The NJS Bike Part 3



This is going to be a short one. Just to add I picked up a Nitto seatpost, SP72. Probably one of the most beautiful seatposts ever made. Still a little expensive @ $120; fortunately I found one used and in very good shape @ 1/2 the price. I also had some fun making some Bottom Bracket tools to R&R a Tange Steel Levin Bottom Bracket with a Tange NJS Alloy Levin Bottom Bracket.

These are the headset tools I made. The top is a headset cup remover, which is nothing more than a piece of 3/4" copper pipe with 4, 4" slits cut along the sides. All you need to do is pull the ends out a little and it works the same as the Stainless version (you work it into the head tube and pound out the cup). All this for about $2. The second is a headset press. The copper pieces are some plumbing adapters that fit a 1" headset to a "T"; the price is about $6.00. Generally I don't like to install headsets and only install the cups if they are steel. The cup remover worked like a charm.

The press takes a little more finesse, but it does work as long as your very careful. Would I trust myself and these tools on a Chris King? Uh, no. Would I use this system on a Cane Creek S2, which had some of the lightest and fragile cups on the market? What do you think?

This was a steel frame with very tough alloy NJS headset and it went on without any problem; the NJS stamp appears in the stem and headset photo; it is probably the smallest NJS stamp I have ever seen, but it is visible when you click on the photo.

Done!

The Soma Bike is Done!

Frame: Soma Rush (55cm); Fork: Threaded Tange steel; Headset: Tange Levin engraved; Bottom Bracket: Shimano Dura Ace (NJS) cups/bearings, Campagnolo spindle; Crank: Shimano Track (NJS); Pedals: MKS (NJS); Toeclips: Soma; Straps: Toshi; Handlebars: Nitto (NJS); Stem: Nitto (NJS); Rims: Tubular Araya (NJS); Spokes/Nipples: DT 15g; Hubs: Suzue Pro Max (NJS)Tires: Vittoria CX; Wheels: 3 cross front/ 4 cross rear; Cogs:18T (Soma), 16T (Shimano)(NJS); Seat post: Soma; Seat: Brooks; Brake caliper: Tektro; Brake lever: Soma.






















The bike is sleek, smooth and white. If using a NJS part made sense I used it, otherwise I went with Soma or Tange. I have a few more NJS parts but I perferred the bike this way. The saddle is a wonder. My best friend and riding buddy handed over this beautiful Brooks B17 Sprinter. For those of you that don't know, the Sprinter was the defacto saddle for track racers in the 50's. The saddle was introduced in the 1925 and was produced for 30 years. Brooks is now making a collectors version of the saddle with a Ti frame. It's a very cool saddle.


Is a bike really ever done? This post is over 4 months old and I'm still tweaking it. If you remember back @ http://onespeedbiker.blogspot.com/2007/11/njs-part-3-threadless-steerers-suck.html I said a $160 seatpost was over the top; and I still agree. However, what if you can get the $160 seatpost for say $60? and here it is! A Nitto SP72; considered by many the nicest seatpost ever made. Unless you are holding this seatpost in your hand, you can't imagine how nice it really is. The minor marks you see is the result of the seat post being inserted into a seat tube a couple of times. I bought it used from Japan for $67.20 shipped.

The Nishiki conversion; it lives!

This is part 2 of the  The Nishiki Conversion

A more intelligent person probably would have kept the frame and thrown the rest away. I still think that would have been easier. There are also some badly rusted chrome parts that did not clean up well. Still I really like the old Dia Comp parts. As usual as the build took shape some of my plans changed.

I discussed the wheels earlier, which are the original Araya 27” hoops and one Shimano 333 hub (front). The rear is a Formula loose ball fixed/fixed hub. Further I bought a Surly 22T cog and lockring. I also replaced all the spokes; the front spokes were extras from another build and the rear spokes came (along with some extra long nipples).

Frame wise, I ended up stripping off the my rattle can copper paint, which was an awful looking color for the frame anyway. I entertained trying the rattle can approach again with a different color and then came to my senses and took the frame to the powder coater. Okay, $100 is a bit much for this project, but I won't have to deal with it again and it will look really nice. My first choice was a burnished brass, but gold metallics require a clear coat and that’s another $60. Turns out my son got his first choice, with a dark green metallic (my other green bike is an emerald green).

