Half-step and granny.

Having read the following article: http://www.geocities.com/SiliconValley/Port/2945/Gears/Gears.html

I want to try the half-step and granny crankset setup describe below:

For my RANS Rocket I want a 53-50-30 crankset. (The Rocket comes with a 62-52-39 so I won't be
chaning the teeth count differential.) I have been experimenting a little the problem seems to be
the impossiblity of finding a front derailer which will allow this. A inner plate of the triple
front derailleur chain guide cage, because the plate is so deep, seems to get blocked by the middle
chainwheel when trying to shift into the large chainwheel.

I though of using a double derailleur since the inner plate is shallower. I thought that if I
loosening the low stop as much as I can, this might work but the double does not have enough travel
to accomodate the a triple crankset.

Does anyone know of derailleur which will allow this odd crankset setup? Has anyone had experience
with a half-step and granny setup?

Since Ultegras have replaceable chain guide cages, I was thinking of buying a Ultegra triple front
derailleur, but replacing the chain guide cage with a double's chain cage.

Does anyone know if the the mount of the replaceable chain cages allow for this swap?

Can anyone having both a double and triple Ultegra front derailleur take a look and tell me if they
judge the chain cages to be swapable?

 

Your 53 is so close to your 50, have you considered just going to a 2 chainwheel front?

While I can't comment on newer components, you should be able to find nos or used Huret Shimano, and
Suntour front derailers at your LBS or at an auction sight. Rivendell bicycles might also be worth a
try. They had an article in the Rivendell Reader some time ago about half step. I have half step on
my old Bridgestone touring wedgie, and it is quite elegant. My old Shimano unit has a sticker on it
that says "for half-step gearing."

In an era of 9 speed cassettes, half-step and its near perfect spacing isn't really necessary
anymore. One of the primary advantages for old touring bikes was a reduction in wheel dish and chain
deflection. With the advent of wider dropout spacing as a trickle-down from mountain bike
components, these advantages became somewhat irrelevant. Since the long chain line of a bent makes
chain deflection even more of a non-factor, I'm not sure what you hope to accomplish with half-step.
If it is the novelty of an old system that worked very well in its era, then by all means, go for
it. But if you expect to make any significant gain in useable gearing for your Rocket, I think
you will be disappointed.

Rob, who marvels at the dishless wheel of his Vision R40, but is still adjusting to the inability to
get out of the saddle for bumps to protect his wheel.

I have heard it said that with a little judicious work with a grinding wheel on a Dremel or similar,
a modern front mech can be modified to work with half-step gearing.

Gawd, that must be ancient. Shimano made "half-step" and "alpine" versions of the same front
derailleur in the late '80's. I think they were available in Deore and Deore XT grades.

ancient, hey...

oh nevermind. The derailler I was refering to is 1985. Doesn't really seem that long ago. It was
also match to the 'antelope' rear derailler with three jockey pulleys. Alas, my poor antelope died,
so I replaced with a Duopar. Those were the days of big chain wrap.

Geez... ancient *weird* parts- right down my alley. I used to have one of those Suntour LePree
3-pulley derailleurs: http://members.jcom.home.ne.jp/suntour/rd/arx3.html At least it worked better
than the Huret Duopar titanium rear that I had. I could never get the Duopar to work right.

The kids today don't know how good they got it.

Jeff

 

Ahhh, Jeff

Here I am, trying out this whole new thing, buying a recumbent to (prematurely) celebrate my 40
years, and you have me back on memory lane. I sitll have the old B-Stone with the eco version of the
duopar, which works great. Now that I have the R40, that poor old bike will probably collect some
dust. As one of the few true mass-market touring bicycles, I don't really want to let it go. Maybe
an occassional ride when I get over the comfort of sitting on this lawnchair with pedals.

I'll be 40 in May... but I've been around recumbents and HPV's since the late '70's and the Human
Powered Speed Championships at Ontario Motor Speedway. Now that I no longer work in the bike
business, I can afford some luxuries: a wife (OK, she's a necessity), 3 'bents, 2 uprights and a
garage full of bike parts. The only thing better than a recumbent bike is... two recumbents!!

OK, Rob, it sounds like your memories go back a ways.

Whenever I hear 'half step and granny' I think of Frank Berto, a writer for Bicycling magazine back,
in the days when it was a GREAT magazine. ( IMHO )

In my mind he has always been Mr. Half Step and, back in the early eighties, Bicycling magazine put
out a very nice, glossy, wall chart (I think it was an inducement to re-subscribe) that explained
his idea and showed all the combinations of gear inches for whichever sprocket/chainring combination
you were using.

Of course, in those days, bikes were 10 speeds. A chart of today's gearing, with 27 - 30 possible
gears, would be kind of a headache to follow.

