SLX cassette toast at .5 chain stretch.

My chain just got to .5 On my Park go no go checker. I’ve been watching in closely for the last month or so. I put a new chain and rear pads on today. When I headed out to bed in the new pads the new chain is slipping under load on the upper 4 cogs of the cassette. Looks like I’ll ride the old chain to its bitter end at this point.

I tried my best to catch the chain wear early to avoid cassette replacement this time. How soon to you replace your chain?

0.5. And after 3 chains change the hyperglide cassette and chain. I run the Deore 12s hyperglide cassette, which is only AUD$100 at my LBS. So it's not worth mucking around.

Check your B screw tension before doing anything spendy. Shimnano drive trains are sensitive & a new chain changes the equation.
