以ˊ650b enduro 設計為出發點，同時有貪心想要有4X的特性共存，採用66度的龍頭角度，刻意降低五通的高度壓縮上管高度，軸距1115mm - 1130mm的可調勾爪，嘗試穩定性與靈活度的堅固，使用雷諾631的雙抽管材與銅焊技術製作。
The frame has been designed and hand built for 650b enduro bike. It's low, stable, and tough enough. The button bracket and top tube get lower, wheels length get shorter that could be more flexible. And the wheels length axle could be adjusted form 1115mm - 1130mm by adjustable dropouts.
