It may seem insignificant that Propain has eliminated the rattling noises. But our first impressions on the trails show: it's almost a new riding experience! All the rattling noise we've become accustomed to over the last twenty years has disappeared. What a relief!

The new background noise has been achieved by Propain with a new cable routing and with the support of the new Transmission rear derailleur from Sram. Together with Sixpack, the Propain tinkerers from southern Germany have developed a new stem that rides the handlebar cables into the frame via the spacer on the stem. The result is a tidy and noiseless cockpit.

The new Tyee also comes with other innovations. These can be classified as ongoing improvements to the Propain flagship. The reach has increased by five millimeters and the steering angle has been flattened by 0.4 degrees. At the same time, the frame height has been lowered by one centimeter so that long-travel dropper posts can also be used. In addition, Propain has increased the lateral stiffness of the frame, which adds 100 grams to the frame weight. The trend towards stiffer but slightly heavier bikes can be seen with almost all manufacturers. The reason for this is that bikes are being ridden harder and harder. The Tyee frame weighs in at 2.9 kilograms (size M).

Integrated rear brake

The integrated rear brake on the new Tyee has been beautifully implemented. It is designed to enable better power transmission. A practical feature is that no adapters are required for brake discs with a diameter of 180 and 203 millimetres. When changing the disc, only the position of the post mount needs to be rotated.

The new Tyee still has 160 millimetres of travel at the rear. Forks with 160 or 170 millimetres of travel can be fitted at the front. Propain is also expanding its potential customer base with the bike to include people with smaller body masses by also producing the new Tyee in size XS. Sizes XS and S are designed for 27.5-inch wheels. The frame size M is an all-rounder when it comes to wheels and allows 27.5 inch, 29 inch or the Mullet mix. The larger L and XL models are designed for 29-inch wheels.

An overview of the innovations:

The entry-level price of the Carbon-Tyee is just 3599 euros. The top version with all the bells and whistles including Sram Transmission comes in at 8244 euros. Propain is a direct shipper and delivers the bikes directly to the buyer's home via its online store.
