. And shipping is simpler and less expensive Whilst you do not need to stick a wheel in a box. Any other improvement that comes with this change is a single CR2032 watch battery powers the transmitter. These batteries are easier to source and replace than the two 357 batteries found in the older hubs. The battery must last for approxima…
