Index Rear Derailleurs
Product ID: SR-525, SR-525N
- Slant-parallelogram design adapts well to index shifting.
- EDB-plated steel.
- Short-cage model(525 has bracket).
- Weight: 265/284 grams.
- At every level, SunRce rear derailleurs offer reliable shifting performance and good durability.
- SunRace rear derailleurs fit every kind of drivetrain, from 24-speed index or friction to simpler 10-speeds and 3-speed cruisers.
- New springs on certain models upgrade compatibility with twist shifters.
- Upper-end models(SR-590 series) feature sleek redesigned cages, new pulley bolts, and sealed pulleys. These high-quality derailleurs are compatible with 24- and 21-speed index drivetrains.
- All SunRace rear derailleurs have durable, wear-resistant finishes. Upper-end models use patented surface finishes for extra protection against scratches.
- Upper-end models use a "B-tension" alignment adjuster. A simple screw aligns the derailleur's parallelogram and jockey wheel with the chainstay, an essential adjustment that improves shifting. The "B-tension" screw does not contact the dropout, relieving stress on the frame.
