Builder comment : Mr. Masami Otaki with KK.c speed
Frame design concept | Easy touring frame. |
Parts selection Concept |
Available + cheap chic. |
Points for appeal |
A simple and solid body with a small number of parts. |
Reconsiderations | Participation without understanding the purpose of JBT. |
Which team are interested in? |
07 Silk |
Others | I thought that the purpose of JTB was to propose a new touring bicycle, but I did not understand that the main purpose was to have a light body, which was decided by various additional points from the weight base. It was a good experience to participate in a completely away world. |
Rider Comment : Mr. Hiroshi Koyama
Impressions of the climbing section |
Should have either lowered the gear ratio a little more or increased the internal pressure of the front tires. |
Impressions of the Gravel Downhill |
It was boring with a simple gravel, but I was able to reconfirm that engine braking is superior to friction braking. |
What do you like? | The compatibility between the 650B wheel and the fixed gear was better than expected. |
Points to improve | Remove the rod type changer. |
