Roller or geared head kit

From the experience of Rollerball of wood and carbon by Alemanni a kit is born  Rollerball which allows you to transform your own crossbow commercial in one Roller.

Advantages :

• increase in potency  
• considerable increase in range 
• recoil reduction 
• accuracy and penetration

We assemble, on request, too ceramic bearings, very efficient, they become indispensable when you mount the inverter rubber.

With inverter rubbers as an alternative to ceramic bearings, you can mount kits with bushings (both are able to withstand large loads).

We do not recommend glass bearings for this set up.

Kit Roller is produced in three versions:

• Wheels on bushings - for all sizes - for tires up to 18 mm 
• Wheels on bearings – for all sizes – for tires up to 18 mm
• Rollers on ceramic bearings (high performance) - for all shotgun sizes - for tires up to 18 mm.

The kit includes the complete muzzle, a Ø 26 adapter, a stainless steel hook to build the loader, a threaded bar for the pre-tensioning cord.

Tires are not included. They can be had upon request.

You can request the built loader.
