Great app. I don't see the point of multiple tabs though: since everything can be done in «manual» tab with the same time and effort spent. I would love to see hub gear data (nexus 3/5/7, alfine 8/11, etc) in the app!
Preselected options for selecting tyre sizes, chainrings and sprockets are very limited. No instructions for entering data manually, even though this is supposed to be possible. Unhelpful app.
Useful app so far. I'm not convinced by the categories nevertheless. It miss 8 speed cassettes and I wish I could save multiple bikes profile since I'm using manual option. (Is there a French translation planned?). Many thanks. Edit : Fifth star for the updates. Cheers
I think that the speed calculation is wrong on the tire size, a narrower tire should be able to go faster than a wider tire, however in this app when you select a narrower tire it significantly reduces the calculated speeds
Very good app, even though it doesn't have my tire size (65-396). Must have in trial discipline!
Nice and easy to use, very informative and helped with my new bike build
It is a very useful app to make comparisons between different bicycles
A very useful app to calculate the metric development of your bicycle and choose the best components according to a new update.
very good. only needs a save function
Exceptional calculator with many options!
Still I am testing this app, but at this moment, the app looks good, I'll change this opinion if in the future the app i don't like.
can't save last session
Great and useful app
No youth bikes.
it's useful app
limited options
Really disappointed. Totally time wasted as this app lack a lot of gears, tyres,... Even the most popular 14 - 28 cassette, the 38 - 48 crankset... Are not listed for road bike, as well as many others. And why you should make the list while you can let users enter the size of their casette, crankset... themselves, quite easy.
