FORM MTB Extra Height Stacker – Solution for Significant Limb Length Differences (LLD)
The FORM Extra Height Stacker Kit is a specialized modular solution designed to extend the compensation range of the MTB V2 system beyond the standard 3-6mm. It's ideal for cyclists who require stable and secure support with significant anatomical imbalances.
Important note: This product is an expansion kit and does not include the MTB V2 base system – it requires separate purchase.
COMPENSATION CONFIGURATION AND RANGE
The system offers two variants of sets that, when combined with the MTB V2 base system:
| Set | Total Liability Deduction (LLD) |
|---|---|
| Variant 1 (4/6 mm) | 7mm – 10mm |
| Variant 2 (+8/10 mm) | 11mm – 14mm |
TECHNICAL AND BIOMECHANICAL ADVANTAGES
- Easy Engagement: The specially angled (beveled) front of the pads makes it drastically easier to hit the pedal with the cleat, which is a key issue when using high spacers.
- Tough Glass Filled Nylon Material: The use of glass-filled nylon provides extreme stiffness and impact resistance, eliminating material deflection under heavy loads.
- Modular Clip-on System: Allows for precise height adjustment without having to completely disassemble the block.
SHOE REQUIREMENTS
Due to the dimensions necessary to ensure full stability with a large number of pads, this system requires an appropriate sole surface:
- A "clean", flat surface from front to back of the sole is required, free from protruding rubber tread blocks.
- In the case of rubber lugs, there are ways to work around the problem, but a flat sole is the optimal solution.
