105 FC-R7000 Crankset - No Chainring

HOLLOWTECH II is a technology by Shimano that features hollow crank arms, making them lighter yet strong and stiff. This design enhances the efficiency of power transfer from your legs to the bike, allowing for more effective pedaling. If you're looking to improve your cycling performance, choosing a bike with HOLLOWTECH II can help you ride faster and with less effort.

The Q Factor is the distance between the pedals on a crankset. A wider Q Factor, like 146mm, can provide more stability and comfort, especially for riders with wider hips. However, it can also influence bike handling. If you prioritize comfort during long rides, a bike with an appropriate Q Factor for your body type can enhance your overall cycling experience.

The chainline refers to the distance from the bike's centerline to the middle of the chainring. A proper chainline, such as 43.5mm, ensures smooth shifting and reduces wear on the chain and gears. If you want to maintain your bike's efficiency and longevity, paying attention to the chainline when selecting components is crucial.

LINKGLIDE is Shimano's drivetrain technology designed for smoother and more reliable shifting, especially under load. This means that when you're climbing hills or accelerating, your shifts will be more precise and less likely to skip. If you want a bike that performs well in various conditions, opting for LINKGLIDE technology can significantly enhance your riding experience.

Pressfit and Threaded BB types refer to how the bottom bracket is installed in the bike frame. Threaded BBs screw into the frame, while Pressfit BBs are pressed in. Threaded BBs are generally easier to install and maintain, while Pressfit BBs can save weight. Your choice may depend on your preference for maintenance and the specific bike design you are considering.

Each of these technologies—HOLLOWTECH II, Q Factor, Chainline, LINKGLIDE, and BB types—plays a significant role in your bike's performance. They affect weight, comfort, shifting efficiency, and power transfer. Understanding these features can help you make an informed decision when purchasing a bike, ensuring you choose one that aligns with your riding style and goals.
