Product Description

Split Second's Oversized Pulley Wheel System for Shimano Ultegra and Dura Ace 12 Speed

Split Second presents a revolutionary oversized pulley wheel system tailored for Shimano Ultegra and Dura Ace 12 speed. This system features a carbon frame, complemented by two oversized pulley wheels made of aluminum, with 14 and 17 teeth. This construction is designed to significantly improve the bike's performance.

Advanced ceramic bearings

The core of this system is the specially designed ceramic bearings, where both bearing rings and balls are made of ceramic material. These bearings ensure an extremely low rolling resistance, which is essential for optimal performance. The bearings are fully enclosed to minimize maintenance, a significant improvement over similar products from other brands.

Improved chain dynamics

The two oversized pulley wheels work together to reduce chain compression. This, together with the smooth ceramic bearings, significantly minimizes friction. The result is a potential energy saving of 4-5 watts compared to standard pulley wheel systems, which can be decisive for competitive purposes.

Lightweight design

Despite its robust construction and advanced technology, Split Second's Oversized Pulley Wheel System weighs only 72 grams. This lightweight design ensures that no undue weight is placed on the cyclist, making the system ideal for both training and competition.

Installation recommendations

For best results it is recommended to install this pulley wheel system together with a new chain. The larger pulley wheels often require a longer chain than standard configurations. Furthermore, the use of a maximum of a 34T cassette is recommended to ensure the most efficient gear change.

Compatibility Information

Important to note is that this system is designed specifically for Shimano 12 speed groupsets. For those who use Shimano 11 speed, a corresponding version is also offered in the shop. This ensures that cyclists with different Shimano configurations can benefit from Split Second's innovative technology.

Split Second – for those who love a clean and well-oiled bike

Whether you ride road, gravel or tri, one thing is certain: a well-maintained bike rides better, lasts longer and looks much cooler. Split Second offers a complete solution for those who do not compromise on maintenance. When you use products from Split Second to clean and care for your bike, it not only makes it easier to keep your bike looking good – it also improves your performance and reduces the risk of unnecessary wear. Dust, dirt and grime quickly stick after just one ride, and it can slow down both gear shifting, braking power and your overall riding pleasure. Here Split Second stands out as the obvious choice for riders who want both function and finish at the top.

Bicycle care with focus on detail

Split Second was developed with a clear goal: to make it easy and efficient to maintain your bike without compromising on quality. Their products cover the entire spectrum of bike care – from degreasing and cleaning the drivetrain to protecting the frame and moving parts. With regular use, you extend the life of your bike's components, keep the chain and cassette sparkling clean and ensure that everything works exactly as it should. When you wash your bike with dedicated cleaning products, you avoid damaging the surfaces and preserve the finish of carbon fiber, paint and metal. In addition, it provides a more efficient ride, because a clean drivetrain transfers more watts and reduces friction – and who doesn't want free speed?

Efficient maintenance all year round

Split Second is an obvious choice in all seasons – but especially in the Danish winter and shoulder seasons, where rain, salt and mud are a regular fixture, it is crucial to have good routines for cleaning and lubrication. It is not only about keeping the bike neat, but also about protecting investments in gears and components. By washing and maintaining your bike regularly with dedicated products, you avoid rust, ingrained dirt and unnecessary wear, which can otherwise quickly become expensive. A maintained bike requires fewer repairs, lasts longer and performs better – and with Split Second it becomes a simple and manageable task. In short: A good wash and lubrication after every 3-5 rides should be a regular ritual, and with the right equipment it only takes a few minutes.
