The German HASE is known for its focus on disabled cyclists. In fact, all the products that this company produces are usable for people whose mobility is somehow limited. It is no different with their latest novelty, which, however, easily finds application even among individuals who have been more fortunate in their lives and are not limited in any way.
These are cranks adjustable in the range from 65 to 165 mm, while you do not need any tools to change the length. The cranks are designed for both square taper and Hollowtech standard, so it is possible to use them on almost all types of recumbent bikes, including those with a Shimano Steps e-assist.
Let me tell you that the price is 350 EUR / 452 USD.
