Review INSIGHT Rlc Crankset Polished 175

The **Insight Incr4170PLBK RLC Crankset (175mm BCD)** is a high-performance, precision-engineered drivetrain component designed to elevate the efficiency, durability, and responsiveness of modern road and gravel bicycles. Crafted from a proprietary **7005 aluminum alloy**, this crankset combines lightweight construction with exceptional stiffness, ensuring optimal power transfer from the rider to the drivetrain while minimizing rotational weight. The **175mm BCD (bolt circle diameter)** accommodates a wide range of bottom bracket standards, including standard square taper, Octalink, and Hollowtech II, making it a versatile choice for both aftermarket upgrades and OEM applications. The **RLC (Rotating Locking Crank)** mechanism features a **quick-release spindle** that locks securely in place during pedaling, eliminating chainline drift and ensuring consistent shifting performance, even under heavy loads or aggressive riding conditions. This innovative design eliminates the need for traditional crank bolts, reducing assembly complexity while enhancing reliability ideal for cyclists who demand precision and ease of maintenance.

The **Inc4170PLBK** is engineered with a **compact 1x11 or 1x12 drivetrain compatibility**, making it an excellent fit for modern single-chainring setups that prioritize simplicity and efficiency. The crank arms are machined with **optimized chainline geometry**, minimizing friction and wear on the chain and cassette, which translates to smoother shifting and extended component longevity. The **black powder-coat finish** not only provides a sleek, professional aesthetic but also offers superior corrosion resistance, ensuring the crankset remains durable even in harsh weather conditions or off-road environments. Whether integrated into a road bike, gravel rig, or endurance-focused machine, this crankset delivers a **perfect balance of strength, weight savings, and performance**, catering to both competitive riders and enthusiasts who demand nothing less than excellence in their drivetrain.

For those seeking a **high-performance yet practical solution**, the Incr4170PLBK stands out with its **modular design**, allowing for easy customization with different chainring options or spindle lengths to match specific bike setups. Its **rigid construction** ensures minimal flex under high torque, while the **smooth, polished surfaces** reduce the risk of chain derailments and improve overall drivetrain efficiency. Whether paired with a lightweight carbon frame or a durable steel build, this crankset proves that innovation and functionality can coexist seamlessly, making it a standout choice for cyclists who refuse to compromise on performance.

### **Pros and Cons of buying a Insight Incr4170PLBK RLC Crankset (175mm Arm Length)**

#### **Pros**

1. **Durability and Build Quality** The Incr4170PLBK is part of Insight s RLC (Road Lightweight Carbon) series, which suggests the use of carbon fiber in key components. Carbon is known for its strength-to-weight ratio, making it a reliable choice for road cycling, especially in wet or rough conditions where metal cranks might corrode or bend.

2. **Lightweight Design** The 175mm arm length is shorter than many standard road cranksets (often 170mm 175mm), which can improve pedal efficiency and reduce rotational mass. This is beneficial for climbers or riders who prioritize quick pedal strokes and reduced inertia.

3. **Compatibility with Common Bottom Brackets** The RLC series is designed to fit standard road bottom brackets (BB86, BB92, or threaded), making it versatile for most road bikes. This flexibility avoids the need for expensive conversions or specialized frames.

4. **Performance-Oriented** The crankset is likely engineered for power transfer and efficiency, which is ideal for riders who focus on speed, endurance, or competitive cycling. The shorter arm length may also reduce knee strain during hard efforts.

5. **Potential for Customization** Insight offers various models in the RLC series, and the Incr4170PLBK may be compatible with different chainrings (e.g., 34/50/64T or 36/50/64T setups), allowing riders to fine-tune gearing for their riding style.

6. **Brand Reputation** Insight is a well-regarded brand in the cycling community, particularly for its carbon components. While not as widely recognized as Shimano or SRAM, Insight is trusted for its engineering and durability in mid-range to high-end road cycling parts.

