For the Voskhod fork, we specifically designed cast 8 mm dropouts from chromoly Japanese steel 4130. Casting not only made the fork more beautiful, but also allowed us to forget about the problem of dropouts torn off by unsuccessful grinds.


With the collective decision of the STRS team, the classic offset was chosen – 28mm. In our opinion, it is optimal for the absolute majority of riders who ride on the street and in the plazas.

The attachment area of the legs to the steerer tube – one of the most loaded places of the fork. To strengthen it, first we maximize the area of the seams  were legs welded to the steerer tube. This is a simple and effective solution. But this was not enough for us, so we pressed the aluminum spacer in the bottom of the steerer tube. This spacer makes the steerer tube harder and it helps to redistribute part of the load on the legs. Thus, the load is spread across the fork, and not concentrated at one point, which affects the strength.

a gain of strengths from redistributing the load on the surface of the fork 44%

There is not a single random detail in Voskhod fork. Most brands use a bolt with a thread diameter of 25mm. We reduced the bolt thread diameter to 24mm to make the steerer tube walls 30% thicker in the second most common place of breaking – the attachment point of the stem or the top headset bearing. By the way, we also thought about the convenience, the bolt at the Voskhod fork matches both 6mm and 8mm allen keys.
