Heavy Duty Fixed DISC HUB

Heavy duty Biketrial riders, this is your 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 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. 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).

Technical specs:
Color: RED Anodized
Hub Drilling: 32 and 36 holes
Rear Axle Type: Hex Bolts M10×1.25mm 12.9 class
Freewheel thread Type: Small M30xP1mm known as flip-flop
Cassette Body Type: Shimano HG/UG
Lock ring Tool: same as 8-notch Shimano XTR M950 and Truvativ ISIS Drive bottom bracket cups Tool
Hub/Brake Compatibility: 6-Bolt Disc
Rear Wheel Type: Mountain Rear Hub Spacing, OLD = 135mm (Outer Locknut Dimension)
Weight: 340g include bolts, washers, cassete, lock-ring

This absolutely gorgeous hub is the first 2in1 hub made to work with a freewheel and Shimano HG/UG cogs as a fixie.

Stealth HUB and other QR COMPATIBLE!!!

- The new 8.0's VERTICAL main feature is the rear dropouts, which are vertical with CS=379mm that 18:15 users can throw their wheel in without a derailleur and when the chain stretches using a 74kingz or whatever!
- Frame size is same this year in order to ensure clearance between brake cylinder and crank arms (fits 50mm wide rim), however the curve in the top tube ensures maximum clearance for extreme body positions.
- One piece CNC machined chainstay yoke and BB shell is super stiff, to ensure maximum pedalling response and good weld areas for all the tubes. 68mm BB shell width.
- Long gusset at the BB/down tube junction helps to resist dents when things go a little wrong!
- The 4bolts brake mounts are spaced to 100mm, to make sure even the widest of trials rims will fit.
- Frame construction is from high quality aluminium alloy, with a super classy painted.
