Quoted message said:My wife and I have taken up cycling for the first time since we were kids. She's bought a Saracen
Verve and I got a Saracen Rufftrax - nothing too expensive but they seemed OK to get us back into
cycling.
Both bikes have Shimano Tourney 21 speed gears. She's got Revo shifters and ID decks, I've got EZ
Fire controls and no ID decks.
Now the nights are drawing in I'm finding it increasingly difficult to see what gear I'm in. With
her ID decks, she's finding it much easier. I'm therefore interested in adding ID decks or
something similar to my bike. My Shimano ST-EF29 looks like it's got the same connection as hers
for connecting ID decks. It also boasts that it's CI-Deck Plus compatible.
I've not been able to find much detail on what options I've got for giving myself better
visibility of the gear positions. I haven't been able to confirm absolutely that I can add ID
decks to my Shimano ST-EF29, fine a supplier of them or find any supplier of this CD-Deck
Plus system.
All suggestions and comments welcome
I must admit to thinking that you have some priorities wrong here .. Why do you need to see what
'number' gear you're in ? Surely your legs, heart rate and general feeling of speed ought to tell
you what gear is appropriate, not what it's number should be .. 😉
Having said that, and admitting I have little clue what ID decks are, but surmise they're an
electronic 'gear indicator' type of thing, can't you simply unplug your wife's and try them for
fit on yours ?
I find my flightdeck computer (which integrates into my sti shifters) invaluable. However, this may
be a completely different thing to what the OP was enquiring about. It stops me getting it totally
wrong when changing up/down without realising I'm already on the biggest/smallest and should be
doing stuff with the front chainring. Also helps me avoid crossing the chain, and lets me plan for
hills better (by matching front and rear gearing well in advance but not dropping to far too low a
gear on the granny ring when I do it). If I'm in a given chainring I'm less prone to trying to fall
off the end of the back cogs these days by feel, but it's taking a while to learn.
I use them to avoid getting it horribly wrong and the ensuing chaos that causes (for me and anyone
near me, takes a few moments to get things sorted out with legs/gears). Using sti shifters mean it's
not like bar end shifts where it's (I think this is how they work) done by what position the little
switch thing is in - you move the sti lever to one way to notch up a gear, it returns, move again to
notch up another gear, etc. To drop gears, you push the lever the other way, and how far/how long
(not quite sure yet) you do it determines whether you drop down 1, 2, or 3, gears, therefore things
are a lot less predictable until you've done a lot of miles with them, and can lead to over-shifting
down and having to ramp back up if you're not careful. Having the display helps, cos it shows on
there as you're selecting the gears, which is a moment or two before the rear actually changes.
Regarding the OP's ideas - I don't know if he means a flightdeck computer or if this is some other
sort of indictator. If the former, then be aware that it has no backlight for use in the darker
conditions. Can't tell you at what point it becomes unreadable - not plucked up the courage to go
cycling in dusk/dark yet.
