Replacement aluminium top cluster for e*thirteen's Helix Race 12-speed 13-52T cassette – the two largest cogs, sold separately so you can replace just the worn part rather than the whole cassette.

Black anodised aluminium, 45-52T.

Compatibility & fit

This is not a complete cassette – it's the aluminium cluster only, and fits the Helix Race 12-speed 13-52T cassette exclusively; it isn't interchangeable with the other Helix Race cassette range. The steel lower cluster on the same cassette is also sold separately. The Tune workshop can fit this as part of a drivetrain service.

e*thirteen's Infinite Ride Warranty covers this part for 10 years against manufacturing and material defects; normal wear on wear parts such as pawls, springs and cogs isn't covered. For warranty support, return the product to Tune Cycles and we'll manage the claim with e*thirteen's Australian distributor. This is in addition to your rights under the Australian Consumer Law, so keep your proof of purchase.
