I replaced the chain on my XR today and while the chain came with a rivet type link I used a clip type master link I had since this was what the old chain used. This thread http://www.advrider.com/forums/showthread.php?t=331112 got me thinking though. Should I have used the supplied rivetted link ? The clip master link I used was the correct size but an O ring instead of the chain's X ring - any issues there I should be aware of ? As a general question, what are the benefits of each type of master link - I have had the chain snap twice on my XR and both times it was the clip-style master link that failed. I wonder if a rivet type link wouldn't better - why do people use clip type links ?
