>Multi-purpose bike for all uses

TT120 is the first model and represents the core value of MONORAL BIKES. TT stands for Trail and Touring while 120 means 120mm travel for suspension fork.
It’s basically MTB with suspension fork but also good for touring. It’s designed with 27.5 semi fat tire (up to 70mm width) so the steering feel is as natural as with 700c gravel tire (up to 715mm) which diameter is close to it.
You enjoy downhill in the trail and long touring on the gravel and road with one bike. The uniqueness is the versatility, even more versatile than MTB at higher level. We call it Life riding bike. That’s is TT120.

>3AL-2.5 Ti tubing

Composite titanium tubing is used for shock absorption and light weight. The beautiful unpainted frame is rust proof and lasts a life time. Scratch can be easily removed by polishing. It weighs only 1700g (medium size), a lot lighter than a steel frame.

>Front derailer compatible

These days front derailers are old school but TT 120 can be installed a top pull front derailer with seat tube internal cable routing. It enables to have wider gearing for road touring.

>Multiple mount bosses

It has 4 bosses on the seat stay, 5 bosses on the down tube and 3 bosses on the seat tube. So you can install various types of racks and other accessories as you want. You can also install both a frame bag and bottles in the front triangle.

>Dropper post internal routing

Dropper post cable goes internal through the down tube.

>Convertible rear drop out

You can install either 142mm or 135 QR (optional) drop out according to your preference and a wheel set you have.

>44mm straight head tube

The common head set standard is used, compatible with both OS or tapered.
