Caja de cambio Shimano SP41

Shimano SP41 Derailleur Housing is Shimano's standard mechanical cable housing for rear derailleurs — built to work seamlessly with Shimano's own cable systems and compatible with most modern mechanical groupsets. The SP41 uses a compressed polymer liner to reduce friction and keep shifting feeling crisp over time, while the outer housing is designed to resist compression under cable tension. Available in Black, Grey, and White, so it can be matched to your build without compromise.

Sold by the metre, this is the housing to reach for when servicing a drivetrain or completing a fresh cable build — reliable, consistent, and straight from the source.
