Rohloff offers a version of our now legendary SPEEDHUB 500/14 gear hub especially suited to the extreme conditions in which Fatbikes are used. The Rohloff SPEEDHUB 500/14 XL is constructed for frames using a 170mm spacing and dropouts which accept 10mm threaded or quick-release axles (not thru-axle compatible).

Fatbikes are primarily designed to enable one to keep pedalling through even the harshest conditions - conditions in which a cyclist on a traditional bicycle would be forced to dismount and push. The fat tires offer a much larger footprint thus keeping the bicycle afloat on soft terrain. The additional traction this provides ensures a Fatbike rider will enjoy many miles of riding long after the standard bicycle has reached its limits. Fatbikes are especially suitable for transversing snow, bogs/marshland and sand.

The SPEEDHUB 500/14 XL is the ideal transmission for Fatbikes. The conditions in which such bicycles are ridden require a transmission that can be kept as clean as possible. Only a clean, un-clogged transmission can ensure problem-free functionality and nothing increases the enjoyment you can have out on the trails more than having access to the right gear at all times! Of course the SPEEDHUB 500/14 XL has the additional advantage of being compatible with the ‘Gates Carbon Drive’ belt drive system, reducing the level of transmission maintenance even further.


Further advantages:

  • 14 real gears
  • Even gear increments of 13.6%
  • 526% overall transmission ratio
  • Straight chain-/belt-line
  • Incredibly strong rear wheel due to even spoke tension
  • Encapsulated construction
  • 100% adjustment free
  • Extremely low maintenance
  • Compatible with the 'Gates Carbon Drive' belt drive system.

These dimensions enable the use of up to 5" tires (mounted on rims up to 100mm wide) in frames with a 170mm spacing - without the risk of chain/tire interference! We recommend the use of rims with a minimum 12.5mm nipple offset in order to avoid the spoke 'kinking' when entering the nipple. Such kinks will weaken the spoke and can cause premature spoke failure.

We regret that it is not possible to convert existing SPEEDHUB 500/14s (135mm, 142mm, 148mm) to the XL (170mm) format!
