Un Authorized 33rpm (7th) Frameset Unauthorized

The UnAuthorized 33rpm is a hardtail MTB recommended for people who:

　・Want to enjoy downhill rides
　・Want to tackle berms and jumps
　・Want to control their bike themselves while still benefiting from 29″ wheels
　・Believe that hardtails should always be made of "chromoly"
　・Don't quite feel right with typical overseas downhill hardtails

This frame can handle resort downhill courses, making it ideal for those who want to focus on downhill fun.

The rear is very short, allowing you to make tight turns with ease.

It also surprisingly glides smoothly on paved roads, making self-propelled travel unexpectedly enjoyable.

★SRAM AXS Full Mount Setting Conditions

*The 33rpm (7th generation) has a shorter chainstay length (RC) than the standard values set by SRAM for full mount operation confirmation, so the operational confirmation values were determined internally.

UnAuthorized 33rpm

About 20 years ago, the desire to simply pursue the fun of mountain biking with a hardtail was born.

The UnAuthorized 33rpm was created with the aim of becoming the ultimate trail bike.

Perhaps it is essential for the frame to be "localized" to Japan for Japanese riders to enjoy it here?

That thought led to the current UnAuthorized 33rpm.

After repeated updates, it is now in its 7th generation.
