About to upgrade from 9speed sora to 105 5700 10speed

Will the chain length be the same?

Old chain is shimano HG53 (9 speed)

New chain - KMC X10 SL ( 10 speed)

Same number of links?
Cheers

    if the 2 big rings/cogs are the same size then yes

    read about chain sizeing on parktools or in the instructions that come with the chain.
    "Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

    Easiest way to determine chain length is to put the chain round the big ring at the front and the smallest ring at the back. In this gear the rear deraillieur cage should sit at 90 degrees to the ground (straight line up and down).

    According to Shimano in the big ring / small sprocket combo the jockey wheels should be vertically aligned (not the cage)
