Why does everyone say that half lonks are cr*p, yes ill admit that the £13 half link on crc is pretty poor but to be honest you get what you pay for. Get a shadow conspiracy its pricey but awesome i had one on 2 different bike for two styles of riding (same chain just swapped it) and i havent had a problem. I went from jump/freeride to trials and i have never had a problem with it apart from the fact that i butched my chain link extractor making the chain shorter as the pins are very well fitted lol. Shadow conspiracy for the win .
