The Tyee is the golden ratio, the perfect balance within our product range, our flagship – the „chief“. The last evolution of the enduro has started a new era. With multiple test wins and numerous races won, the bike caught a lot of attention. With the development of the new Tyee, we were faced with one crucial question:
How do we make this bike even better?
With the unveiling of the 2023 Tyee, here at PROPAIN we are all in agreement – Hell YES, we did it!
We didn‘t set out to reinvent the Tyee – the challenge was to optimize it in the right places, to make a great bike even better! It was important to us that it remains unmistakably a Tyee at first glance. Nevertheless, the design has evolved with time, becoming more dynamic and balanced. Together with Sixpack, we approached the topic of cable integration from the ground up and are convinced that we have developed a solution that offers real benefits.
The entire cable routing has been redesigned, the reach has grown by 5 mm and the head angle has become 0.5° flatter. The frame height has dropped by 1 cm, so that long-travel dropper posts can be used without any concerns. The new rear triangle has more tire clearance and is 10% stiffer than before in both variants. The slightly increased lateral stiffness and the generally more robust construction of the carbon frame makes it 100 grams heavier than before. However, it still comes in at a very light 2.9 kg total weight in size M 29″ and offers just the right amount of compliance. In the aluminum frame, we have put a strong focus on weight and were able to save a total of almost 300 grams compared to the predecessor, so that the frame now has a total weight of 3.4 kg in size M 29″.
Even in times when trends play a major role in bike development, we remain 100% convinced that our PRO10 system represents the best frame concept and therefore remains the quintessence of PROPAIN. With newly designed links we slightly adjusted leverage ratio, pedal kickback, anti squat and the axle path. We are proud to say the PRO10 frame of the new Tyee is more capable than ever and at the same time remains extremely agile and efficient – The perfect balance!
When Acros approached us with their ICR headset, we were initially, to put it mildly, skeptical. But after the first test ride it was clear to us, that if we properly think it through, this concept is superior to classic cable routing in all aspects.
Together with Sixpack and Acros, we have developed a classic CNC machined stem, Made in Germany, that forms a molded fit to the top composite spacer. The cables therefore do not lead through the stem, but through the top spacer, through the headset, into the frame. This allows the stem to be switched effortlessly if necessary and the stem height can be adjusted by clip-in spacers without having to remove the stem at all.
Because we place great emphasis on customization, we offer two additional integration options in addition to our full integration. You can find more information on the product detail pages of the Tyee CF and Tyee AL.
We exclusively install Acros stainless steel headset bearings – recognizable through the red seal – in all Tyees. So even in the unlikely event that moisture enters the headset, longevity is ensured, and cables do not have to be cut due to wear in the system. All the other frame bearings in the Tyee are also Acros stainless steel bearings.
Absolute silence – the only thing you hear is the sound of the tires on the trail. To make this happen in addition to the cable integration at the headset, we optimized cable routing, going directly across the main pivot points of the rear triangle. We also developed new chain and seat stay protectors that are made of a soft TPR plastic with great damping properties. Air-filled nubs with an outward tilt stop chain vibrations with great efficiency, keeping the bike quiet on the roughest trails.
With the new Tyee, the Postmount brake mount is integrated into the rear triangle. In addition to the sleek aesthetic aspects, this also achieves better transfer of braking forces into the frame. For 180 mm and 200 mm rotors no additional adapters are needed, just a quick adjustment of the Postmount bracket is all that needs to make the switch.
Since our customers are able to customize bikes to fit their needs, we added a flip chip on the top link of the PRO10 system. This allows the new Tyee to switch between a pure 29“ configuration and a mixed wheel setup with minimal effort. The same geometry is maintained both in the mix and in the 29“ setup.
A good enduro bike of course needs the ability to carry enough hydration and the most necessary equipment for a tour or race right with the bike. The less weight in the backpack or hip bag the better. The bottlemount on the down tube and the toolmount on the bottom of the top tube provide the perfect basis for this.
We believe that a great carbon bike is not made from a single kind of carbon fiber but from a blend of high-end carbon materials. If we only used one kind of carbon material on our frames, we wouldn’t be able to optimize the various properties of different carbon raw materials. PROPAIN bikes use many different prepreg carbon layers that are combined to a unique blend that improves ride qualities of certain location on the frame. Depending on the requirements for stiffness, flexibility, impact resistance, weight, strength or stress direction different carbon layers are used. PROPAIN uses the highest quality blends in our bicycle frames, the same prepreg material that is used for airplane fuselages, wings and many other applications you trust in.
The same concept is used on our aluminum frames, where different alloys are combined in a single frame. Our tubes are made from a more fatigue resistant material than the forged or CNC machined parts. Parts that don’t need to be welded are made from 7075 T6 aluminum which is difficult to weld but offers very high strength. A Blend Alloy frame consists of a minimum of three different alloys and is not a fancy marketing word for the same thing everyone is doing. It describes PROPAIN‘s unique manufacturing method and is the reason for the light and durable frames we are famous for.
The new Tyee continues to come with 160 mm of travel in the rear and the option to use both 160 mm and 170 mm forks in the front.
The PRO10 system is known for its drive neutrality. The latest iteration of the frame concept also lives up to this expectation with an anti-squat in SAG of 113%. This means the system retains its sensitive response and begins to work even on the smallest bumps. The progression of the frame has been optimized and improved over the years. Due to the minimal lower end progression of the new PRO10 system, it continues to offer the best basis for coil shocks, but at the same time perfectly works with air shocks. This way, it delivers optimum grip and support with both shock options at all times. The PRO10 frame of the new Tyee offers a ratio of capability, agility and efficiency that has never been achieved before.
We are thrilled to offer the new Tyee in size XS for the first time for smaller riders looking for a bigger bike feel. The sizes XS and S are available exclusively in a pure 27.5“ configuration. Size M is available in 27.5“ and 29“ frames, plus the use of the flip chip the 29“ frame can also be ridden in a mixed wheel setup. The sizes L and XL can be configured in Mix and 29“.
During the development, our frames are extensively tested on the test benches at our HQ in Vogt, Germany. During load tests, with a total of over 500,000 load cycles per frame, they are punished to ensure the best performance, load and longevity. All frames are tested far beyond regulatory standards, resulting in our enduro bikes being listed in category 5 and having unrestricted bike park clearance.
