Chain too wide for gap between chainring and chainring guard I have a Seek 0 2013 and recently the chain has been stretched so far that it needed to be replaced. On the Giant site it says that this is sold with a KMC Z51 1/2" * 3/32" chain.

I've since gone to two different shops who have both sold what appears to be the same sized chain (1/2" * 1/8") which isn't fitting, as it's too wide and brushes against the chainring guard. (This was dumb on my behalf and I have no defense for this.)

Is it possible to still use these chains (perhaps by adjusting / removing the chainring guard) without any complications in the future or are these chains simply the wrong size and I need to go return them and get the right chain?

So it should have a 3/32" chain.

1/8" = 4/32". That's more than 3/32".

Funny that.

1/8" chain isn't stronger unless you spend a lot of money on a high-spec track chain, which would have a more complex construction inside the rollers.

Get a 3/32" chain.
