Collection: Cema

When every watt counts and marginal gains can be the difference between victory and defeat, it's the small components that really count. Cema is a specialist in ceramic bearings and bicycle components, developed for riders with a focus on efficiency, speed and durability. Their precision-machined bearings are among the best on the market and are used by both professionals and ambitious amateurs. At Transition Zone, we have put together a selection of Cema products that match the demands of triathletes, gravel riders and road cyclists alike.

Cema's ceramic bearings significantly reduce friction compared to traditional steel bearings and help you transfer more power directly to the road. This means you save energy and potentially ride faster and further - without changing your training level. That's why Cema has become the preferred choice of riders who want to optimize their equipment down to the smallest detail.

Cema is known for their uncompromising approach to precision and quality. Each bearing is made with ceramic balls that are harder and lighter than steel, and that resist wear and heat generation in a completely different way. The result is a more efficient roll, better durability and less maintenance. This makes ceramic bearings from Cema an obvious choice for those who want to optimize bottom brackets, wheels or pulley wheels.

Cema's products are available in different quality ranges, so you can choose the level that best suits your ambition level and setup. Whether you're building a new triathlon bike from scratch or upgrading your existing racer, a set of ceramic bearings from Cema will give you a noticeable difference in performance.

At Transition Zone, we carry Cema products to suit a wide range of setups and needs. Whether you're riding on tarmac, gravel or in an aero position for an Ironman race, low friction and high reliability are essential. With Cema ceramic bearings, you get a component that can handle intense loads without compromising speed or durability.

This is especially true when you are riding long competitions and need a setup that runs as smoothly as possible, even under heavy pressure. Cema's products are developed for this very purpose - and they deliver. It is not without reason that Cema is used by riders in both the elite field and by ambitious exercisers who want the best equipment for their bike.

At Transition Zone we are specialists in triathlon and cycling equipment at the highest level. That's why we have chosen Cema as one of our preferred suppliers of ceramic bearings. We carry both bottom bracket bearings, pulley wheels and wheel bearings from Cema - all carefully selected for high performance and compatibility with modern bicycles.
