The individual gear ratios are calculated as with gear inches, using this radius ratio instead of the wheel size. You can calculate gain ratios, gear inches or meters development with my Online Gear Calculator or with your slide rule An Example: ...

If you're using a Schlumpf Drive plus an internal-gear rear hub you should enter the actual number of teeth of the front chainring for the first chainring, and this number of teeth times the Schlumpf ratio for the second chainring. The ratios are 0.40 for the Mountain Drive, 1.65 ...
the size ratios between the components, or the like. In the description provided below, the directions “front/forward” and “rear(ward)”, “left” and “right”, and “top/up(ward)” and “bottom/down(ward)” of the bicycle mean such directions as perceived by a rider sitting on th...
11. A control apparatus for an electrically operated bicycle transmission that has a plurality of gear ratios, wherein the apparatus comprises: a running condition time sensor that senses a time interval of a running condition of a bicycle; and a control unit operatively coupled to the running ...
Compact gearing worked well for a lot of riders, but never really lived up to its intended purpose of replacing triple cranks. Triples offered the option of getting ridiculously low gear ratios, but the compact double’s 34-tooth small ring (smaller rings mean lower gears on the front) wasn...
Bike Gear Calculator takes input on crank length, tire size, and gear ratios. Fill in the inputs, then watch it work its magic. It calculates speed and cadence figures. If you want to optimize your bike for your riding style or strength, this is the app to help you do it. ...
This unique layout aligns suspension forces in the most efficient layouts possible to enable frame designs with industry leading strength-to-weight ratios and stiffness. This structural advantage lets dw-link riders put down power more efficiently and track straight in the bumps where others veer off...
The benefits of the very slightly closer ratios of 10 speed over 8 or 9 speed are oversold. And I'm sure 9 speed components are cheaper than 10 speed, though I haven't checked. Oh dear, this is turning into TSR retrogrouch!
