About a year and a half ago I scored a pair of Raleigh Twenties off of
E-pay. One was mostly ridable the second is a bit of a basket case. One
green and one brown. Anyhow both need overhaul as the chains are dry and
rather gritty; consequently I want to pull the chains off to clean and
re-lube them . My question is what sort of chain does it use? Is it
masterlinked? Or do I use a chainbreaker? I looked for a master link but I
didn't find one. (It didn't jump out at me)
The green one is the one that is in very good (ridable) condition and in
correspondence with Sheldon Brown I determined that the dynohub (Sturmey
Archer gh6) is missing parts (Bad news), but still generates power. After
very carefully dismantling it and regreasing it (this one had no oil port
on the axel housing) determined that the both right side and left side cones
are flat wrong for the hub. In face the left (small) side leaves the
bearings exposed! My long term goal is to follow Shedlon's example and
convert one or both of them into what I term "Product Improved" Raleigh
Twenties with one following the spirit of the classic English three-speed
(but more than likely do 8speeds with the Sturmey Archer 8 speed rear hub)
by being set up for commuting.
For the short term to get one back on the road I'm probably going to steal
the more conventional front wheel from the brown one and when funds become
available have a new wheelset created for each bike over time. Seeing the
green had an Sturmey Archer GH6 hub I'm inclined to try to stay close to the
original spirit of this particular bike and install an updated generatorhub
in it place along with new allow rims. My question on this is: Which
generator hub to use? I like the idea of using the new Sturmey Archer X-FDD
dynohub(Front dynohub with an integral drum brake) to keep an all English
flavor to the bike, but in researching what to do I read that dynohubs have
to be designed/optimzed to the wheel size the hub is going to used with. I
can't seem to find any specs for this Sturmey Archer to know if it would
work optimally on the 20" wheel size and the only manufacturer that seems to
make a "dynohub" for 20" 36 spoke wheels is SON; however, no one has a price
listed for this dyno hub. (And I'm suspecting it might be a case of if you
have to ask the price you probably can't afford it.). I would also consider
the Nexus, but it doesn't come as a 36 holer. What is the general consensus
on generator hubs? What would you do if you had a pair of Twenties to play
with?
