Minivelo's unique looks.
Lightweight bike with high spec frame and fork.

Shock absorbing and lightweight for a comfortable ride

The SRV is a high-spec bike with an AL7005 aluminum frame, lightweight full carbon fork, and a finished weight of 8.3 kg, but at a surprisingly low price.

By sharing the main frame materials with higher grade models, the cost of preparing exclusive materials has been reduced.

Through various efforts, the components that are related to the performance of the frame have been designed with the following materials. down tube and seat tube are made of CSi top tube and head tube are made of FX frame material full carbon fork is the same as that of PK1

So there is no compromise in frame performance.

406 wheel size is adopted for a minivelo style. Its high-performance frame and funny 406 minivelo style give SRV an appealing look that can only be found on SRV.
