Press Release: Propain Bicycles
Looking at things from a new perspective, being courageous and breaking new grounds, improve and develop yourself, start a new chapter – that was our vision for the new Tyee.
With the 2020 Tyee we have completely reinvented our Enduro bike. The ideas and experiences of the last years have flown into its development.
The result is a Tyee bike that meets 100% of the definition of an Enduro bike: a versatile and balanced bike that sets new standards, both uphill and downhill.The new Tyee is our next level Enduro!
Frame concept and PRO10
With his mission to develop the best frame concept, Robert Krauss laid the foundation for Propain 12 years ago and the PRO10 suspension system is the quintessence. It has been the heart of our Propain frames ever since and we trust in it 100%. The new Tyee features the latest evolution of the Pro10 system with the shock integrated in the front triangle. Don’t be fooled by the new looks, the good old Pro10 characteristics remain whilst further improving pedalling efficiency and weight balance.
New design concept
We are also breaking new grounds regarding the formal language. The new Tyee has an elegant, clean but also aggressive look. In the processing of the carbon we use the versatility of the material. Many visible edges and flowing shapes characterize the image of the Tyee. With a love of detail, we have created a design that is tidy, noble and puristic. Small accents give the frame its elegant and clean look.
DevelopmentOverall concept and geometry
New wheel size
We believe that an Enduro bike must be a true master of versatility. We achieved exactly that by combining a slack head angle of 65°, a very steep seat angle of 77.5°, a reach that gives room for movement, and a centrally located floating shock to concentrate the weight around a super low bottom bracket. The new Tyee provides pedalling efficiency with lots of pressure on the front wheel on the uphill and an optimum weight distribution on the downhill. A characteristic that you will notice right away when you get on the bike and never want to miss again. It’s amazing that this change in geometry has significantly improved both the uphill and downhill characteristics.
The long-awaited upgrade to our Tyee is here, 29” wheels! It took us a while, but we wanted to enter the 29” Enduro segment with a BANG. Of course, we also kept the 27.5” option for all fans of the smaller wheels.Every frame is optimized for the wheel size. It was designed to make the most out of the unique characteristics of the different wheels.Suspension travel
Front: 170mm; Rear: 160mmNew size concept
The 27.5″ option of the Tyee comes in the sizes S, M, L and addresses everyone who likes it more playful and agile. It also has a slightly shorter chain stay (430mm) than the 29″ option. The 29″ option is available in the sizes M, L and XL and aims at everyone who likes it fast and rough. The chain stay length remains at a moderate 445mm which ensures that the bike retains its agility and maneuverability.
The PRO10 system is known for its pedal efficiency, yet we were able to improve it by raising the anti-squat values from around 70% to 100%. Combined with the steep seat tube angle it really sets a new standard for climbing efficiency of enduro bikes. Whilst the rider can’t feel any suspension movement during pedalling the suspension stays completely active and reacts to the smallest bumps. Traction on the uphill is guaranteed.
The previous models of the Tyee have been optimized over the last years to find the ideal progression for the rear suspension. Last year we felt that we have reached an optimum which works incredibly well with both, air and coil shocks. Therefore, we chose not to change it and continued with the same suspension progression for the new Tyee.
Colors and decals
As before, the Propain logo can be chosen individually. So, everyone has the freedom to choose their favourite colour combination. A very robust, plotted vinyl foil is used for this. All current colours will be available further on.
New in the range is the decal in chrome and the frame colour Marsed Dark (glossy) and Petrol (matte). The Carbon Raw (glossy) gets a unique look through the clear varnish and the special processing of the Blend Carbon becomes visible.
Compared to its predecessor, the Aluminium Raw is now treated with a special clear sealant and stands out with its elegant matte finish.Frame colors Carbon

RawFrame FeaturesBlend Carbon
So, what’s unique about Blend Carbon? We believe that a great carbon bike is not made from a single kind of carbon material but from a blend of high-end carbon materials. If we would only use one kind of carbon material on the complete frame, we wouldn’t be able to make use of the various properties carbon raw materials do offer. On Propain bikes different resin-impregnated (prepreg) carbon layers are combined to a unique blend that is best suited for the job at a certain location on the frame. Depending on the requirements for stiffness, flexibility, impact resistance, weight, strength or stress direction, different fibres and cloths are used. Propain only blends the best of the best into their bike frames; prepreg material that is also used for airplane fuselages, wings and many other applications you trust in, probably with not even knowing about it.Blend Alloy
The same concept is also used for our aluminium frames. Here different alloys are used in one frame. A Blend Alloy frame consists of at least three different alloys. For example, the tubes of the frame are usually made of a more fatigue-resistant material than the forged or CNC-machined parts. Frame parts, such as rockers and axles, are usually made of 7075 T6 aluminum. These provide very high strength. Propain’s Blend Carbon and Blend Alloy are not fancy marketing terms, it describes Propain’s unique manufacturing process and is the reason for the light and durable frames we are known for.
Internal Routing with channel
Internal cable routing became a standard for modern bikes. It is the smartest, safest and, above all, the cleanest way to route the cables. We are taking this to a new level by equipping the carbon frames with internal cable channels in which the cables run. This makes the fitting super easy and any cable noise in the frame is eliminated.
Propain Dirt-Shield and Acros Bearings
Better safe than sorry! The robust Acros frame bearings are additionally protected by Propain Dirt-Shields. An additional seal that protects the bearings from dust, water and dirt.
Propain ISCG Mount
Also, the chain guide mount is a unique Propain design. This ISCG mount offers additional protection to the carbon frame. Hard impacts on the bash guard lead to a breakage at a predefined position on the exchangeable part of the ISCG mount. This protects the frame from the high forces during such impacts. Just like a derailleur hanger the ISCG can be replaced afterwards.
Internal chain stay protection and down tube protection
Optimum frame protection is key for Propain. Therefore a newly developed down tube and chain stay guard is used on the new Tyee. The chain stay guard is an entire new design which absorbs chain vibrations with the soft shapes on its surface.
The new Tyee frame is, as all our bikes, suitable for bottle cages.
The most common shocks are compatible and can be installed.

Specs and prices
We are and remain custom! Propain stands for custom bikes and each bike can be configured individually. Each bike is assembled by us in Vogt per order. The new configurator makes it even easier to build your dream bike. In addition we also offer three pre-spec’d models. Depending on the configuration, the alloy version is priced between € 2399 and approx. € 6974. The carbon version starts at € 2999 and ends at approx. € 7724.
Research and Development
During the development process our bikes are put through extensive tests on our own test bench. In lots of tests with a total of over 500,000 load cycles per frame, they are tested for performance, load and durability. All frames are tested far beyond the prescribed standards. Our enduro bikes, for example, are listed in category 5 and have unrestricted bike park approval.
