After adjusting his enduro sled, the Tyee, in recent years, it was time for Propain to take a serious look at the platform and introduce some important improvements. Influenced by their experiences with their predecessors, and their first 29er, the Hugene, together with the valuable contribution of their World Cup relegation team, selected the most favorable driving characteristics and characteristics to form the Tyee 2020. Not wanting to compromise In no way, the new Tyee is available in 29 “and 27.5” versions, each with a dedicated frame.

To give you a little idea about the dedication of the small business and the enthusiasm of its employees, its CEO, Robert Krauss, is responsible for designing the new Tyee and most of the other bicycles in the history of Propain. Part of the Propain design process includes a launch meeting before the start of each new project, where all members of the company, all avid cyclists, are invited to give their opinion on which direction the new final product should take and what Features must be integrated.

Frame Details

The Tyee is available in carbon or aluminum for the 29 “and 27.5” versions. Propain uses its Blend Carbon process, which uses several carbon materials with different properties that are better suited to work in certain locations in the frame. Depending on the requirements of stiffness, flexibility, impact resistance, weight, strength or tension direction, different fibers and fabrics are used and combined to create a unique blend.

Using a similar process for aluminum with its Blend Alloy concept, different alloys are combined in a single frame. Propain uses at least three different alloys in a frame, and the tubes are generally made of a material more resistant to fatigue than forged or CNC machined parts. Parts that do not need to be welded together, such as links and shafts, are usually made of 7075 T6 aluminum, which offers very high strength, but is difficult to weld.

The weight of the carbon frame size M is 2,700 g without bumps, 3,700 g for the aluminum version.

Both aluminum and carbon have internal cable routing, but the carbon variant is also equipped with internal cable routing channels, which makes it very simple to route the cables and eliminates possible noise from the cables that hit the cables. frame walls.

The frame also features a threaded bottom bracket. Propain has developed its own system to join the ISCG brackets, by sliding an ISCG adapter into a counter-part of the CF aluminum bottom bracket or, respectively, the AL bottom bracket tube. That way, if a shock guard is mounted, the impact forces extend over a larger area, protecting the frame. In addition, if the frames are damaged, they can be easily replaced. Propain used its own test bench during the process of developing its frames, putting them under a load of 500,000 cycles, tested beyond their prescribed standards of performance, load and durability. The Tyee enduro model is listed in category five for unrestricted approval of the bicycle park.

Although the previous model had a protector that protected the rear shock absorber shaft from rear tire spraying, many people will appreciate the fact that the shock absorber is now hidden inside the main frame triangle. There is still enough space for a bottle cage assembly within that triangle.

A new descending tube protector and sheath protector for the Tyee has been formed. The sheath protector features soft, hollow ribs to reduce the slap noise. Acros bearings are further protected by Propain Dirt Shields, an additional seal on top of industrial bearings to protect them from dust, water and dirt.

With three frame colors for each tire size to choose from and multiple sticker options with traced vinyl paper (with a new combination of chrome colors in an already wide range), you can adjust the appearance of the Tyee to your liking. The color of the Mars Red Dark and Petrol frames are new, with the bright transparent layer of Carbon Raw that shows the various layers of the Blend Carbon structure. The raw aluminum style is now treated with a special coating, with a matte finish.

Geometry

29 “Tyee

27.5 “Tyee

There are three frame sizes available for 27.5 “and 29” models, although smaller wheels are available from S to L, larger wheels of sizes M to XL. Most measurements between 29 “and 27.5” differ only slightly.

A steep 77.1 degree seat tube angle supports the climbing capabilities of the bike. The head angle measures 64.5 degrees for all versions. The 29 “and 27.5” versions use forks with 42mm displacement and 170mm travel.

The range is modern but not too aggressive by current standards, it measures 431 mm in size S and moves 20 mm up for each size, up to 491 mm for an XL size.

The length of the steering tube is 15 mm shorter on large wheel models for comparable frame sizes. It is understandable that the battery remains about 20 mm higher for 29-inch bicycles. In addition, the length of the sheath is 445 mm for the 29 “version, and as Propain moved the shock absorber in front of the seat tube, they were able to shorten them to 430 mm on the 27.5” models.

Suspension design

Twelve years ago, the foundations for the PRO10 suspension concept were laid, a virtual pivot design with two counter-rotating links, which activate a floating shock from both sides. The new Tyee presents the latest evolution of that PRO10 system, placing the crash within the main triangle of the frame, compared to sitting between the rear wheel and the seat tube in the previous version, and provides 160 mm of rear wheel travel .

With regard to kinematics, Propain has been constantly optimizing the rear suspension ratio over the years to reach the point where they feel they have reached the ideal progression curve. Therefore, they decided not to make any changes in their latest edition.

