Part of Shimano s Ultegra lineup, this derailleur embodies the brand s commitment to innovation and durability, making it an ideal choice for both road cyclists and gravel enthusiasts who demand consistency across rough terrain or demanding climbs.

Its **low-profile design** reduces interference with wide tires, making it particularly well-suited for gravel and adventure bikes where tire clearance is a priority. The **pivot point alignment** is meticulously tuned to minimize friction, allowing for quicker, more responsive shifts that reduce chain noise and extend the lifespan of the drivetrain. Shimano s **Ultegra-grade bearings** ensure smooth operation, even under heavy loads, while the **durable spring tension system** maintains consistent shifting performance over time. Whether navigating tight corners, climbing steep gradients, or cruising on smooth pavement, this derailleur delivers the precision and reliability expected from Shimano s premium lineup.

For riders who prioritize performance without sacrificing durability, the **RD-6700-SS Ultegra Cage Rear Derailleur** represents an excellent balance of technology and practicality. Its compatibility with Shimano s broader Ultegra and Dura-Ace systems ensures seamless integration into existing setups, while its robust construction and refined engineering make it a dependable choice for those who demand nothing less than excellence from their cycling components. Whether paired with a mechanical or electronic shifting system, this derailleur is engineered to elevate the riding experience, offering effortless shifts, reduced maintenance, and the confidence of knowing that every gear change is precise and reliable.

### **Shimano RD-R6700 (Ultegra Cage) Rear Derailleur: Pros and Cons**

1. **Performance-Oriented Design** The Ultegra cage is engineered for better shifting precision and reduced chain slap compared to lower-tier models. It features a more rigid cage structure, which improves shifting consistency, especially under heavy loads or in rough terrain.

2. **Compatibility with Modern Groupsets** The RD-R6700 is designed to work seamlessly with Shimano s 105 and Ultegra groupsets, including the latest 12-speed drivetrains. It is also compatible with some SRAM and Campagnolo components, though some aftermarket parts may require adjustments.

3. **Durability and Reliability** Shimano s mid-to-high-end derailleurs are known for their robustness. The R6700 is built to last, with a sturdy frame and reliable shifting performance over time, especially when paired with a well-maintained drivetrain.

4. **Better Chain Engagement** The cage design helps keep the chain more aligned with the sprockets, reducing the risk of derailments, particularly on smaller cogs. This is beneficial for climbers and riders who frequently shift to the rear cassette.

5. **Lightweight Construction** While not as light as carbon components, the R6700 is still relatively lightweight for its class, making it a good option for riders who prioritize performance without excessive weight.

6. **Aftermarket Support** Shimano s Ultegra components have a strong aftermarket presence, meaning you ll find replacement parts, upgrades (like carbon cages), and tuning services more easily than with some other brands.

7. **Cost-Effective Upgrade** For riders already using a 105 or Ultegra groupset, upgrading to an R6700 cage can be a cost-effective way to improve shifting performance without a full groupset overhaul.

---

1. **Higher Cost Than Entry-Level Options** The R6700 is more expensive than Shimano s Deore or SLX derailleurs, making it less accessible for budget-conscious riders. If you re already using a high-end groupset, the upgrade may not feel as justified.

2. **Overkill for Casual or Lightweight Use** If you ride mostly on smooth roads or don t frequently shift to the smallest cogs, the performance gains of the Ultegra cage may not be noticeable enough to warrant the extra cost.

3. **Limited Weight Savings Compared to Carbon** While the R6700 is lighter than its Deore counterpart, it is still heavier than aftermarket carbon cages (e.g., from Race Face or SRAM). If weight is a critical factor, a carbon upgrade might be preferable.

4. **Potential for Chain Slap on Rough Terrain** While the cage design reduces chain slap compared to lower-tier models, it is not entirely eliminated. On very rough terrain or with a poorly aligned drivetrain, some chain slap can still occur.

5. **Compatibility Issues with Non-Shimano Components** While the R6700 works with many Shimano parts, pairing it with non-Shimano components (e.g., SRAM cranks or Campagnolo shifters) may require adjustments or compatibility concerns, such as different shift lever indexing.

6. **Maintenance Sensitivity** Like all high-performance derailleurs, the R6700 benefits from regular maintenance. Neglecting cleaning, lubrication, and alignment can lead to shifting issues, making it less forgiving than more durable but lower-end options.

7. **No Major Advantage Over 105 in Pure Performance** If you re already using a 105 groupset, the R6700 s performance gains over a 105 derailleur may be marginal unless you specifically need the Ultegra cage s characteristics (e.g., for a mixed Shimano/SRAM build).

---

The **Shimano RD-R6700 (Ultegra Cage) rear derailleur** is a strong mid-range option that excels in shifting precision, durability, and compatibility with high-end Shimano groupsets. It is particularly well-suited for riders who prioritize smooth, reliable shifting such as climbers, time trialists, or those using mixed drivetrains and who are already invested in Shimano s ecosystem. However, its higher cost and limited weight savings compared to carbon alternatives may not justify the upgrade for casual riders or those on a tight budget.

If your primary goal is **maximizing shifting performance within Shimano s lineup** and you re already using a 105 or Ultegra groupset, the R6700 is a worthwhile upgrade. For **budget-conscious riders** or those who prioritize weight savings, a Deore or SLX derailleur may suffice. If you re open to aftermarket options, a **carbon cage** could offer better performance per pound spent.

- You re using a 105 or Ultegra groupset and want smoother, more precise shifting.

- You frequently shift to the smallest cogs or ride in conditions where chain alignment is critical.

- You value Shimano s ecosystem and compatibility with other high-end Shimano parts.

- You re willing to pay a premium for improved performance over lower-tier derailleurs.

- You re on a tight budget and a Deore or SLX derailleur meets your needs.

- You prioritize weight savings over shifting performance and are open to aftermarket carbon cages.

- You ride mostly on smooth roads and don t frequently use the smallest cogs.

- You re building a mixed-brand drivetrain and compatibility concerns arise.

For most riders already in the Shimano Ultegra or 105 ecosystem, the R6700 is a **solid, high-quality choice** that delivers noticeable improvements over lower-tier models. However, weigh the cost against your specific riding needs before committing.
