Updates to chainline and frame-spacing pages.
As of 2018, fatbikes and disk brakes have led to several new axle-length standards. The problem of disk brakes’ pulling the hub out of the front dropouts has been addressed with thru axles, which insert into a fork with a hole rather than a slot at the end of each blade. Our chainline page and cribsheet as well as our frame spacing page and cribsheet are now updated to cover these developments.
