Bicycle Set 15, 5 pieces The ultra compact and lightweight bike tools with two quadruple bits and three tyre jacks. Four different screw profiles can be operated with just one bit. Significant weight savings of over 50 %. The enormous space savings make the Bicycle Set 15 perfect for mobile use. The operability of the large profiles is made possible by the spring compression of the small tips. The bit with a 1/4" hexagon drive (Wera connection series 1) can also be used with e.g. bit ratchets and bitholding screwdrivers with Rapidaptor. The 9504 tyre jack has a 1/4" mounting for using a 1/4" bit. When both 9504 tyre jacks are stacked together, a 4-in-1 bit can be inserted and you get a screwdriving tool. The 9505 tyre jack serves as both valve ejector and bleeder valve. The jacks and 4-in-1 bits can be clipped together, so that everything is compact and nothing will be lost.
