The fixie drivetrain (fixed gear) is both simple and efficient. Unlike traditional multi-speed bikes, it relies on a stripped-down system for a direct connection between the rider and the road. Here is a detailed guide to better understand the components, specificities and advantages of this type of transmission for fixie bike.
1. The components of the fixie drivetrain :
Sprocket
Fixed :
- Direct attachment to the wheel, which turns the pedals as soon as the wheel is in motion.
- Typical size: between 14 and 18 teeth, directly influencing pedaling cadence.
- Generally fixed with a threading system and a lockring (counter-nut) to prevent unscrewing when backpedaling.
Flip Flop:
- Hub with two sides: one for the fixed gear, the other for a freewheel.
- Allows you to quickly switch from fixed mode to freewheeling mode for more versatility.
Chain
Kind :
- 1/8" chain (standard width for single speed transmissions).
- Wear-resistant, often made of sturdy steel with a rust-proof finish.
- Some chains are colored to add an aesthetic touch.
Chainring :
Features :
Typically 44 to 52 teeth for a good balance between speed and cadence.
Simple design, often with narrow teeth for better chain compatibility.
Materials: aluminum for lightness or steel for durability.
Cranks
Length :
Standard: between 165 mm and 175 mm, depending on the size of the cyclist and the type of use.
Materials:
Aluminum: light and rigid.
Steel: more durable, often used for retro models.
2. Operation of the fixie drivetrain :
Direct connection:
With a fixed gear, the movement of the pedals is directly linked to that of the rear wheel.
The cyclist controls the speed by pedaling more or less quickly and can even brake by backpedaling.
No inertia:
Unlike freewheel bikes, it is not possible to stop pedaling without the wheel stopping spinning.
Mechanical simplicity:
Fewer moving parts compared to geared transmission systems, reducing maintenance and risk of malfunction.
3. Advantages of fixie drivetrain :
Efficiency :
Direct transmission, without loss of energy due to derailleur or freewheel systems.
Simplicity:
Fewer components means less weight and less maintenance required.
Sustainability :
Robust components designed to last even under intensive use.
Versatility:
Flip-flop hub allowing you to choose between a fixed gear or a freewheel.
Style :
Clean appearance, which fits perfectly with the minimalist aesthetic of fixies.
4. Maintenance and Adjustments :
Chain tension:
The chain should be taut, but not too tight, to avoid premature wear or chain skipping.
Checking the sprocket and lockring:
Check regularly that the lockring is tight to prevent it from coming loose while backpedaling.
Lubrication:
Regular lubrication of the chain and chainring/sprocket teeth is essential for smooth operation.
Wear :
Inspect the sprocket and chainring teeth regularly for irregular wear.
5. Fixie drivetrain configurations and ratios:
The choice of the ratio between the chainring and the pinion is crucial to adapt the transmission to your use.
Common ratio:
2.5:1 (for example, a 48-tooth chainring and an 18-tooth sprocket).Suitable for urban use, balancing speed and ease on hills.
Ratio for speed:
Larger, like 3:1 (52 teeth for the chainring and 17 teeth for the sprocket).Ideal for quick commutes or errands.
Ratio for comfort:
Smaller, like 2:1 (44 teeth for the chainring and 22 teeth for the sprocket).Facilitates starts and climbs, at the expense of maximum speed.
6. Popular Brands:
Chains:
KMC: Robust, durable, often available in various colors.Izumi: High-end, often used by track cyclists.
Sprockets:
Miche: Italian quality, with machined steel sprockets.BLB: Affordable and aesthetically pleasing options for fixie enthusiasts.
Chainrings and cranksets:
Sugino: Renowned for its quality and longevity.SRAM: Lightweight and reliable option for modern fixies.
Hubs:
Phil Wood: High-end hub, known for its durability.Novatec: Versatile and economical flip-flop.
7. Uses and Styles
Urban use:
Balanced transmission ratio for navigating the city.Durable components for everyday commuting.
Track racing:
Rigid transmission and high ratio for maximum speed.Lightweight components to reduce overall weight.
Hobbies :
More comfortable ratio for relaxed rides.Emphasis on style and personalization.
Conclusion
The fixie drivetrain embodies the very essence of this type of bike: simplicity, efficiency and style. With carefully chosen components, it offers a unique experience, where every pedal stroke is directly felt on the road. Whether for daily or sporting use, the options available allow you to personalize your fixie according to your needs and preferences.
