Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Here's my inline indicator, on a bike fitted with Rival gearing.


It's simple. A clear glass tube reveals the cable inside, and a red (for visibility) rubber donut/washer/ring slips tightly over the cable and moves with the cable movement. Painted on the tube is a series of white marks that represent the 10 gears. Although made for Shimano, it does work with Sram, but with one hitch. Sram RD shift cables move a few millimeters more than the Shimano. What that translates to on the indicator is that it accurately accounts for only 9 of the 10 gears. If you shift into the extreme end on either side, the red ring resets itself to that extreme position and accurately indicates 9 gears beginning at that point. Since I rarely use my 28 sprocket, (11-28 cassette) it accurately measures the 11-25 gears. If I do shift into the 28, it resets itself to accurately measure 12-28 gears until I use the 11 gear, which then resets itself to accurately measure 11-25.

Like with my setup behind the handlebar, the idea is to have some kind of indication in front of you without having to look back. After just a short period of time getting used to how it indicates, I now know with a quick glance exactly where I am gear-wise at all times.

In case anyone is wondering, I use the Flight Deck for all other functions except cadence, which requires the computer to know the specific gears you are using, which is only possible using Flight Deck compatible Shimano brifters.

Interesting that this helped 7900 function better. Must be why teams were pulling it off their bikes. Because they could not face the peloton ridicule.

You would think if you know your speed and your know your cadence, you know what gear you are in.

I see what you did there. You're in a Biggest BF Idiot Contest with CR aren't you?

Hey, if it makes you feel any better RW, I don't always know what gear I'm in on my motorcycle either. And I've been riding it daily for five years. I want that to have a gear indicator too, but it's too much mojo to install an electronic one on that. My mechanical involvement on the ST extends to inflating the tires and pumping the gas.

Once you mount the indicator down and back by the stem, you may as well just look back at the cassette. Seriously though, I know I'm out of gears when it won't shift to the next one. Then it's time to HTFU and pedal through.

Also, why not just zip tie the computer to the stem?

You're even sillier than me. That's saying something right there.

I have to get a new garden hose. Now that you pointed out that it's Celeste, I can't look at it every day. I'll go mad.

2) No more wondering the exact grade. This thing works even if the bike is not moving


3) No more calling out to other riders


4) Cheaper alternative to DA plus bubble

Wow, didn't know those were still around. I got one with my DA 7700 levers back in 02 or 03 and actually put it on and used it until I changed out my cables and decided it was too cheesey. And with those levers it was actually right in your line of sight.

I guess everything comes back in fashion at some point.....

STFU.

In your particular case, that stands for Shut the Fred Up.

Might be worth a try. I've had nothing but trouble with Flight Deck since I switched from 9-speed (wired) to 10-speed (wireless) - computer continues to show speed and gears but the "time" function just stops working half way through the ride.

Oh, OK, a year ago it was standard on every pro bike on the planet with D.A. 7800, this year 'you can't believe it'. Don't you have food pics to post fatso?
