Chainless Change: Reliable Bicycle Drivetrains for the Cyclist
Introduction to Reliable Drivetrains
As a seasoned cyclist, one of the most common concerns is the reliability of the bicycle drivetrain. Challenges like chain drops and mechanical failures can be frustrating and even dangerous. However, there are solutions designed to minimize these issues. This article explores some of the most reliable drivetrains and maintenance tips to help cyclists enjoy a smoother and more enjoyable ride.
Shimano 8-speed Internal Gearing Hub: A Sturdy Choice
The Shimano 8-speed internal geared rear hub is a superb choice for cyclists seeking reliability and minimal maintenance. While it may not be as light as other options or offer the widest range of gears, it excels in terms of durability and user satisfaction. Once installed properly, it offers an extremely reliable and trouble-free experience. Chain wear becomes less of an issue, and the odds of dropping the chain are significantly reduced, especially with the right crankset and chain guide.
Many of my friends with electronic shifters vouch for their responsiveness, but it's worth noting that even the most advanced systems can occasionally misfire, particularly if not used correctly. For instance, if you are in the smallest chainring and on the smallest cassette while shifting to the big cog, you might still experience a failure.
Understanding the Limitations of Bicycle Mechanics
No machine, mechanical or otherwise, is created to be completely indestructible. The notion of a machine that will never break is a non-starter, especially in the realm of bicycles, which are typically engineered to be lightweight and compact. Despite this, the gears are often among the most reliable components on a bicycle. Many cyclists have had positive experiences with derailleurs, with some reporting that they perform much better than others.
Common Reliability Issues and Solutions
While gears are generally robust, other parts, such as bearings, can often be the source of failure. Proper maintenance and setup are crucial to ensuring that your drivetrain runs smoothly.
Adjustment Tips for Optimal Performance
Adjust Limit Screws: Properly set limit screws prevent the chain from accidentally falling off and potentially damaging the spokes. This is particularly essential when shifting onto the largest sprocket.
Adjust Tension Screw: Ensure that the upper jockey pulley does not touch or interfere with the largest sprocket when the chain is on it. At the same time, the pulley should not be too far from the cogs.
Lubrication: Use a drop of thick oil-based lubricant on the rollers, which can last up to a month in dry conditions, reducing friction and wear. Apply plenty of protection inside the rollers and avoid excess oil, which can attract dirt.
Chain Replacement: Replace your chain when it becomes 1/16" to 1/8" elongated. Proper chain length adjustment is also crucial. Ensure that it's possible to shift onto the largest sprocket from the largest chainring.
Front Derailleur Positioning: The front derailleur should be positioned so that the lower plate is parallel to the chainrings and positioned close enough to shift under all conditions without rubbing.
Cable Maintenance: Keep the cables clean and well lubricated to ensure smooth shifting.
Conclusion
While no drivetrain is perfect, reliable components and regular maintenance can significantly reduce the likelihood of chain drops and mechanical failures. The Shimano 8-speed internal geared rear hub, with proper setup and care, offers a dependable and nearly maintenance-free experience. By being mindful of these adjustments and maintenance tips, cyclists can enjoy a smoother, more efficient ride, even on challenging terrain.
