S-PARTS Titanium Splined Crank Screws for SHIMANO Series
Splined crank bolts, like the S-PARTS titanium alloy ones compatible with Shimano series, are specialized components used to attach the crank arms to the bottom bracket spindle in bicycle drivetrains.
Key Differences Between Splined Crank Bolts and Regular Crank Bolts
-
Design:
- Splined Crank Bolts: These bolts have a splined interface, which means they are designed to fit into a crankset that has matching splines. This design provides a secure, precise connection that helps distribute pedaling forces more evenly.
- Regular Crank Bolts: Typically, these bolts might have a square taper or other non-splined designs, which might not provide as tight or precise a fit as splined interfaces.
-
Compatibility:
- Splined Crank Bolts: Specifically designed for cranksets with splined interfaces, like many Shimano cranksets. This includes systems like Shimano's Hollowtech II or other similar splined systems.
- Regular Crank Bolts: These are more generic and might fit a variety of non-splined cranksets, depending on their design.
Specific Use Cases
-
Shimano Series Compatibility: The S-PARTS titanium alloy splined crank bolts are compatible with Shimano cranksets that use a splined interface. This includes many of Shimano's high-end road and mountain bike cranksets.
-
Model Use: These bolts are used in cranksets such as Shimano's Hollowtech II system, which is common in many of their Deore, SLX, XT, XTR, 105, Ultegra, and Dura-Ace series.
Advantages of Using Titanium Alloy Splined Crank Bolts
- Weight: Titanium is significantly lighter than steel, which helps in reducing the overall weight of the bike.
- Strength and Durability: Titanium bolts are known for their high strength-to-weight ratio and corrosion resistance, making them a durable choice for demanding cycling conditions.
- Aesthetic Appeal: Titanium bolts often have a sleek appearance, adding a premium look to the bike.
In summary, splined crank bolts like the S-PARTS titanium alloy ones are specifically designed for use with splined cranksets, offering a secure and durable connection ideal for high-performance cycling setups, particularly those using Shimano components.
