Finding BE Rims Just Got Tougher

来週、この記事の日本語版を投稿します。

When acquiring a "project bicycle" for restoration, chances are it will be in rough shape.

In the good old days rims where chrome plated much like chrome wheels today seen on high-end motorcycles or automobiles.  However, in the majority of cases the chrome will have rusted beyond restoration.

Even if the chrome is still there, typically the pads from the stirrup brakes will have worn through the chrome exposing the bare metal.P1040510

So most of the time the rims have to be replaced.  Finding a good pair of NOS (new old stock) chrome plated beaded edge rims is not easy.  However, until last year one could resort to purchasing a pair of stainless steel beaded edge rims from Araya
Not anymore.

I checked Araya's homepage recently and noticed that BE rims were missing from the product lineup.  I contacted Araya and discoved, much to my dismay, that the company dropped BE rims from their lineup and have discontinued production. 

Now Araya is known worldwide for its rims.  It began manufacturing wooden rims in 1903 and metal rims in 1914.  Since the first metal rims were beaded edge one can estimate that Araya's beaded edge rim manufacturing spanned about 95 years.

I did a little research and discovered that up until 1965 beaded edge rims were the most produced type of rim in Japan. Thereafter, the wired-on (WO) type of rim surpassed BE rim production.  Wired on tires were lighter weight and easier to change.

As noted in the diagram below BE tires completely encased the tire tube and rely on air pressure to keep the tire bead seated.  WO tires rely on a wire to keep the tire bead seated.

Basically, the four most popular sizes for adult full-size bicycles were:
26x 1" 1/4 (High end sports models)
26x 1" 3/8 (Basic utility model) Most common.
26x 1" 3/4 (Light carrier model)
26x 2"        (Heavy duty carrier model)

Apart from the overall condition of the chrome and size, there are two other main things to look for when searching for a good pair of NOS (New Old Stock) rims:  company or model logo and center lines.

(1)Company or model logo marks
Many of the old rims were manufactured with the bicycle company's logo which can be found between the first and second spoke hole on both sides of the valve stem.

Here is an example of a rim with the Maruka company logo.  Note that just below the valve stem is the manufacturer's stamp Araya.

Don't see much chrome on bicycles today. But 50+ years ago there were lots of chrome.  BE chrome rims add a nice touch.Img_9262_2Img_9271

Special thanks to S-san for sending in some of the photos for this post.
Next post will be the Japanese version of this one.  I'll be back with another English post soon, until then stay trued and happy wheels.

Shame aboutAraya. Guess I bought my rims at a good time. And they are indeed B/E.

Stainless always trumps chrome in my book.

Good timing JS.
From a functional standpoint stainless steel is definitely better since it won't rust and gives a little more resistance (braking power in the rain). However, from an aesthetic and original restoration standpoint chrome is the choice.
I agree if your restoration objective is to both ride and display, go stainless!

Genial fill someone in on and this post helped me alot in my college assignement. Thank you for your information.

Glad you find it helpful. Good luck with your college degree.

光号を特集に取り上げてもらい嬉しいです。
マーク数の統計楽しみです。写真撮影時は時間が無く、いったい幾つあるのだろう?と気になっていたところでした。宜しくおねがいします。

こちらこそ、写真を送って下さって嬉しいです。
光のフレームを持っているから、非常にいい勉強になります。
当時の自転車は素晴らしいが、今回の光号のようなオールオリジナルでいい状態の自転車は滅多に出ません。
写真を送って下さって、感謝しております。

こちらこそ、この道の有名サイトで多くのファンに見てもらえて光栄です。
よく見るとフロントフォークの上下にも消えかかってますが、光の転写マークが確認できます。あと4個追加になります。

確かに、フォークの金線引きの上下にありました!
前車輪の周辺だけで32個!
ありがとうございました。
