Shimano Ultegra CS-R8101 12s 11-34T cassette: the ultimate derailleur for your road bike

If you are looking for a road cassette that offers you maximum performance, the Shimano Ultegra CS-R8101 12s 11-34T Cassette is the ideal option for you. This cassette is part of the new Ultegra R8100 groupset, which is characterized by its innovative design and advanced technology, inspired by the professional range Dura-Ace groupset.

HYPERGLIDE+ technology: the secret to fluid and precise shifting

The Shimano Ultegra CS-R8101 12s 11-34T Cassette features HYPERGLIDE+ technology, which consists of a special design of the sprocket teeth, which makes it easier to engage and disengage the chain during shifting. In this way, a faster and smoother shift is achieved, both in the ascending and descending directions, regardless of the force or cadence applied to the pedals.

This technology, which has already been successfully tested in Shimano's mountain groups, represents a revolution in road cycling, as it allows you to change gears in any situation, without having to reduce speed or intensity. This way, you can make the most of your potential and enjoy a unique driving experience.

Compatibility with 11 and 12 speed rear hub bodies

Another advantage of the Shimano Ultegra CS-R8101 12s 11-34T Cassette is its compatibility with Shimano's 11- and 12-speed rear hub bodies. This means that you will be able to install this cassette on your bike without having to change the hub or rear wheel, saving you time and money.

Additionally, this cassette has an optimized design to reduce weight and improve rigidity, resulting in greater efficiency and durability. The sprockets are made of steel, with two aluminum spiders that hold them and distribute the weight. The smallest pinion has a larger diameter than previous models, which improves the stability and balance of the assembly.

Combination of sprockets from 11 to 34 teeth: versatility and adaptability

The Shimano Ultegra CS-R8101 12s 11-34T Cassette has a combination of sprockets from 11 to 34 teeth, offering a wide range of ratios to adapt to all types of profiles and riding styles. With this cassette you will be able to face the most demanding climbs with ease, thanks to the larger sprockets that will provide you with a lower ratio. You will also be able to maximize your speed on the flats or descents, with the smaller sprockets that will give you a higher ratio.

Furthermore, the progression between the sprockets is carefully studied so that the jump between gears is as minimal as possible, thus avoiding sudden changes or loss of rhythm. This way, you can maintain a constant and comfortable cadence, without sacrificing power or precision.
