Cyclists now have access to a new bicycle gear calculator for the Apple Watch. Spin the digital crown to choose your gear inches, and combinations of cog and chainrings are displayed below with the nearest match.

A force touch will open the tire size menu, and recalculate the gear entries based upon your selection. Use the gear menu to select the gears you own, and only those gear combinations will be displayed. This is especially handy for those of us who don't have every gear imaginable.

All combinations from chainring size 40-52 and cog 11-18 are calculated and displayed. Never carry a chart in your toolbox again!
