TX-400

01

Origin

The TX-400 sits in VSF's expedition sub-range — bikes built specifically for long-distance world touring rather than commuting. Its defining choice is the 26-inch wheel, a deliberate decision for riders who travel through remote regions where 700c tires may be hard to find. The CrMo steel frame, Tubus racks, Magura HS33 hydraulic rim brakes, and Schwalbe Marathon Mondial tires combine into a machine that has crossed continents. It competes directly with the Surly Long Haul Trucker and Tout Terrain Outback — but made by hand in Germany.

The verdict

+Strengths
  • 26-inch wheels with Marathon Mondial tires are genuinely unmatched for loaded expedition resilience
  • Tubus racks and full front+rear pannier setup make it a complete four-corner touring rig out of the box
  • Magura HS33 hydraulic rim brakes deliver reliable wet-weather stopping with easily sourced consumables
Weaknesses
  • At ~16 kg it is heavy for day rides; optimised purely for loaded distance, not urban efficiency
  • 26" wheel size limits urban tyre variety in Western Europe compared to 700c
  • Rim brakes require clean rims — muddy roads reduce effectiveness more than disc setups
