Dirt jumpers, die hard single speeders, MTB fixers, biketrial riders, this is your hub. Innovative multi function construction allows for it to be used as a FIXED and FREE hub.
The HAUNEBU IV has super wide flanges (75mm) that will allow for you to build extra stiff wheels. We designed the hub so that you can fit the smallest freewheels available (down to 14T!) or put a Shimano cassette cog (down to 12t!) and use it as a fixie. FOUR double sealed bearings (two each side) located as close as possible to the frame dropouts minimize axle bending moment under the weight of the rider.
The CNC body with an International std. 6 bolt disc mount and four high quality sealed bearings will ensure smooth running for a long time. The screw on external axle is made on the highest grade 12.9 oxide coated steel, known as high tensile. The first number represents the ultimate tensile strength of the bolt, 12 x 100 = 1200 Mpa respectively. The second number represents the point at which the bolt will permanently stretch. (Officially, the 0.2% proof load stress). A 12,9 bolt permanently stretches at 90 %. Your axle has never been that strong.
The hub includes a cassette&lockring for fixed gear cogs (if you leave the cassete HG/UG body and lockring off, you can install singlespeed freewheels, for example DICTA BRAND).
