Rennstahl 991 SpeedGravel - Gravel Bike - Get Fast - 2023

Limits exist only in the head - Rennstahl 991 SpeedGravel

This bike is the union of two worlds, the road bike world and the gravel world. It is insanely fast on the road and also in light terrain. The frame offers the typical steel compliance in areas where it is desired. The result is a superior solution to the trade-off in bike frame design: the best balance of low overall weight, the ability to absorb bumps in the road, and yet an enormously uncompromisingly stiff and powerful frame, coupled with durability superior to any other frame material.

Details of the Rennstahl 991 SpeedGravel

The extreme strength of the stainless steel alloy makes it possible to draw tubes with wall thicknesses thinner than ever before, wall thicknesses as thin as 0.38 mm! The special chemical composition of this steel alloy produces superior fatigue strength while reducing the susceptibility to embrittlement from overheating in the weld zone.

This tube set is only slightly heavier than 6061 aluminum, while still providing the typical strength, durability and handling characteristics of steel. At the same time, this alloy is absolutely corrosion resistant, so that painting is not necessary here. Falkenjagd therefore polishes their frames very elaborately and then applies the lettering using a sandblasting process (special mixture of quartz sand and glass beads). The result: no varnish, no stickers, purism in its entirety!

Due to the focus of this very tube set on absolute weight advantages, it is predestined in particular for bicycle frames that are designed for hard racing use. The performance of the steel frames is thus in no way inferior to the downright fragile carbon frames.
