from trackstar website:

"This is Takuya ,KAZE Kyoto speaking.
How are you doing?
Is there anyone who ride Ganwell in the Trackstar?
There is a sad news to tell you.
Mr.Doi, the frame-builder of Ganwell passed away last week by the pancreatic problem. He was building frames until the day he was hospitalized.
This Sunday is his 60 years old birthday and it was also his retirement day. I have strong respect on Mr. Doi who spent all his life to make great bikes.
He was very proud that messengers around the world use his bikes among Keirin racers. Even he was a quiet guy, he was talking about that all the time.
If the rider of Ganwell send a message of condolence, that will make Doi's family and people of Ganwell feel proud."
