3-Rensho (sa-n-re-n-sho) was established by Mr. Yoshi Konno who's younger brother of Mr. Hitoshi Konno (the founder of Cherubim).
Mr. Yoshi Konno had started the Cherubim cycle (former Cyclone) at Higashi-yamato city in 1973, and had announced the original brand Cyclone (shi-ku-ro-u-ne, not sa-i-ku-lo-n). Then the brand name had changed from "Cyclone" to "3-Rensho Cyclone", then from "3-Rensho Cyclone" to "3-Rensho".
The company developed the business which concentrated to track-racing model (pista) and road-racing model.

3-Rensho became one of famous custom bicycle brand in those days through supplying their frame to Keirin athletes or foreign athletes, making prototype model of lightweight bicycle, and exhibiting frame to New York show. Later the brand 3-Rensho Cyclone had disappeared. However, Mr. Makino who had worked at 3-Rensho established his own brand.

The catalog and the reference book for order were published around 1978 or 1979. But I introduce them as editions in 1979

The catalog was offered by Mr. K.S

This catalog was published in the late of 1978 and written in Japanese and English for New York show. The cover was so simple.

The inserted pinup: the athlete's name is Ryoji Abe who had won the bronze medal at the pro-sprint of the 1975 World Cycling Championship Liege (Belgium) for the first time as Japanese.

The catalog introduced 3-Rensho Cyclone. Mr. Yoshi Konno was also a bicycle athlete at the high school and the university and the business team.

This is the illustration which introduced the road-racing model. SR (Super-record) was introduced as a Shimano Dura-ace EX model, and ST (Standard) was a Shimano 600 EX model.

The catalog introduced the track-racing bicycle (pista) and the track-racing frame.
TR was full-order model (material, frame works, length). SR was size order model. And ST was easy-order model which was prepared six frame sizes.

From here, I show the order guide and the mail order guide. Both of them were published in the spring of 1978.

The guide book explained in detail about the order method through 4 pages from here. The page 1 and the page 2 are explaining about the complete bicycle and the frame specification and the price.

The page 3 was explaining about the standard specification, and the additional frame-works.

The page 4 was the chart of the frame skeleton and adaptation height.

The guide book was explaining about the mail@order through 6 pages from here. The page 1 was the summary.

The parts list which was recommended by 3-Rensho Cyclone was shown from page 2 to page 4.
The catalog was saying clearly that "As for some part, I don't use other than the listing parts". It must have been the policy as a frame builder.

This is the order sheet for frame skeleton. In the case ordering only a frame, a customer had to send only this application.

This is the parts order sheet. The estimate price to the budget was written on the sheet. The company wrote estimate price on the sheet which was sent by customer, and sent it back.

This is the specification of SR and TR frame. It was revised about the lug, the fork crown, the tip of seat stay, and the sticker.
The chart A indicated the standard specification. According to the chart A, the price of SR road-racing frame was 65,800 yen, and TR track-racing frame was 75,000 yen. The chart B indicated the additional specification. Customer could select the tube, the lugs, the fork crown, the frame-end and the several special frame works.

Back in those days, 3-Rensho had a big share in the bicycle competition market and had advertised their frame widely. The brand was basically for the competition. When they accepted an order, their attitude was as if saying "this is the place for professional".
