My other bike is a 2013 Brodie Elan. With the stock setup (per here for as long as it stays there) it has a 26/36/48 tooth front chainring and a 9-speed Shimano Deore 11-32 tooth rear cassette. Based on this Shimano page (again for as long as it lasts) this is 11-12-14-16-18-21-24-28-32 (with a 34T variant available that runs 11-13-15-17-20-23-26-30-34). The following numbers are generated from the assumption that this matches reality.
(For discussion about the formulas, see Umbria100Gearing.)
The gear ratios, with combos I probably want to stick to bolded:
| front 1 | front 2 | front 3 | |
| rear 1 | 0.81 | 1.12 | 1.50 |
| rear 2 | 0.93 | 1.29 | 1.71 |
| rear 3 | 1.08 | 1.50 | 2.00 |
| rear 4 | 1.24 | 1.71 | 2.29 |
| rear 5 | 1.44 | 2.00 | 2.67 |
| rear 6 | 1.62 | 2.25 | 3.00 |
| rear 7 | 1.86 | 2.57 | 3.43 |
| rear 8 | 2.17 | 3.00 | 4.00 |
| rear 9 | 2.36 | 3.27 | 4.36 |
Km/h for cadences in various gears, based on a wheel size of 2205 mm:

Now, for my own use, the useful bits of the same information, namely the speed bands for each gear and my target speed in the gear. All of this is somewhat theoretical:

Realistically, with bar end shifters I barely know what gear I'm in so I'm just going to go at whatever feels right. This chart does feel more or less on from what I've observed.
Compared to my Umbria (although that info is now out of date again) I can stay in the middle front chainring much longer when I speed up. That's handy since shifting front chainrings is more of a pain with bar end shifters (my front chainring shifter is pure friction, not indexed).
