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 through 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.

Sheldon’s bicycle pages

Harriet has neatly reformatted Sheldon’s bicycle page. Read all about ’em. I find the page about his Greenspeed recumbent especially interesting. Who but Sheldon would be extolling the advantages of a low-rider tadpole recumbent tricycle for off-road riding?
