Do you really have to have a half link chain
Is it so your wheel will sit right in short rear drops
I've heard losts of people have reliability issues with half link chains ( snapping) plus they're no lighter
You can get a high quality
really light weight conventional chain for the same price , ( It will last longer)
Shadow conspiricy were the first to mass produce a decent polished half linkchain , but many cheapos churned out since ( get what you pay for )
expect to pay around £20 plus for something good
