OLD RALEIGH CYCLE AND NEW COMPONENTS << HELP! >>
wy...@freenet.victoria.bc.ca
Fellow cyclists,
I have a 1973 Raleigh Gran Sport that I am trying to "upgrade" with
new Japanese components. Specifically, the crank, chain wheel, and
derailleur.
Folks at the local bike shop give me blank stares when I mention the
upgrade. They say that the bottom bracket threads are all wrong for this
type of upgrade. Basically, they imply that it can't be done! Is this
true?
I would surely like to breath some new life into the old steed, so if
anyone can help with this problem, please let me hear from you. Actual
part numbers for the Dura-Ace components to fit this cycle would be most
appreciated!
From the road,
Roger Peterson

Some Raleighs used proprietary threading (26 threads/inch) instead of
normal (24 threads/inch) for the headset and bottom bracket.
If your original bottom bracket cups are made to work with an open-end
wrench 16mm (5/8") or so, it is Raleigh thread. If the adjustable cup
has holes for a pin wrench, it is normal British/I.S.O. thread.
More information on this is available on my English 3-speed page at:
http://www.sheldonbrown.com/biz/hub/english_3_speeds.html
If you do have 26 tpi threading, you can use a Phil Wood bottom bracket
with appropriate rings, or use your existing cups with a nut-type axle,
or have the bb re-tapped to 24 tpi.
You will also need to spread the rear triangle, and may need to file
the dropout slots to fit the quick release axles.
If the frame doesn't have a built-in derailer hanger, you can get an
adaptor claw.

And please remember that all of this is pretty expensive in a non-returnable
way. If you like your bike and want to keep it then it becomes
a better bike if you put the money into it. If it's a junker that
you are going to get rid of as soon as you can afford a better
bike then maybe it's better to use the conversion money on a new
bike now.
On the other hand, Raleighs are nice bikes.

As an aside to this, my LBS told me last week that Phil has
recently gone out of business ! I had mae some comment
about using Phil Wood Green Grease somewhere it was maybe
overkill, and they responded that I'd better save it for a
rainy day, since Phil was now gone and the grease has now
become a very hard to buy item, wholesale.
Maybe they were just having a bit of a lark ? I sure hope
so. I bought a Phil Wood bottom bracket for my Trek touring
frame back, oh, more than 15 years ago. I rode cross USA,
cross Canada with my financee (we've got two kids now), and
generally used that bottom bracket to death - but it has never
altered from its original perfection. I always figured it
was the grease inside it, along with excellent seals.
No. He cannot have mine.

Phil Wood has stopped selling the grease but the company, now under new
ownership, has many products are still available. Phil has retired.

There was a big writeup recently in Bicycle Retailer & Industry
News about Phil Wood's plant relocating -- they were off-line for
a month or more, but there was nothing to suggest they were going
out of business, just having some trouble with backlog after
being shut down for so long in the move. (Seems they didn't
realize the new shop was wired 208 instead of 240, and couldn't
get any of their tools to work right....)
In any case, Phil Wood grease is nothing too special. Try some
Mobilith AW-2 -- same blue-green color, water resistant, and even
comes in little 3oz cartridges to fit mini grease guns. Not
identical, but pretty good grease from the same people who make
Phil's.

I'm looking for either John Forrester's address or the answer to this question.
In his book Effective Cycling, he talks about dissolving your chain wax
(paraffin) in łmineral spirits˛ and I want to know what exactly that
means...paint thinner, white gas (Coleman lamp fuel)
I've been an ardent hot-waxer but recently decided I wanted to carry it
with me on the road.
I've also heard of a German grease made specifically for melting into
wax for bike chains...a European racer told me it was hard like a brick of
cheese. If anyone knows of this and/or where to get it, please let me know.
chriss
ps...please reply to me at <csm...@compusmart.ab.ca> as I'm not on here
much and will likely miss a public reply unless you also cc it to me.
TIA