Lewis,

Plus, the advantage of half-step gearing was more available gears with closer spacing between the
gears than the usual bike setup. I set up my Santana with a half-step and an 8 speed cluster in
1997. Even with a 11-32 eight speed, the tooth difference between the large and the middle chain
ring is 3 teeth. Hardly seems worth it. The Record road derailleur handles the front shifts
smoothly, even though it is 7 years old.

Nuthin' but wool socks nowadays. Vurry comfie.

Lewis,

Yes I remember it well. The younger, faster riders and the older wiser riders. At the time of those
tests I was a younger, not so wise rider. I ran a 14-19 straight block 6 on my Motobecane racing
bike. While it is trick for a High Schooler, I think I'm paying the price for it now. While I
haven't had any knee surgeries, my knees are a little tender when standing for the last five or six
years. Purchasing the Vision 40 for road riding should just about take care of this little problem.

It was not until a friend offered his Bridgestone T700 that I played with half-step, and my memory
served me well. I set up the T700 with an alpine 14-32 cluster and 24/44/48 chainrings. For those
who are really interested in playing with half-step, an old alpine cluster combined with a 4 tooth
difference is about the easiest way to set it up. (Typical alpine is 14-17-20-24-28)

I'm not sure what use my blathering is in relation to recumbents. With the advent of 9 speed
cassettes and dishless wheels, half-step is a wistful memory. It worked at least as well as having
all of those duplicate gears does now. But most folks didn't get the shift pattern (witness the
other posts questioning the small difference in chainring teeth). I wonder what ol' Frank thinks
about this new stuff.

Most of the problems weren't with the DuoPar itself. Most people didn't know how to orient them on
the hangers, I saw very few at 45 degrees to the ground.

Also they were designed to work with very little cable travel and high cable tension. Most people
used them with SunTour BarCon shifters, which were designed to work with derailleuers requiring a
lot of cable travel at low cable tension. When using them with a DuoPar you had to crank the
friction screw down to where the shifters no longer moved smoothly. So when you used the best
derailleur, with the best shifters, you got lousy shifting. Especially with closely spaced, wide
ratio cogs.

I wonder if Frank Berto ever figured out that his dislike of SunTour's Ultra 6 & 7 speed freewheels
stemed from his using BarCons with Huret and Shimano derailleurs.

I had a little business back then modifying DuoPars. See
http://bikesmithdesign.com/fittings/DuoParMods.jpg

1. Relocating the cable stop and anchor point further from the pivot, to change leverage, making
them compatable with BarCons. The one shown in the picture is the 7 speed version for those who
were "pushing the envelope". (To get Shimano to work well with BarCons, you needed a Simplex
Demultiplicator Relais, or to make a differential pulley.)

2. Adding a 3rd pulley (several years before the LePree)

3. Machining off the idler pulley cone to allow installation of Bulseye Pulleys. (The stock pulleys
had adjustable ball and cone bearings.

4. Raising the inner cage plate to keep the chain on if you backpedalled. (I sold some of these to
Lon Haldeman.)

I was getting $200 for a fully tricked out Ti version. Rather a lot for a derailleur back then, but
if you needed great wide ratio shifting, with the chains and cogs of the day, it was worth it.

Back to 1/2 step shifting.....

Whether it makes sense in a world with 9 speed cassettes depends on where you are. If you live in an
area where you will spend long periods at the same gradient and wind velocities are relatively
constant. (ie. Minnesota's Red River Valley) then it makes sense.

In rolling or urban terrain you would spend all your time shifting.

BTW Back in the Jurrassic era, I tried 1/3 step shifting, using a 14-34 5 speed and 44-47-50 rings.
Drove me nuts.

 

Hi, Rob, you say, "I wonder what ol' Frank thinks about this new stuff."

Yup, I hope he is still around to ponder these things.

I corresponded with him a couple of times while I was trying to set up my new bike with 'half-step'
and he always wrote back and treated me like I was his #1 project.

Have you tried Glucosamine Chondroitin for those tender knees? This stuff seems to help me.

Lewis,

Maybe I will give Glucosamine Chondroitin a try. I suspect I have some degeneration, although I
really haven't had a problem since I stopped standing up hills. For all the stink about not being
able to stand on a 'bent, I think it is probably healthier for your knees.

I missed out on the whole fixed gear fetish that is still going strong in the Twin Cities. I've yet
to see a express bike that wasn't a fixie in downtown Minneapolis. I wonder how they do it on hills.
Genetics, perhapps.

Anyway, thanks for the tip. My wife has been taking GC for a bunch of years, just had not really
thought of it as degeneration at this point.

I LOVE riding a fixed gear bike, Rob, although I don't do it often enough. :-(

The trick is to set it up so you can ride the local, steepest, hill.

For me, thats about a 42 - 17 and with this I can cruise along at 18 - 20mph without TOO
much effort.

They just feel very 'efficient' to me.

Lewis.