Second there were these pedals. I actually threw away these OEM pedals (twice!) before I took a wire wheel to them and knocked off all the rust. Mechanically they work as a well as new, but the rust really did a job on the chrome. I was left obsessing over a set of Kyokuto pedals. I have seen them in several incarnations. The first is the all steel version I was dealing with, which include a strap guide on the outer edge of the cage. I tried using theses guides but they did not put strap in a postion that seemed shoe friendly. There is also NJS style, which have an abreviated aluminum cages. The NJS style also have rivets that hold on the cage on the body, all the other versions use a tab on the body through a slit in the cage. There is an aluminum caged version with no flip tab and another that does. I checked eaby for a better set, but had trouble finding a pair for less than $50. Then lo and behold I finally managed to find the above pair for $16.50. These have an aluminum cage with a flip tap.

The Nishiki also has a Suntour Sakae steel chromed headset. While in better condition than the pedals, the chrome on top lockring took the brunt of the corrosion. The lockring is also made for a 21.1 stem? The stem steps down from 22.1. After a little investigation I discovered this the use of a 21.1 stem is common on BMX and crusier. If I wanted a replacement, I would best look for a Crusier style headset. In the mena time I bought a similar style JIS Bottom bracket that tuned out to be mismarked (this was before I realized the need for a 21.1 top lock ring. I was able to send that back, but I replaced it with a much cheaper BMX headset, where the top lockring fit, but was a might puny. I may just stay with what I have (it's not THAT bad). The bottom bracket was in questionable condition with the spindle races being pretty shot, but the cups were pretty smooth. The owner of one of the LBS(s) in town, is a friend who lets me rummage around through most his old parts bins. He used to charge me a nominal fee, now he just lets me have them gratis. The original spindle had threaded studs at the ends and was asymmetrical. I found a replacement spindle and the short side fit pretty close, but I was hoping for perfection.

The Maxy crank has a pressed on 52 tooth chain ring and is therefore flat on the mounting side. To get a perfect chain line, I needed a spindle a few millimeters smaller. I poked around in the LBS and after trying about 8 spindles, I finally found one that gave me a 1mm gap. The Bottom Bracket itself was Tange, but there was something I didn’t like how the bearings (or the bearing cage) fit into the cups. I had some Sakae cups that seemed to like the bearing cages much better so I used them.

The chain was just an NOS Parts bin 3/32 KMC. The handle bar was a chromed Champion drop bar (this bike originally had a much narrower aluminum bar; but I happened upon this bar as a replacement) that is OEM on Nishiki(s) along with the Dia Compe center pull (770) brake caliper and the classic Dia Compe lever with the "safety" bar. The 770 brakes are still available and a good compromise for those who want cantilevers but don't have the bosses. The OEM seat was shot and I temporarily replaced it from the old parts bin seat.

I really like the look of the Dia Compe brake hanger and release. Rust really hurt the aesthetics of these parts, but I managed to find similar replacements on Ebay. OEM Replacements. The difference may not seem like much, but in real life it was worth the $20 extra dollars. The original budget was estimated @ $100. The was pretty much dashed when it turned out both hubs need to be replaced; fortunately a friend supplied me with a front hub gratis. Also the original paint job was supposed to be rattle can. When that didn't work out the budget was blown out of the water when I deceided to powder coat the frame.

Rear hub- $ 40
spokes/nipples $ 20
cog and lockring $ 50
Powder coat $100
Brake hanger $20
Pedals $25

So we're looking @ $235.

Still not done.
Nope. Since these photos were taken I have already added a grip to the handle bars and will soon add the new pedals. Also the old tires are trash. Fortunately 27" tires are dirt cheap. Finally I took the bike by an LBS that has helped me with some parts. After much appreciated praise, he had a question of criticism; where's the leather saddle? And of course he's right. A true hipster bike needs a leather (aka brooks/ ) saddle. For a while I have had my eye on a brooks B-17 Special; green w/copper rivets in mind. While you may see them for $80, they are back ordered. A search found the best one in stock for about $100. So;

Brooks seat- $100.00
Tires-$16

All the above items are on order. So I am probably looking at about $370 after tax and license. I will add more photos when it's together.


And here they are! As finished as it's likely to get.





My first ride on these tires show this bike to be a pig. That's right, at only 63 gear inches (52/22) it's like riding through the mud on smooth pavement. Of course, that doesn't really matter, it's all about the joy of riding it. OTOH the Brooks saddle is surprizingly comfortable. I didn't really expect much, so I am quite pleased.
