Review IZUMI Super Toughness 1/8 Inch Chain Links Used Njs Track Pista Keirin Japan

The **Izumi Toughness 1/8" Chain (Model 652710641938, 96 Links, NJS Track Pista/Keirin)** is a high-performance, precision-engineered bicycle chain designed specifically for competitive track cycling, including disciplines like pista (sprint) and keirin racing. Crafted from Izumi s proprietary **Toughness** series, this chain is built to withstand the extreme demands of high-speed, high-stress track racing, where reliability and durability are non-negotiable. The **1/8-inch width** is optimized for track-specific derailleurs and cassette setups, ensuring seamless engagement with the drivetrain while minimizing friction and wear critical factors in races where every fraction of a second counts. Constructed from **high-grade steel**, the chain features a **hardened roller design** that resists deformation under the intense forces generated during sprints and accelerations, maintaining consistent meshing with the chainrings and cogs. The **96-link length** is tailored for track bikes, which typically operate with a single-speed or fixed-gear setup, eliminating the need for shifting and reducing mechanical inefficiencies. The **NJS (Non-Jamming System)** technology further enhances performance by preventing chain derailment during aggressive pedaling, a common issue in track racing where riders push the limits of their bikes. Whether navigating tight turns on a velodrome or unleashing explosive power in a keirin race, this chain delivers **superior strength, smooth operation, and long-lasting durability**, making it an essential component for serious track cyclists who demand nothing less than peak performance.

**Pros and Cons of buying a Izumi 652710641938 Toughness 1/8" Chain (96 Links, NJS Track, Pista/Keirin)**

1. **Durability and Performance** The Izumi Toughness chain is designed for track cycling, where high stress and repeated tension are common. The 1/8" width is optimized for track frames and derailleurs, reducing the risk of stretching or breaking under heavy loads. The NJS (New Japanese Standard) compatibility ensures it fits modern track setups, including keirin and pista racing.

2. **Precision Engineering** Izumi chains are known for their tight tolerances and smooth operation, which is critical in track cycling where efficiency and reliability are paramount. The 96-link length is standard for many track bikes, making it a versatile choice for riders who may switch between different frame sizes or setups.

3. **Compatibility with Track-Specific Components** This chain is built for track use, meaning it works seamlessly with track-specific derailleurs (like Shimano or SRAM track models) and cassette systems. It avoids the potential mismatches that can occur with road or mountain bike chains on track frames.

4. **Longer Lifespan Compared to Road Chains** Track chains endure less wear from road debris (like gravel or mud) since they operate in a controlled environment. The Toughness series is reinforced to handle the repetitive stress of track racing, potentially lasting longer than a standard road chain under similar conditions.

5. **Brand Reputation** Izumi is a trusted name in cycling, particularly for track and time trial disciplines. Their chains are often preferred by professional and elite-level riders for their consistency and performance.

6. **Ease of Maintenance** The chain s design simplifies cleaning and lubrication, which is important in track racing where chains can accumulate dust and grime from the track surface. Proper maintenance extends its lifespan and ensures smooth shifting.

7. **Lightweight** Track chains are generally lighter than road chains of the same width, contributing to a more agile and responsive bike. The 1/8" width strikes a balance between strength and weight, making it suitable for high-speed disciplines like keirin.

1. **Limited Road Use** This chain is not designed for road cycling. Using it on a road bike could lead to premature wear due to the different stresses and debris encountered on paved surfaces. The chain s width and track-specific tolerances may also cause compatibility issues with road derailleurs or cassettes.

2. **Higher Cost** Track-specific chains like the Izumi Toughness are typically more expensive than standard road chains. While the price reflects the specialized engineering, it may not be cost-effective for riders who primarily use their bike for road cycling.

3. **Specialized Availability** Track chains are less commonly stocked in general bike shops compared to road chains. Purchasing may require ordering online or visiting specialty track bike shops, which could add to the inconvenience or shipping costs.

4. **Potential for Overkill for Casual Use** If you re not a serious track racer or only occasionally ride on the track, the durability and precision of this chain may be unnecessary. A high-quality road chain could suffice for most track sessions without the extra cost.

5. **Chain Wear Monitoring Required** Track chains can stretch more quickly than road chains due to the high tension and repetitive motion. Riders must regularly check chain wear (using a chain checker) and replace it before it becomes a safety hazard, especially in competitive settings.

6. **Limited Aftermarket Support** Unlike road chains, which have a wide range of replacement parts and accessories, track chains may have fewer aftermarket options. This could be a drawback if you need specific tools or replacements down the line.

7. **Not Universal for All Track Setups** While the 96-link length is common, some track bikes or custom setups may require different chain lengths. Double-checking compatibility with your specific frame and derailleur setup is essential to avoid issues.

The Izumi 652710641938 Toughness 1/8" chain is an excellent choice for track cyclists, particularly those engaged in pista or keirin racing, where reliability, durability, and precision are critical. Its specialized design reduces the risk of failure under the high stresses of track cycling and ensures smooth operation with track-specific components. However, it is not suitable for road use and may be overkill for casual or infrequent track riders. The higher cost and limited availability also make it a niche purchase.

If you are a dedicated track racer or plan to compete in disciplines like keirin or pista, this chain is a worthwhile investment. For riders who occasionally use their bike on the track or those on a budget, a high-quality road chain (with proper maintenance) might be a more practical alternative.

- **Buy it if:** You are a serious track racer (keirin, pista, or criteriums on track frames), prioritize durability and performance, and have a track-specific setup. The chain s longevity and compatibility with track components justify the cost.

- **Avoid it if:** You primarily ride on the road, are a casual track rider, or want a more budget-friendly option. In such cases, a standard road chain (e.g., Shimano DN-S500 or SRAM PowerLink) would be more versatile and cost-effective.

- **Consider alternatives:** If you re unsure about the chain s fit or need a backup, purchase a slightly longer chain (e.g., 100 links) to allow for adjustments or future use. Also, ensure your track derailleur and cassette are compatible with the NJS standard.
