Azub trikes are adventure ready

Azub will be at AlphaBENT on Wednesday, October 23 to show the latest Czech recumbent technology. Come to for test-rides, and bent-talk.

Catrike has made wider hubs with through-axles standard equipment on all large-wheel models. This change affects the following recumbent trike models: Expedition, 559, Dumont, and 700. The change promotes laterally stronger wheels and prevents movement within the dropouts under load at the expense of compatibility with equipment such as electric hub moters that are designed to the older 135mm dropout widths.
