The continuously adjustable pedal crank

Yes, the WX-Vario is compatible with most standard cranks. Thanks to variable clamping jaws and the spacers supplied, it can be adjusted to different crank widths to ensure a secure fit.

In many cases, yes. Additional accessories are available for special requirements, including a 14 mm spacer for very narrow crank arms and a 1/2” central bolt for older or uncommon systems with corresponding pedal threads.

Please note: When using the 1/2” central bolt, a modern pedal with a 9/16” thread must be used for the sliding nut.

If you are unsure about compatibility, please contact us directly. With a few details or photos, compatibility can usually be clarified quickly. You can reach us at anfrage@wexelpunkt-wxvario.de.

Yes. However, your pedal should be able to be attached to the pedal axle with an external hexagon or open-end wrench. High-tech racing pedals that are only screwed in from the rear with an Allen key or Torx are unfortunately not compatible.

The WX-Vario uses the standard pedal thread (9/16 inch) to attach securely. A special screw provides support, while the clamping jaws and spacers are supported on the sides. This creates a stable and tested fit.

Not necessarily. If only one side is affected, a single adapter is sufficient. A double-sided set is particularly useful if there is a restriction on both sides or if a balanced load is desired.

Yes, all materials used are recyclable. The aluminum and stainless steel can be disposed of at the recycling center, and the plastic spacers are made of polyamide, which is also recyclable.

The conversion kit allows you to convert the WX-Vario from one side to the other at low cost. If you have initially used the adapter for the left side and later need it for the right side, you only need to replace the special central screw and the slotted nut. This saves resources and costs if your requirements change.

There is no fixed standard—every person is different. However, as a general rule, it is better to start off on the conservative side, i.e., shorter. This means that if you have only moderately limited knee or hip mobility, you could initially set the WX-Vario to about half and pedal for about a minute with very light resistance. You should not notice any evasive movements and should feel as little pain as possible – just a slight pulling sensation that does not increase during the test phase, but ideally even decreases. 

If you have more severely restricted knee or hip joints, it is best to start in the zero position, i.e., at the height of the bottom bracket axle, and test this first. In both variants, move forward gradually, after each test cycle, between 5 and 10 mm until you find the point where no evasive movements occur, but a slight pulling or gentle resistance is noticeable. This is then the ideal starting position.

Yes. As a general rule, the shorter the crank is set, the higher you can and should sit. This ensures a more ergonomic posture and a more even distribution of weight. Please note: With very asymmetrical crank lengths, the longer side always determines the seat height. This means that the seat height should be adjusted so that the leg on the longer crank side is not overextended in the lowest pedal position. This keeps the movement harmonious and easy on the joints.
