STEX90

The STEX90 is a portable tool with a handle machined from solid steel on a lathe and equipped with fixed hex wrenches in 3, 4, 5, and 6mm sizes. Focusing on ease of use, it has been designed to be pocket-sized yet still provide ample torque. It's a popular item among riders of all genres, not just fixed-gear bikes, as it's convenient for adjusting saddles and handlebars.

The difference with the STEX that has been on the market for some time is that the direction of the bits on both ends has been rotated by 90 degrees, so that the bit on the other side does not interfere with the frame or chainring during work. This minor change has made it possible to continue the work that previously required repeated turning and removing.

Even if you think you have tightened the bolts firmly, they can come loose due to vibration. Small bolts are particularly prone to loosening around the saddle and handlebars, so be sure to perform regular maintenance.

If the hex bit becomes worn, you can purchase a replacement bit here . The bit is a through-type, fixed in place by tightening the screw in the center.

[Notes]

*Make sure to insert the tip of the hex wrench all the way in before applying torque. If you tighten the bolt without inserting it enough, the bolt may become stripped and damaged.
