### **Pros and Cons of the SunRace FCR8700ASS2BX R80 Square Taper Triple Crankset (170mm BCD, 52/42/30T, 8-Speed, Touring)**

#### **Pros**

1. **Touring-Focused Design** The R80 model is specifically engineered for touring, featuring a sturdy 170mm BCD (Bottom Bracket Center) and reinforced components to handle long-distance riding, heavy loads, and rough terrain. This makes it well-suited for gravel, mixed surfaces, and loaded bikes.

2. **Square Taper Interface** The square taper spindle is a durable, time-tested standard that ensures a secure fit for the bottom bracket and chainrings. It is less prone to wobble or slippage compared to some modern hollowtech interfaces, which can be an advantage for touring where reliability is critical.

3. **8-Speed Compatibility** The crankset is designed for 8-speed drivetrains, which is a practical choice for touring. While modern 1x or 2x setups are popular, an 8-speed triple offers versatility for steep climbs and descending, which can be useful in varied terrain. It also works well with older or budget-friendly shifters and derailleurs.

4. **Durable Construction** SunRace is known for producing affordable yet robust components. The FCR8700 series typically features steel cranks with reinforced arms, which can handle the stresses of touring without excessive flex. The chainrings are often made from hardened steel for longevity.

5. **Wide Ratio Range** The 52/42/30T setup provides a broad gear range, allowing for efficient climbing (especially with the 30T small ring) and strong descending power. This is ideal for touring where you may encounter both steep hills and fast descents.

6. **Compatibility with Aftermarket Parts** The square taper design means you can easily replace the bottom bracket or chainrings with aftermarket parts if needed. This is useful for upgrading or repairing components over time.

7. **Cost-Effective** Compared to higher-end touring cranksets (e.g., Shimano Deore, SRAM NX, or carbon options), the SunRace FCR8700 is significantly cheaper. This makes it a practical choice for budget-conscious riders who still want a reliable touring setup.

8. **Easy Maintenance** Square taper cranks are straightforward to service. Chainrings can be replaced individually if worn, and the bottom bracket is accessible without specialized tools in many cases.

#### **Cons**

1. **Weight** Steel cranks are heavier than aluminum or carbon alternatives. While this isn t a major issue for touring (where weight isn t as critical as durability), it may feel noticeably heavier than a modern aluminum crankset (e.g., Shimano Deore or SRAM NX). For a 170mm BCD triple, you can expect the crankset to weigh around **1,200 1,400 grams**, which is on the heavier side.

2. **Limited Modern Compatibility** The 8-speed drivetrain is less common in modern bikes, which often use 9-, 10-, or 11-speed setups. This means you may need to source compatible shifters, derailleurs, and cassettes separately, which can be more expensive or harder to find. If you re building a new bike, you ll need to plan around this limitation.

3. **Chainline Issues** Some riders report that the chainline on SunRace triple cranks can be slightly off compared to Shimano or SRAM, leading to chain rub or poor shifting. This is more common with aftermarket chainrings but can also affect stock setups. A quick chainline check and adjustment may be necessary.

4. **Less Refined Shifting** While SunRace components are durable, they are not known for ultra-smooth shifting. If you prioritize precise, quiet shifting, you may find that higher-end brands (e.g., Shimano Deore, SRAM NX) offer better performance. However, for touring, smooth shifting isn t always the top priority.

5. **Build Quality Variability** Some users report inconsistencies in SunRace s build quality, such as uneven chainring teeth or slight imperfections in the crank arms. While this isn t universal, it s worth researching reviews to see if others have experienced similar issues.

6. **Square Taper Limitations** While square taper is durable, it requires regular maintenance to prevent wear and play. Over time, the spindle can develop a slight wobble, which may affect shifting or cause noise. Hollowtech (used in modern cranks) is generally smoother but requires more precise installation.

7. **Aesthetics** The FCR8700 series has a utilitarian, industrial look that may not appeal to riders who prefer sleek or modern designs. However, this is subjective and doesn t impact performance.

8. **Potential for Chainring Wear** The 30T small ring on a triple crankset can wear out faster than a larger ring due to higher stress. If you frequently ride in tight gears (e.g., steep climbs), you may need to replace the small ring more often than the middle or large ring.

---

### **Conclusion**

The **SunRace FCR8700ASS2BX R80 square taper triple crankset** is an excellent choice for **touring riders** who prioritize **durability, reliability, and affordability** over weight savings or ultra-smooth shifting. It excels in environments where a robust, low-maintenance drivetrain is needed such as gravel touring, loaded bikes, or mixed-terrain riding. The 170mm BCD and reinforced construction make it well-suited for heavy use, while the 52/42/30T setup provides a versatile gear range.

However, if you re building a **modern bike** or prefer **lighter weight, smoother shifting, or wider compatibility with 9/10/11-speed drivetrains**, you may want to consider alternatives like:

- **Shimano Deore M6100 (1x or 2x)** A more refined 8-speed option with better shifting.

- **SRAM NX (1x or 2x)** A durable, lightweight alternative with modern compatibility.

- **Shimano Deore HG50/HG60 (triple, 8-speed)** A slightly higher-end steel triple with better chainline precision.

- **Aluminum Touring Cranks (e.g., SunRace FCR8700ASS2BX in aluminum)** If weight is a concern, SunRace also offers aluminum versions of this crankset.

For **budget-conscious touring riders** who don t need the latest tech and want a **no-frills, heavy-duty crankset**, the SunRace FCR8700ASS2BX R80 is a **solid recommendation**. It balances cost, durability, and functionality well for its intended use.

If you re unsure, test-ride a bike with this crankset or consult reviews from touring cyclists who have used it long-term to gauge its suitability for your specific needs.
