User reviews

App closes when any button within settings is touched.

The app will not allow any changes to the preloaded ratios, it won’t allow you to upgrade from within the app either, It will crash, or close upon button press.

Outdated, doesn't support 12 speed cassettes

Very simple cadence/speed graph. Useful, but doesn't have 12 speed cassette support.

Yes, it DOES do modern setups!

I’ve used this app on and off for years and it’s the only one I’ve found that gives you a graphic display of your gear ratios. The app allows you to save up to five configurations with different chainring and cassette combinations and, for example, do “what-ifs” to an existing setup, which can be very useful when considering an upgrade.

There are two reviews on here that tell you the app is outdated (“in the dark ages”) because it doesn’t list the latest cassettes or chainring setups. Oh dear! Are they so “up to date” that they can’t do anything for themselves? If the guy wants a 1x chainring and it isn’t listed then all he has to do is create his own “custom” one. Yes, it takes a lot of effort because he has to press the “+” button, type a name for it then type the number of teeth it has, which can take a novice nearly 15 seconds, but he’ll soon find he can get this down to down to 10 seconds or less with a little practice. When he’s mastered creating his 1x chainring he can do the same for his “modern” wide-range cassettes. Who knows, it might give him the confidence to blow-up his own tyres!

This app is really good but it could be tweaked slightly to be even better. It needs to accommodate 12 speed cassettes (it only goes up to 11 at the moment), and the option to display two setups side-by-side would be nice. But don’t be put off by these unnecessarily bad reviews; they say more about the reviewers than this app.

Very useful

Was able to enter custom rings and cassette from an older MTB as I'm shopping for a different cassette, and this app works wonderfully. Only flaw I found so far is that the Gain graphs seem off, probably because it doesn't have a setting for crank length. I'm basing my decision mostly on cadence though, so gain is just a curiosity really. Thanks for this app!

Serious needs updating

Useful app in theory, but needs updating to reflect current gear set tends. No wider range 11 speed cassettes, 11-28, 11-32 and 11-34 are now common for road bikes. No options for the new 1x gear sets at all.
I don’t recommend that you spend anything on this to “unlock” the additional features. Stuck in the dark ages, obviously developed by cyclists with knackered knees who grind up every hill.
It’s 2018, not 2008.

FAQ

What is Gear Ratio Calculator Lite used for?

Gear Ratio Calculator Lite helps cyclists calculate and visualize gear ratios for road bikes and mountain bikes. It aids in simulating different gear combinations and selecting optimal replacement parts by providing detailed charts and graphs.

What types of bikes does Gear Ratio Calculator Lite support?

This application is designed to calculate gear ratios for both road bikes and mountain bikes (MTB). It offers a wide range of options for chainwheels, sprockets, and tires to simulate various configurations.

Can I see how different gears affect my speed and cadence?

Yes, Gear Ratio Calculator Lite allows you to create graphs displaying speed (in km/h, mph, or m/s) against cadence (rpm). This helps you visualize how changes in gear position affect your speed at different pedaling rates.

How does Gear Ratio Calculator Lite help with choosing parts?

By simulating various gear combinations and displaying their impact on speed and cadence, the app helps you identify the gear ratios that best match your desired performance range. This makes it easier to choose satisfying replacement parts.

What is the 'Gain Ratio' in Gear Ratio Calculator Lite?

The Gain Ratio calculates and displays the distance your bike travels for each full revolution of the crank. This metric is useful for understanding how efficiently your bike's gearing translates pedal strokes into forward motion.

Is Gear Ratio Calculator Lite available on all devices?

Gear Ratio Calculator Lite is supported on iPhone, iPad, and iPod devices. It is designed for Apple's iOS ecosystem.

How often is Gear Ratio Calculator Lite updated?

The application was last updated on September 15, 2017, with version 3.4.0. While it has not received recent updates, it offers a stable set of features for gear ratio calculations.
