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.
Gear Calculator updated!
Our gear calculator is now updated to cover the newest cassettes from Shimano, SRAM and SunRace. — Still to update: the French- and German-language versions.

Additions to the Gear Calculator
New crank lengths have been added to the Gear Calculator and Internal Gear Calculator, so they can calculate gain ratios for children’s bicycles with cranks down to 100 mm (less than 4 inches).

Fatbike sizes: 26 inch tires, 26 x 3.8, 4.0, 4.25, 4.7
