I was at Kalavinka Cycles and Tanabe-san (the owner) was talking about the Konno brothers (there are five). He named them and told me what they were doing. Also, Yoshi Konno was Tanabe-san's "sempai" when he was racing in college. Yoshi Konno was in a partnership (Cyclone) at one time with one of his brothers (Cherubim) in Machida.

"(from tomity's email)
3Rensho was created with Mr.Yoshi Konno.
This is a transition of the name of 3Rensho.

Cherubim Cyclone > 3Rensho Cyclone > 3Rensho > Makino

Mr.Hitoshi Konnno (Cherubim):It retires by the cerebral infarction. The son
succeeds.

Mr.Yoshi Konnno (3 Rensho):It retires due to the traffic accident. Mr.Makino

It is what the above-mentioned I know. However, it is likely to differ the
fact and a little.
