need shifters

David McDivitt said:

I just paid $60 for a Sekai CT Deluxe 2700. Anyone know
when it was made? The rims and tires are very thin, but
perfectly straight! The bike is very lightweight, too, for
a steel frame, and is in near mint condition.

Problem is there are no shifters. The front and rear
derailleurs are present, but the shift wires are clean
cut, dangle, and go two-thirds of the way up the lower
frame bar.

I don't want to get old-style friction type shifters. I
have a Cannondale mountain bike which I also got recently.
It has perfect rims, too. Anyway, on the Cannondale, there
are two levers for each derailleur. One lever shifts up
and the other down.

For the Sekai I was thinking I could extend the shift
wires or just replace them, and make them long enough to
go up on top of the handlebars. If possible I'd like to
have something similar to the Cannondale. The Sekai has
five speeds on the back and two on the front. Suggestions
would be appreciated.

If you have five speed, it's designed as friction shift
only. A six-speed Shimano downtube shifter sort of works
with five speed if you "dwell" on the shifter a little to
make the chain change sprocket - these sprockets don't have
all the fancy modern ramps and cutouts - but there's no
real point.

Like Zog, I believe you have a mech that pre-dated indexed
shifting, you may be able to locate some old Shimano
thumbshifters that have both indexed and friction mode which
will work fine in friction mode. My old MTB had some Deore
ones dating from the mid eighties

Thanks. Where is a good place online to view shifters? I
looked at several parts places but saw few shifters.

If I do not want friction shifters I assume I can change the
derailleurs to something else. What would be good
derailleurs to get? I do not want the shifters on the down
tube but up on the handlebars.

I used to ride a bike all the time when I was a kid. Want to
go on rides with friends so I can get exercise. Hate
exercise machines.

The guy at a local bike shop said a 7 speed derailleur would
cost $15, and a 7 speed sprocket $15. He said a more
expensive derailleur would be $30, but there would be hardly
any difference except weight. Index shifters for up top
would be $20. The derailleur would be a Shimano Tourney and
the shifters Sunrace. So for $50 I can convert the 10 speed
Sekai into 14 speed with index shifter. I asked about
sprocket width and he said it is the same as the five speed
already on the bike and the same chain would work. Would
this stuff work OK? Price seems OK.

That frame was made by Yamaguchi Frame, Osaka from Tange
butted tube, Nikko Sangyo lugs and forged Suntour ends.

You probably have room for a standard SunRace or Shimano six
speed freewheel. That, a basic SIS type rear changer ($15 to
$30) and a chain would make your bike compatible with top-
mount six speed index levers($20). That's the cheapest,
simplest route to index on that bike.

Other formats will involve redishing the wheel for a seven
speed freehweel or replacing/rebuilding with a cassette hub
to go nine or ten speed (eight being pointless).

What do you expect of this bike? A Campagnolo Ergo setup
would require shifters, rear changer, hub, cassette, chain
and a wheel rebuild but the result would be great:
yellowjersey.orgergokit.htmlOpen ↗ for example.

Your bike's long horizontal ends would also lend themselves
to a fixed gear project.

You mention a mountain bike shifter. Did you mean to imply a
straight-bar format?

The serial number of the Sekai is 76294923. Does not with a
"Y". What year? What do you mean by "long horizontal ends"
and "fixed gear project"?
**************

Thanks for the info, Andrew. I posted another message in
this thread about changing the rear derailleur and sprocket
to seven speed. The bike shop guy said I could go six or
seven and use the same shifter, but change the cam in the
shifter for six.

I wanted to do some biking. I was going to go out last week
and buy something. Thought I'd go to Sears and if I liked
something, good. I called one of my wife's friends, to get a
phone number for one of her other friends, to get her
boyfriend's number and get his advice. He has a bike fixing
hobby. The first friend happened to have a Cannondale, ten
or twelve years old. I didn't know if I wanted a mountain
bike, but it was a good bike. I redid the bearings, but the
bearing races in the bottom bracket were pitted. When
reassembled the peddles would make a popping noise.

I found new bottom bracket parts, spindle, races, and
bearings for $20. But while there I saw a real nice bike for
$60, sitting alongside others going for $900 to $3100. It
was being sold on consignment. It appeared to be in perfect
shape and had been lowered from $120. The rims were perfect.
The tires were flat, but I was told they would hold air.
Also, there were no shifters, but there were derailleurs.
After thinking a long time I decided to go ahead. It's not
that I couldn't afford it. I just didn't want another item
sitting around.

I've been doing research since buying the two bikes. The
Cannondale has an integrated brake and shifter. The shifter
is on a flange coming off the brake, and could easily have
been mounted by itself, but the designers chose to make it
all one piece. What's really cool is that each shifter has
two levers. One shifts up and the other down. It would be
nice if I could put such on the Sekai.

I plan on using the Cannondale for trails and the Sekai for
pavement. I realize now I need to get two new seats, one for
each. I am enjoying getting up on new terminology since I
last rode bicycles 35 years ago.

Spending $50 on the Sekai seems best for seven speed
sprocket, derailleur, and shifters. If I have a choice
between six or seven speeds, and if each takes the same
space as the five speed sprocket I have, is there a reason
not to get seven? Thanks

-snip a lot because after extensive top posting it was hard
to sort out.-

It's a 1977 . The "Y" was added in later years. Sure, seven
is a more-widely-supported format . and about the same price
for parts.

But, as I noted earlier, a 1976 bike will need some axle
spacing and a redish to use a seven freewheel.

The frame ends are long ( over an inch) and horizontal ( not
vertical) so if you wanted to build a fixed gear bike this
would be a good frame for that. Here is the next model up -
very similar styling:

are, IIRC, Suntour and even longer.

The picture shows a nice bike. Mine is same except paint is
not as elaborate, and light blue. Thanks for info
