Shimano ’ Y6Z298012 cable end caps are essential finishing caps for ensuring the protection and longevity of derailleur cables. Designed for Shimano ’s SIS-SP40 and SP41 systems, they allow the ends of the cables to be neatly sealed whilst preventing water, dust and mud from entering the gear cable.

Thanks to their integrated seal, these end caps improve the watertightness of the cable system and help to maintain smoother, more consistent gear changes over time. They are particularly useful for mountain bikes, gravel bikes and road bikes, where weather conditions and flying debris can accelerate cable housing wear.

This pack of 200 pieces is ideal for workshops, mechanics or cyclists who maintain several bikes, ensuring a long-lasting supply for numerous repairs.
