rear mech went into the spokes on saturday and blew mech apart and twisted chain in two or three places. it’s only a deore chain and is less than 0.75% worn, so I recon a new chain will work on the cassette.

Is it worth splitting the chain to remove/replace the twisted links and rejoining with the same pins (I have enough links but only one fancy shimano joining pin), add two or three powerlinks or just get a new chain?

New chain. If you must use the old one use powerlinks. Original pins will last 5 mins if you are lucky. 3 powerlinks must be about the price of a Deore chain nearly?

Replace the whole thing.

replace it – with a sram one and get a free powerlink?

Otherwise, would you trust your nuts to your repair job next time you’re really cranking uphill?

stick it in the bin 🙁

I had this happen on a brand new Dura-ace chain, due to my impatient gear shifting whilst trying to chase a mate down…