Starting at a high ratio to improve sensitivity to small blows and with a strong digression (which offers a great progression in the rear) towards the second half of the path, the system is designed to withstand a proper beating and works well with blows of air and coil. same.

Although the leverage ratio remains the same, Propain was able to raise anti-squat values ​​from 70 to an average of approximately 110%, helping its pedaling efficiency.

specs

Each bike in the Propain line is fully customizable. However, there are some predefined packages available that can be adjusted. With its online configurator, multiple frame and decal colors, suspension elements, components and even handlebar heights and rod lengths are on the menu, allowing you to adjust the bike to your personal preference. The online ordering system has also been completely renovated.

The aluminum versions of the Tyee start at € 2,399 and reach € 6,974; Carbon models start at € 2,999 and go up to € 7,724.

You can request the new Tyee from now on in your online order store, with a regular delivery time of approximately 35 business days. Propain is also working hard to make its bicycles available for the North American market during the first quarter of 2020.

With 168 cm height, you could have chosen to mount a 27.5 “S or M model, or a medium 29” model. I opted for a size M of 29 “with air absorbers, which allowed me to adjust the suspension during my travels. Personally, I would not like to ride a bike with less than a range of 450 mm, if I had the option, so I also I would have chosen the median version of 27.5 “. The lengths of the seat tube could be a little shorter, since it could limit some people who run publications with droppers with a longer drop, depending on their crotch, as well as limit the option of raising a bit to a frame size larger, in case they look for a longer reach.

My 29er medium test bike with the Performance specification package, which includes a RockShox Lyrik Ultimate, a Super Deluxe Ultimate Air rear shock, aluminum wheels and mostly aluminum parts, had a total weight of 14.65 kg (32.3 lb) with pedals .

With the ferries acting as our main source for climbing the mountains, the climbing time aboard the new Tyee was limited. That limited time, however, was very informative, since it involved crawling along an awkwardly steep paved section, some challenging and quite loose uphill, as well as soft fire paths interspersed with hardpack sections and deep sand alike. As it turned out, the Tyee 29 turned out to be an excellent climber.

Equipped with an air discharge, there was no notable unwanted beating of the suspension, probably thanks in part to the anti-squat value of about 110 percent. Even when you pushed harder out of the saddle, it didn’t feel like your shock was replaced by a bowl of jelly. In general, version 29 “r accepted the speed changes voluntarily (which leads to the assumption that option 27.5 would even stand out in this category) and the bike always felt lighter than its weight on the scale would suggest, it is not that this value is bad at all for a 170/160 mm bicycle of this caliber.

I have never ridden Tyee’s predecessor, but maintaining the suspension’s kinematics and the same leverage ratio was a wise decision. The progressive nature of the rear allows the bike to run with a coil or an air crash, apparently without negative side effects … At least, I didn’t hear that any of my colleagues running a coil discharge complained.

I am a big fan of bicycles that increase steadily throughout the middle and final race to maintain support at higher speeds and during the greatest impacts of falls or jumps. Although the O-ring on the Tyee’s rear shock indicated that I used a full or almost complete trip throughout my runs regularly with my setup at approximately 33 percent, it never gave me the feeling that I had gone beyond of the capacity of the suspension. Falling to the floor, rolling hard after a steep descent or simply hitting the rocks, which we found a lot in our races on La Palma, never made me think twice about the functionality of the rear. Apart from that, while the soaking strikes thoroughly, the suspension always provided adequate feedback to the ground, which makes it easy to remove lips or other obstacles along the way.

It remained composed at higher speeds, and pushing the bike towards the corners is wonderful. With the surface predominantly loose on our trip, I found myself hitting the backside in sharp turns more frequently in those two days than in the last two months of my trip. The backside may not be as rigid as the previous one, but it is a melody that most Propain testers preferred, which reduces the talk slightly in rough sections. The very loose head angle of 64.5 degrees could suggest that the direction would be on the slow side, but the Tyee follows the pilot’s entrance quickly and voluntarily. For a fairly large bicycle with 29 “wheels, the new Tyee felt very alive and playful.

It is the sum of all the parts that makes a good bike excellent, and it is difficult to find something missing in the new Tyee, especially because there is an option for 29 “and 27.5” fans in carbon and aluminum. The seat tube could be a little shorter for a wider selection of frame sizes or dropper posts, depending on the height of the driver, but for many cyclists that will not be a big problem. In the end, the new Tyee simply allows you to do your thing in a wide range of driving conditions and speeds and doesn’t seem like a dead weight on the road uphill. And isn’t that exactly what enduro is about?
