Contemporary track cranks generally conform to the common chainline
standard of 42.5 mm., plus or minus .5 mm. It's a specification shared

As part of our online track catalogue, there's a reference page that
addresses many track-specific issues, including chainline, which you
may find helpful. The link direct to the page is
