At first glance, the Tyee Carbon and Tyee AM Carbon are only slightly different from their predecessors. However, a closer look at the inner values and details reveals the many updates. The Tyee has been given a decent geometry update and benefits from useful innovations such as larger, sealed bearings, a new down tube protector, mud flaps and more space for other shocks.

The changes at a glance

• Geometry update with longer reach, steeper seat angle and slacker steering anglePropain Dirt Shield - double-sealed bearing covers
• Enlargement of the frame bearings to improve durability
• Omission of the front derailleur assembly
• Newly designed main frame and rear triangle with increased strength and stiffness
• New suspension layout with higher progression for improved performance and compatibility with steel shocks
• New down tube protection
• Larger mudguard keeps the shock nice and clean
• New vinyl decals in various new colors offer more options than ever before
• Category 5 rating with full bike park approval

The changes in detail

The seat angle has been increased to 76 degrees, giving the rider a more ergonomic position when riding uphill. The Tyee Carbon 2019 has a new main frame with an improved, more modern geometry. More reach and a slacker head angle (65 degrees) improve both the uphill and downhill characteristics.
The bottom bracket has been lowered slightly to improve the feeling of sitting "in" the bike as well as the handling.

One criticism of the previous Tyee was its limited compatibility with different shocks. The original design was intended exclusively for air shocks and restricted riders in their choice of shock. The 2019 model has a more progressive suspension and enough space to install steel spring shocks. This innovation makes it possible to get even better downhill characteristics out of the Tyee.

The following shocks, among others, fit the Tyee Carbon 2019:

• Rock Shox - Deluxe / Super Deluxe / various versions of the Super Deluxe Coil
• FOX - Float / Float DPX2
• Cane Creek - Double Barrel / Inline

In order to ensure that the kinematics are suitable for the more linear behavior of steel spring shocks, the overall progression of the transmission ratio was increased from 15 to 30 percent. The change to the kinematics also resulted in a more sensitive response at the beginning of the spring travel, improved support in the mid-travel range and increased bottoming out protection.

The anti-squat to prevent bobbing was set to around 75 percent on the predecessor model in the "climbing gears". Downshifting at higher speeds resulted in gradually less anti-squat, but higher chassis performance, which becomes increasingly important at higher speeds.
It proved to be a first-class chassis, offering a perfect combination of climbing efficiency and high-speed traction. Due to the higher sensitivity of steel shocks, the anti-squat of the new Tyee Carbon has been increased by around ten percent to ensure that the rear end remains as smooth as possible when cranking up.

New, improved production process

A new, improved process has been introduced for the Tyee Carbon 2019, which greatly limits the blurring of the carbon fiber and allows higher process pressures to be achieved. As a result, the carbon layers are not dragged along during the forming process, but can slide on the foam core and remain in position.
This leads to better fiber orientation and improved strength with smaller fluctuations. The higher process pressures strengthen the adhesive bonds between the carbon layers and thus reduce fluctuations in strength. Overall, the quality, strength and stiffness of the frames have been improved.

Equipment

As with all current models, Propain no longer offers customers fixed equipment. Propain only gives recommendations from start to performance to high-end, where the customer can still customize all parts according to their wishes. The Tyee Carbon is priced between 3,000 and 6,455 euros.

The "little brother" of the Chief makes no secret of its enduro genes. Some testers have called it a "trail enduro" in the past, and not without good reason. But it should not and does not want to define a new category. Rather, it is an extremely lively all-mountain bike with 145 millimetres of travel at the rear and added safety on the downhill. The Tyee AM Carbon also comes with three recommended specs ranging from 3,000 euros for the starter version to 6,300 euros for the high-end model.

The Tyee Carbon and the Tyee AM Carbon are now available in the Propain online store.
