- i'm tempted to just give this answer:
Yes.
- but in reality you can get a little $9 indicator that fits in-line in the shift cable so you can get a visual indication of the current gear selected... (Nashbar had 'em a few months ago)...
- also, 'Flight Deck' means that if you use Shimano brifters and a Shimano cyclocomputer, you'll get a visual on the currently selected gear on the LCD... (not worth the $$$, IMHO)...
- but for those of us using cheaper 'puters, 'feel' is a pretty good indicator... i mean, either you're pedaling easy at a high cadence or not, right?
