impressed! Was just tooling around in my man-cave and had to replace a worn-out front sprocket on my single speed. Downloaded the app to confirm my tune-up. Sure, the calculator can do the same thing, but this app is a lot more convenient! Easy to use to. When creating my own chart, it would reset after picking tire size and/or crank length. Can you include a magic gear calculator, ie gearing based on chainstay length, where a tensioner isn't necessary?!
Diesel or Dink Been looking for this. In the mid 70's it was all paper chart. I'm back and my how things have changed. Excellent app that allows you and everyone you share with to know whether you're a diesel or a dink. Diesel is back! Hey 20 somethings, at routine 80+- inches and 72+- cadence you want none of the old man and this app proves what map my ride already knows.
Good app, simple to use and visually appealing. It is not up to date with current trends in MTB: fatbikes, "plus" sized bikes and anything bigger than 2.35" tires are nowwhere to be found. I would strongly recommend that the developer add those "new" tires sizes (some of them have been around for over 10 years) so that the app keeps up with current trends in the bicycle industry.
Can't ask for more This is such a great calculator. It contains many options and features and best of all everything is arranged in such easy to use layout. This is by far better than all the web calculators I used (5). Thanks for making this calculator!
Godsend excellent app on my Galaxy S4 running 4.2.2 I just dont understand gearing . This app is divine I no longer have to know it tells me on all my bikes fixed and geared whether crankset or cogs will make a difference and by how much. I was thinking of changing both having read forums and now know what the gains are or not so saved the money and effort. Was surprised one of my changes would have made no change to speed a smaller crank arm. I am recommending it to all my friends. It's simple and informative even for me.
So So handy for faffing with setup. So handy and useful once setup on my moto g. You can select variants that apply to you and not even see the rest, and the multiple gear charts you can make are great if you have 6 bikes to set up. Well recommended. 5 star.
