Shimano is known for creating parts that work perfectly together and can withstand many hours of intensive use, regardless of whether you ride road, gravel or triathlon.

Cassettes and chains – the key to a smooth and efficient transmission

A well-maintained cassette and chain are essential for an efficient and smooth cycling experience. Shimano has perfected these parts, and it's clear when you first try them. Their cassettes are known for their precise shifting and durability, and they're designed to work seamlessly with Shimano's own chains and rear derailleurs. Combined with a well-lubricated chain, you get a transmission that feels light, efficient and reliable - even under pressure. Whether you're riding with high watts or climbing long climbs, Shimano ensures that your gear changes are precise and without any wobble in the roller. This gives you more time to focus on your effort - and less time to fuss with equipment. That's why so many choose Shimano as their go-to supplier when it comes to the core function of their bike.

Bike parts you can trust – all the way around

In addition to chains and cassettes, Shimano offers a huge range of bike parts that together create a complete and well-balanced experience on the bike. From brakes and cranksets to front and rear derailleurs – all parts are developed with a focus on quality and compatibility. This means that you get a system where everything works together and where you rarely have to worry about unforeseen problems. When cycling or doing triathlons, it is crucial that the equipment works – both in training and on race day. Here Shimano is one of the most reliable solutions on the market. Their parts are thoroughly tested, intuitive to install and easy to maintain. If you combine this with the right set-up and regular care, you have a setup that will last for many seasons. Shimano is not just a brand – it is a seal of quality for those who take their cycling seriously.
