2 Speed Internally Geared Hub (Part 2)

次回この記事の日本語版を投稿します。

As mentioned in Part 1 I set out to build a rear wheel for my light carrier Sekine using a 2 speed internally geared hub, 26 x 1 3/4 BE rim and #13 gauge spokes.

Finding a 26 x 1 3/4 and #13 spokes is not easy.  I was fortunate enough to find a new old-stock rim manufactured by Ukai.


I ordered spokes from Hoshi Kogyo, established over 90 years ago and the only remaining Japanese spoke manufacturer.  #13 gauge spokes come in two varieties:
1. #13 gauge (2.3mm) with a 4.0mm head and 5.3mm neck, these take a #14 size nipple
2. #13 gauge (2.3mm) with a 4.6mm head and 6.0mm neck.

The photo below shows from top to bottom:
1. #14 (2.0mm)
2. #13 (2.3mm) with a 4mm head and 5.3mm neck, these take a #14 size nipple.
3. #13 gauge (2.3mm) with a 4.6mm head and 6.0mm neck and take a #13 size nipple..

The photo below shows a comparison between the two different types of #13 spokes (Top is a #13 gauge spoke with threads for #14 nipple, and, bottom is #13 gauge spoke with threads for #13 nipple.)

Since it has been awhile since I last built a wheel, I visited The Master
at his shop and he checked and gave me several invaluable pointers that I would have never come across in any articles or books, things that only come with time and experience.  I am indebted to The Master for his wealth of information.

Wheel truing. As is the case with old bicycles, old tools too are tough and made to last.

The completed wheel.  Next is to add tube and tire.

Next step, add tube and tire.
