Running a Specialized Turbo Levo Comp eMTB. It has done 1300km from new over Sussex countryside, wet and dry, but has been well cared for and maintained. Has SRAM GX Eagle 11 speed cassette.
Have been watching chain stretch with my Park Tool measurer and my KMC e11 chain is now showing .50 stretch, so decided to change chain as a plan to prolong use of my cassette, according to widely discussed advice. Cassette costs £68, so seems worth trying to get more distance out of it by changing chains to lower cassette wear. Swapped chain with new identical chain. Now getting slippage on the lower few cogs when significant power applied. No slippage on bigger, less frequently used cogs, even with plenty of power applied. No slippage on smaller cogs when just applying moderate power. Problem is more apparent when starting off from standing starts, such as traffic lights.
The implication is that the smaller cogs are past their sell-by date and I need to replace my cassette.
I appreciate that it is commonly discussed that we should change cassette and chain together, but I was hoping by changing the chain earlier (at 0.50 stretch), I would get more miles out of the cassette (which is fairly pricey).
I think I'll probably put the old chain back on and run it with the old cassette until they mutually start causing problems.
Is the idea of changing my chain when stretch shows 0.50 just plain wrong?
Any opinions/advice/ideas would be appreciated, as changing chain and cassette is over £100 and I was hoping to maybe get 3 chains before a cassette change?
