Don't miss out if you want to look stylish with a chromoly hardtail!

It's no exaggeration to say that the UnAuthorized 33rpm has become synonymous with chromoly hardtail MTBs in Japan. The current lot is about 400g lighter than the first lot, and the ride quality is milder. The geometry has also been revised, improving front wheel lift on steep climbs. In addition, the top coat applied over the plated base makes it more resistant to rust.

We also offer custom builds

For front forks, 140mm to 160mm travel suspension is recommended.

The most popular is the 160mm travel OHLINS.

For those focused on downhill or strong racers, the 38 is recommended for its high rigidity.

For trail use, the lighter 36 is better.

While 29-inch wheels are standard, mullet setups are also acceptable.

We also have super deals on carbon wheels. Lighter wheels make bike control easier.

For components, you can choose between electronic or mechanical, whichever you prefer. However, it is not compatible with SRAM TRANSMISSION.

We also have used parts and unused parts taken from new bikes, so you can make good use of them according to your budget.

We look forward to discussing custom builds with you.
