1534.1 | Where I'd look first. | QUICKR::FISHER | Dictionary is not. | Wed May 09 1990 15:08 | 13 |
| If you want to modernize, have the frame cold-set to widen the rear
triangle. If not, I'd drop a dime to a few of the older bike shops to
see what they have in stock. Nault's in Manchester, NH, Gamache's in
Fitchburg, Goodale's in Nashua perhaps Wheelworks and the Bicycle
Exchange are some that come to mind. I would expect that you could
convert a 6 speed hub by dropping a spacer and changing the axle, if
you had to, though the shorter axle might be hard to come by too.
Then, too, there's a lot of kid bikes out there on 5 spd rear ends and
if you don't mind a lower quality part, you could use some of the
replacement parts for them.

For what it's worth, I have a 70's era Raleigh Competition that has
5 speed spacing, and I just spread the rear dropouts to accomodate
a 6 speed hub. Never had any problems with it.

1534.3 | brute force method? | JUPITR::BARWISE | | Thu May 10 1990 11:32 | 8 |

How did you go about spreading the dropouts? By hand, with tools..?
I'd almost opt for trying your method if I knew I wasn't going to
spread it too far or one side farther than the other.

1534.4 | Try it, you'll like it.... | MAMIE::CAMPBELL_S | | Thu May 10 1990 12:15 | 7 |

My "method" was just to put the wheel in position and then spread
the dropouts by hand untill the wheel slid in. You can do it by hand
as it will take very little force.
Good luck

1534.5 | Retro-fitting ? | MFGMEM::DERRICO | | Thu May 10 1990 13:08 | 17 |
| I'm sort of in the same predicament myself. I have an older
Fuji Special Tourer that I'd like to rebuild. I wasn't shure if
widening the rear dropouts by using a wider set would put too
much strain on the joints.
As far as 5-speed hubs, I think the only catalog that carries
them still is Nasbar, Performance doesn't even list them! I think
they are Suntour'.
I do have a question on the derailleurs: I have the OLD side
attatched derailleur instead of the newer version that bolts right
into the dropout. Is it possible to use the bracket from the old
one to mount a newer model? Or would I just have to go with a cheaper
model?

1534.6 | try to stick with 5-Speed spacing | TOOK::R_WOODBURY | | Thu May 10 1990 18:59 | 28 |
| re: .0 -
Last year I restored and upgraded my Atala touring bike I've had since
1970. It has Campy hubs, a five-speed (120mm) axle, etc. By carefully
choosing my gearing, I was able to get a good choice of ratios near my
average gear. This has eliminated any lingering desires for a 12- or
14-speed setup.
There are many 5-speed freewheels available (still!) which are as good
as or better than what was available 15-20 years ago. I chose a
Shimano, since I'm using SIS (the derailleur stops are turned in so I
only get 5 - instead of 6 - cogs).
Don't be mislead by what you hear - it's really not the hub shells that
are wider in many cases, it's just a longer axle with an additional
spacer. If you really want to, you can remove a spacer, and, if
required, cut an axle down.
One last thing, before you bend your frame: have you tried to find any
Suntour Ultra-six freewheels (requiring a narrower chain than the one
which came on your Moto). They fit on a 5-speed hub and give you 12
speeds.
The next time you're in a bike shop, pick up an issue of Velo-News. One
of the mail-order places was selling "old-style" Campy stuff.
Bon Chance!

1534.7 | a couple more ideas | ARCHER::GOODWIN_S | | Thu May 10 1990 21:46 | 16 |
| . Nashbar still sells Suntour Alpha 5-spd freewheels.
The down-side is that they aren't very high quality...
an ultra-6 might be a good choice if you can find one
because many modern chains have switched to the narrow
profile.
. Licktons mail order still sells Phil Wood 5-spd hubs.
These are top quality, but they aren't cheap either.
. I would not recommend spreading the drop-outs to
accomodate a 6-spd hub... you could end up with frame
alignment problems.
. Good luck in your search!

1534.8 | I suppose I'm just jealous | QUICKR::FISHER | Dictionary is not. | Fri May 11 1990 08:45 | 7 |
| Of course, if you keep the bike as a 10 speed, you will have a problem
with the 4 new terrain and wind combinations that have been invented in
the last decade.

1534.9 | the end...? | JUPITR::BARWISE | | Fri May 11 1990 12:57 | 20 |

I'll have to watch out for those new terrain and wind combinations!
As an update, I installed the six speed wheel from my wife's bike
onto my frame. I was easily able to spread the frame to fit the
wheel. Judging from how little pressure I had to use, I don't feel
it will add excessive stress to the tubing or joints. I think actual
cold re-alignment/bending of the frame would be more stressful since
the rear triangle would have to be bent past the point at which it is
now, in order for it to stay at the new width.
Also, I stopped in at Fritz's in West Boylston and they've got plenty
of 5 speed freewheels (also French-thread bottom brackets, but that's
another story!) Unless the wheel I tried from my wife's bike is somehow
different from the the norm, I am relieved and out of panic mode!
Thanks for all your help!!!

1534.10 | a British bike | ALLVAX::JROTH | It's a bush recording... | Fri May 11 1990 18:17 | 15 |
| I have a "Holdsworth Special", which has only 5 speed rear axle
spacing. Not too many people know what it is when they see it.
I have fenders mounted on it. Charlie Lamb (the BMB organizer)
calls it a "real randennours bike" :-)
I've never bothered to have the frame cold set to fix the rear wheel
spacing but may do it when I have the headset replaced (it has the
proverbial notch in it.) Hopefully someone competent can do
the work - (does Peter Moony do this kind of thing?)
It would probably be a good time to have the frame alignment checked
too. I'm embarassed to admit how many miles are on that frame. Long
live steel!

re: .10
Bicycle Alley (Webster Sq. in Worcester) does frame alignments. They
have a phamphlet describing the process and showing various options and

1534.12 | Hi E rims. | WMOIS::N_FLYE | | Wed Jun 20 1990 03:13 | 32 |

I have heard of Hi E hubs but not rims. I recently picked up a pair
for very cheap. I was told they were from the early to mid 70's.
By the looks of them they were very high tech at the time. They are
non-anodized tubular rims. Very light (9.6oz.). Sorry don't have my
conversion for grams. They are 36 hole and held together at the seam
by an aluminum insert and two rivets.
They are not extruded. The eyelets double as rivets to hold the two
sides of the rim together.

and held together with the eyelet.
Does anyone know anything else about Hi E rims?
