This hand built frame is designed to your individual requirements. Each plate has been reviewed and analysed to ensure any excess weight is removed while maintaining reliability.

The Sub4 glides effortlessly due to the lightweight and rigid frame, but don’t think we have compromised on quality.  The Sub4 boasts all the same reliability features as the TIGA, and with the frame being very similar in design and materials, you can be sure the Sub4 isn’t just super light, but it’s super strong too!
