SRAM Rival 1x: Hestitant shifting in middle of cassette when going to larger cogs - causes?
I have tried replacing the few months old cassette with a brand new identical cassette. While the shifting still isn't 100% perfect it has noticeably improved with no specific problem cogs anymore.
Update: I installed the original SRAM PG-1130 cassette (11-32) and a new PC-1130 chain (replacing a PC-1110 chain) sized around largest cog and the chainring bypassing the rear mech - plus three extra inner links and three extra outer links and the power lock link.
Now the shifting was crisp and flawless across the entire cassette. However, I was missing the crucial, &quot;sweat spot&quot; 16T cog.
So, with the same chain and length, I swapped the cassette back to the 11-28T (also PG-1130 series).
And the shifting remains flawless!
I think the main issue has been too short a chain all along - although I initially followed the official advice from SRAM with two extra inner links and two extra outer links for a 1x setup (They need to update those recommendations...)
