I seem to have found that the half link in the chain is there to ensure that the chain is of optimum length when the bike is new - is that correct? When replacing the chain can a normal 520 with only whole links be used without any issues?

 

I have also noted that the Sherco parts fiches have gone from their website - As every dealer I have found links to these we don't seem to have access anymore - or am I looking in the wrong place?

 

Cheers

Possibly, it has been known for people to use a half link to keep the wheelbase short.  There's an easy way to find out - see how much slack there is if you align the chain as if the half link either was not there or was a full link - tie the links together with wire for this static experiment.

I find my bikes do need the half link to fit correctly and have never had a problem sourcing chain from a sherco dealer with the the half link pre-riveted into the loop. If you wish to omit the 1/2 link and your chainring is worn you could always resize by one tooth in either direction

If you intend to play around with rear or gearbox sprocket size you may need to reappraise chain length.?
