Chainring shims

Shaims to reduce chain line. First of all for double chainring cranksets, but it is useful for conventional cranksets. By reducing the chain skew increases the service life of the chainring and the biggest cogs. If a chainring you have more wear on the outside than from the inside, then these washers will be helpful.
