[Closed] 1x11 when to change chain and which chain?

Get a chain checker, change at 0.75%, quite possibly too late. I use XX1 chains.

Someone mentioned paying under £20 for ther chains on the other recent thread.

I can only find a road chain for that kinda money.

I want at least a couple of chains so I can rotate them so a good price would be handy.

0.75% as per njee.

I'm using Ultegra 6700 10s chains quite happily - about £13 or £14.

There a few big XX1 threads here on STW and most people's thoughts seem to match Njee above and my own findings...

XX1 chain has by far worked the best for me. I previously swore by KMC and tried Shimano out of curiosity but nothing was quick as slick as the XX1 chain.

This is the only way to know when to change chains. Not everyone's miles are equal for wear and tear but changing a chain before it is too knackered seems to keep everything running well.

If you put a new chain on and it jumps all over the place then the old one was probably too worn- best thing to do here is run the old chain until it too starts skipping IMO.

I changed chains at 0.5 stretch (if I remembered to check!) but more often than not 0.75 stretch. I've stopped counting the number of chains I've used in the past year (at a guess I'd have to say 4 or 5) but the cassette still works perfectly with the new one I put on last week. The cassettes may be expensive but I've had far more life out of it than any other I've previously ridden- great bit of kit 😀

1x. XX1 chain ordered from CRC.....should I measure it up against the old one, or is there a magic formula for old people?

Park Tools chain checker they reccomend 0.5 on 11 speed

🙂

There are instructions to get the measurement right with the chain. Run around largest rear cog not through derailer and measure with suspension compressed then shorten. Thread correctly through derailer and join.
