"Fully specialized for track bikes" and features a 4mm x 5mm hex wrench. Experience the new torque transmission feel of the X handle and the unique workability that is different from standard hex wrench designs.

The GENEX45 is an X-handled hex wrench equipped with 4mm and 5mm hex wrenches for tightening and loosening hex socket bolts. The GENEX45 is designed for setting up stems, handlebars, seat posts, and chainrings. The hex socket on the handle side is compatible with 5mm chainring bolts, which require the quickest turning. The bit side has 4mm and 5mm hex sockets on both sides, and length is 70mm. The surface is plated with hard chrome, which is the hardest electroplating and has excellent abrasion resistance for the finest finish.

The flat type has a non-slip knurled tip, which supports quick turning with the long handle wrench (5mm width). The GENEX45's bit is designed to be longer, so you can apply final tightening torque to the chainring bolt while holding the bit side.
If the bit is worn out, you can replace it.

The GENEX45 is a hex wrench that will also be used by mechanics from leading countries at the 2024 Paris Olympics. It was developed with the idea in mind of a wrench that professional mechanics would want to keep in the pockets while working in the busy infields of track stadiums, where they are constantly replacing parts and dealing with unexpected issues.

About Replacing the Head Cap
Depending on the task, the protruding head cap may interfere with parts or the frame, making it difficult to use the tool with the top cap still attached. In this case, use a set screw instead of the silver head cap to hold the 4mm x 5mm bit. The set screw is included with your purchase.
※2.5mm hex wrench is required for the set screw.

Excellent quality
Size: Large, Color: Purple
Perfect tuxedo to use for many functions. Got it about 2 years ago and have used it probably twice for galas as well as awards programs. Fits to size and didn’t break the bank. Texture is good and it is easy to pair with anything as well as is reusable.

The suit is amazing!! I just hate it arrived 3 days before prom after being delayed twice. It fit my son great, the blue was exactly as shown. It was not wrinkled or funny smelling at all. The material was very good and it will last a while. My son is 5’11, 150lbs, size medium

Misleading
Size: Small, Color: Brown
This is a very horrible material and poorly made suit, I have never bought anything this bad in amazon before, the crazy thing is that I returned this thing to get a refund and they shipped back the exact same garbage back to me. I clearly do not like anything about it, this is a misleading advert
