Yasei (野生) means "wild" in Japanese. Whether it's the characteristics of the rider or the terrain they're traversing, Yasei is an adventurous gravel bike suitable for paved and unpaved roads and longer trips.

...in my book for modern gravel bikes, plenty of key future-proof standards. A T47 threaded bottom bracket, a UDH universal derailleur hanger, flat mount disc brakes, 12mm thru-axles, and a 31.6mm seatpost with internal routing for a dropper.
Our frames are made of 3Al-2.5V seamless tubes in aerospace quality.
Titanium is more comfortable than steel due to its vibration absorption, but unlike steel it is lighter and will not rust. It boasts the strength of carbon, but unlike carbon, it can withstand rough handling. So we've made a frame that will last a lifetime. A frame you can adapt to the conditions and terrain of the moment.
The tapered head tube has integrated cable port on the left side. This makes the bike look clean, the cables don't rub against the head tube, and the integrated (drop-in) headset assembly is easy to maintain. In addition, we don't have to make unnecessary holes in the downtube.
Our frames are optionally equipped with a Cane Creek Angleset headset. This allows you to additionally change the fork angle in both directions by 0.5°, 1° or 1.5° depending on whether you want a more aggressive and agile or a slacker and safer geometry.
The Yasei is equipped with a carbon fork that can handle a lot. You can choose between 47 or 52 millimeters of rake, allowing for additional adjustments to the bike's geometry and behavior. There are 3 mounting points on the fork legs for attaching bottles or panniers for larger trips, with a load capacity of up to 3 kg on each side.
Wheels up to 28" or 29" diameter and up to 57mm (2.2") wide can be fitted to the frame thanks to the CNC machined chainstay yoke. This gives you plenty of flexibility on and off road. All you have to do is choose the right tyres.
The maximum single chainring size is 46T (42 - 44T in the case of an oval).
The frame is ready for a fully mechanical kit and internally wired dropper post. Thanks to cable port in the headset, there are no holes in the downtube.
The third bolt on the inner downtube is lower to let you mount single bottle closer to the BB. Or further from your framebag. Whaddyathink?
In addition to the usual inner triangle, you will find a pair of mounting points next to the BB and on the top of the toptube. It is also possible to fit a rear and front rack.
Slight horizontal ovalization of the toptube doesn't disturb the look of thin tubes. Looks great and makes the ride more comfortable adding a bit of vertical compliance. The bike is also more comfortable to carry in the hand or on the shoulder. And top tube bags don't twist as much. A pair of bolts that allow for strapless installation helps with that also.
Dropper is not just the domain of mountain bikes. You'll appreciate the ability to lower the saddle in the terrain even more on a taller gravel frame. Our frames are ready for 31.6 mm seatposts, so you have plenty of freedom of choice. Thanks to the fully internal routing, the control cable never leaves the frame.
The frame is ready for flat mount calipers, which are visually cleaner and more common on gravel kits. If for some reason you would like to mount post mount calipers, this can be done by installing an adapter. Both options are open to you.
The derailleur cable exits directly from the chainstay around the axle, adding to the clean look.
T47 is the emerging standard of the bottom bracket originally designed by Chris King. It is a classic threaded system, so there is no need to worry about unwanted sounds like with many pressfit systems. The larger diameter makes the whole system more durable, more reliable, and results in a stronger frame tube joint.
The UDH (Universal Derailleur Hanger) is SRAM's global standard. Therefore you can get it in any shop because it's not brand specific. It's simple to change and will rotate instead of bending in the event of a chain jam.
This also makes the frame ready for the new SRAM T-Type derailleurs.
For convenient service work, the right seatstay is fitted with a chain hanger. You're welcome.
For different frame sizes, we use different diameters of seat stays. Thanks to this, all owners can enjoy the same comfort, regardless of she size of their body.
