For the production of STRESS bmx cranks, we used heat-treated steel of a Japanese Sanko brand. This is the best steel available on the market.
STRESS developed and introduced a gusset on cranks back in the 2013, which was produced to make cranks stronger, as well as to reduce the number of injuries to the medial malleolus. The gusset smoothes out the angles, practically excluding the possibility of getting a deep cut. For the production of the gusset, chromoly steel is used, which is cast in a special form. Then it is welded over the entire mounting area of the cranks to the spindle. Then the top of the seam is further polished to create a flat and smooth surface.
STRESS shortened the profile of the crank by 10% compared with the first version. According to their calculations, this change reduced the frequency of ankle injuries by about 40%.
