Jagwire Sport 4mm Mini Inline Cable Tension Adjusters Pair

The Jagwire Sport 4mm Mini Inline Cable Tension Adjusters let you dial in derailleur indexing on the fly — no tools, no barrel adjuster at the lever or derailleur required. Thread them inline on your cable housing anywhere along the run, and you have a convenient tuning point exactly where you need it.

Compact enough to sit neatly along the frame, these adjusters are a practical addition to any cable-actuated drivetrain, particularly on bikes where the stock barrel adjusters are hard to reach or absent altogether. Sold as a pair.

• Compatible with 4mm derailleur cable housing
• Inline installation — no lever or derailleur modification needed
• Sold as a pair
