e*thirteen Cassette Replacement Clusters & Parts

Only replace the cogs you've actually worn out

Unlike most one-piece cassettes, e*thirteen Helix and TRS cassettes come apart into a steel section and an aluminium section. Replace just the worn part and keep riding for a fraction of the cost of a new cassette.

Also here: the XDR spacer, Hope XD shim kit and the small bolts, bushings and lock screws that hold it all together.

The Inside Line:
Your small cogs wear out first because you spend all day mashing the fast gears. We won't judge, just help you replace the bit you killed.

Features:

Helix Race steel and aluminium clusters for 9-50, 9-52 and 13-52
Helix Race Gravel 9-32T steel section
TRS Plus and TRS Race 11/12-speed cog sets
LG1 7-speed DH cassette
XDR spacer, Hope shim kit, bushing, lock screw and bolts

Fits:

Helix 12-speed cassettes and older e*thirteen TRS cassettes. Check the cassette range each part is listed for.

Tip:

Check your chain when you replace a cluster. A chain worn past 0.5% will chew through new cogs fast.
