「LSD（Long Slow Distance）」タラタラ走ることとは明確に違います ゆっくり走る練習だけど 時速「30〜35km/h」ギア比「2.8（ギア比=フロントチェンリング歯数÷リアスプロケット歯数）」ギアは固定して（変速は一切しない）ペースを維持し走る練習を指します このギア比（2.8）で固定して走る意味と理論は明確で 酸化系の筋繊維の増幅を図ることにより 赤血球の増加に伴うヘモグロビンが生成する機能の強化 筋繊維（1本づつ）へのアプローチ 命令系統（反射の除去 随意運動から不随意運動へ移行させる『脳のメモリーに刻み込む練習』）の練習 酸化系の筋繊維を使い切り順番通り（→中間繊維→OBLA→解糖系の筋繊維）脳で命令し随意運動することにより 内呼吸（酸化系の筋繊維でのガス交換）エネルギー供給の仕組み（ ...

I recently acquired a box full of old bicycle tools.
Tools are interesting, they are all designed with a specific purpose in mind; however, with old bicycle tools it is often difficult to figure out exactly what the tool was designed to do.? I have a few old tool catalogs which have been very helpful in uncovering the purpose of unfamiliar tools.? But catalog information is limited and I have had to rely on other sources to unravel mysterious tools.? In the past a fellow vintage Japanese bicycle enthusiast "ShigeP" over at しげP自転車の日記 ?(Japanese only), has enlisted the assistance of other enthusiasts to help solve a couple of mysteries.?
This mystery tool below was solved at ShigeP's blog and turned out to be a? rear drum brake adjustment tool for Honda Super Cub scooters .? In the old days, bicycle shops serviced not only bicycles but mopeds, scooters and motorcycles.
This mystery tool below turned out to ...

Here is a children's book entitled "The Bicycle" first published in May 1942, just six months into WWII.?
The book allows a glimpse of a nation at war and the need for everyone, including children, to conserve natural resources.

The "sen" currency was phased out in 1953, and the unit is now only used in interest rates and exchange rates.
Even has the child's name written in hiragana, Takako Okada.
First published in May 1942
The following are telltale signs of old Japanese books.
1. Opens from left to right.
2. Horizontal script is printed right to left.

This post is in reply to an email I received from a young enthusiast, George, who writes "I have what I believe to be a 1950's Yamaguchi bicycle but it doesn't have a stand.? I looked on your blog but was unable to find any information on stands, the types and differences, etc."
Well George, you are correct I have yet to do a post on stands.? But this one is for you and I hope it provides some insight.
Generally speaking, if we exclude the common day single leg side stand, there are basically 3 different types of stands:
1. Channel
2. Box
3. Roller-equipped?
1．Channel Type Stand
This is the most common type of stand found mainly on, gents' and ladies' roadsters , as well as, utility cycles .?
Equipped with springs the stand is kicked up and when lowered can be locked in the down (stand) position.
These stands come in two main designs, chain stay mounted or seat stay mounted.
Chain stay mount type
