Title: Cassette 12speed with good shifting performance
Post by: DP68SL8 on August 26, 2026, 12:07:36 AM

Any tips for a good light 12speed road cassette? Currently running the very light ZTTO 11-34 with a dura-ace di2 groupsets. Shifting in the smaller coggs is a bit rough, one gear barely shifts Up, an other barely down...
Considering switching to the wheeltop groupsets, but I'd like to stay with the light Dura Ace...

Swap out the chain. Any roughness on the ZTTO cassette is most likely due to the Shimano chain profile. A chain with a more neutral chain profile like a KMC X12 should shift much better on third party cassettes. Either that or just use Shimano cassettes with Shimano chains.