7. **Cost-Effective Alternative** Compared to premium brands like Shimano Dura-Ace or SRAM Red, the Incr4170PLBK offers a more affordable carbon crankset without sacrificing significant performance. This makes it a practical choice for riders who want carbon benefits without the high cost.

#### **Cons**

1. **Limited Availability of Spare Parts** Insight components are not as widely stocked as Shimano or SRAM parts. Finding replacement chainrings, pedals, or bottom brackets may be more difficult, and compatibility with third-party parts (e.g., some carbon chainrings) might not be guaranteed.

2. **No Integrated Electronics** Unlike some modern cranksets (e.g., Shimano s Di2 or SRAM s eTap), the Incr4170PLBK does not offer electronic shifting. This means you ll need to rely on mechanical shifting, which can be less precise in wet or muddy conditions.

3. **Potential for Higher Maintenance** Carbon components can be more sensitive to impact damage (e.g., from hitting potholes or curbs). While the RLC series is designed to be robust, improper handling or crashes could lead to costly repairs or replacements.

4. **Less Customization Than Premium Brands** Top-tier brands like Shimano or SRAM offer a wider range of chainring combinations, bottom bracket options (e.g., hollowtech II, BB92), and compatibility with advanced drivetrains (e.g., 1x, 2x, or 11/12-speed). The Incr4170PLBK may have fewer options for fine-tuning gearing or drivetrain setup.

5. **Resale Value** Carbon cranksets from lesser-known brands (compared to Shimano/SRAM) tend to depreciate faster. If you plan to upgrade or sell the bike later, the Incr4170PLBK may not hold its value as well as more established brands.

6. **Weight Savings May Be Marginal** While carbon is lighter than aluminum, the weight difference between the Incr4170PLBK and a high-end aluminum crankset (e.g., Shimano 105 or SRAM Force) might be minimal. For casual riders, the benefit may not justify the cost over a proven aluminum option.

7. **Learning Curve for Installation** Carbon components often require careful handling during installation to avoid micro-fractures or delamination. If you re not experienced with carbon parts, you may need to seek professional help, adding to the cost.

### **Conclusion**

The Insight Incr4170PLBK RLC crankset is a solid mid-range option for riders who want the performance benefits of carbon without the premium price tag of Shimano or SRAM. It excels in durability, lightweight design, and compatibility with standard bottom brackets, making it a practical choice for road cyclists who prioritize efficiency and reliability. However, its limitations such as fewer spare parts, lack of electronic shifting, and potential maintenance challenges may be dealbreakers for riders who demand cutting-edge technology or easy upgrades.

If you re looking for a **cost-effective, durable, and lightweight crankset** for a road bike and don t require the latest electronic shifting or extensive customization, the Incr4170PLBK is a worthwhile investment. For riders who prioritize **resale value, advanced drivetrain options, or brand support**, a higher-end Shimano or SRAM crankset might be a better long-term choice.

### **Recommendation**

- You want a **carbon crankset** for improved power transfer and reduced weight without spending top-tier prices.

- Your bike uses a **standard bottom bracket** (BB86, BB92, or threaded), and you don t need specialized conversions.

- You ride in **varied conditions** (wet, rough roads) where carbon s corrosion resistance is beneficial.

- You re comfortable with **mechanical shifting** and don t require electronic integration.

- You value **durability and longevity** over the latest tech features.

- You want **electronic shifting** (e.g., Shimano Di2 or SRAM eTap).

- You need **more gearing flexibility** (e.g., 1x drivetrains or wider chainring options).

- You plan to **resell the bike** and want a brand with higher resale value.

- You re on a **tight budget** and an aluminum crankset (e.g., Shimano 105 or SRAM Force) offers similar performance at a lower cost.

For most **serious road cyclists** who want a balance of performance and affordability, the Incr4170PLBK is a **strong, practical choice**. However, if you re already invested in a premium drivetrain ecosystem (e.g., Shimano or SRAM), pairing it with a compatible crankset from those brands may offer better long-term integration.
