{"title":"104 BCD gears","description":"\u003cp\u003e104 BCD chainrings are one of the most common chainring mounting systems for mountain and gravel bikes. They offer a good combination of stiffness and versatility for different cranksets, especially in 1x and 2x setups. 104 BCD chainrings allow for a wide range of tooth counts, the use of narrow-wide profiles, and effective chain retention in challenging off-road conditions. We offer both round and oval chainring profiles, in aluminum or carbon fiber, so you can find the option that is just right for your bike. When choosing a 104 BCD chainring, it is important to check compatibility with the crankset: the mounting standard, chain width, and drivetrain type affect functionality. A correctly chosen 104 BCD chainring improves pedaling efficiency, reduces chain wear, and ensures a long-lasting, quiet drivetrain. Our sales team will help you find the chainrings that are best suited for off-road, gravel riding, or e-bike use.\u003c\/p\u003e","products":[{"product_id":"ethirteen-turbocharger-race-espec-104bcd-spierbashguardchainring-34t","title":"e*thirteen Turbocharger Race e*spec 104BCD Bashguard\/Chainring 34T","description":"\u003ch3\u003ee\u003cem\u003ethirteen Turbocharger Race e\u003c\/em\u003espec 34T – protective spider, bashguard, and chainring package for e-MTBs\u003c\/h3\u003e\n\u003cp\u003eThe e\u003cem\u003ethirteen Turbocharger Race e\u003c\/em\u003espec 104BCD Spider \/ Bashguard \/ Chainring 34T is an integrated drivetrain protection and chainring solution for e-MTBs equipped with compact motor systems.
