Marwi pedal set SP-827 Sandblock® Black

A bicycle pedal with a "anti -slip" deployment of patented Sandblock® material, a durable polypropylene ashuis and cage, specially designed for use on electric bicycles. Can also be used on city, trekking and hybrid bikes.

• The "lightweight" ball bearing system gives a significant saving in weight and height
• The pedals are each provided on two sides with integrated approved reflectors and a closed lower system
• "2 components pedal", which consists of:
  • a black polypropylene ashuis and cage (from one piece)
  • The extra large "anti-slip" deployment in the cage is made of a gray tpe (thermo-plastic elastomer)
• Adjustable and lightweight ball bearing system, according to the "bullet & cone" principle, on both sides
• With 14 x 3/32 "Bulleted bullets on both sides
• Boron Staal, hardened by a heat treatment to 75hra (+/- 3)
• With 9/16 "- 20 TPI wire
• Integrated in the cage of the pedal
• Approved according to BS, JIS, TPP, as well as according to the German STVZO standards
• Dimensions:
  • 222* x 90 x 27 mm (* length x width x height)
  • *Length = Pedal length length mounted (share somewhat protruding outside the stair set)
• Weight:
  • 364 gr/per couple
• Standarding:
  • The pedal meets the ISO standards.
  • ISO 4210-8: "Bicycle security requirements for bicycle testing methods for pedal and stair set"

Sandblock® is the official logo registered by Marwi of a patented composition of materials that forms a wear-resistant perfect anti-slip for pedals. The anti-slip effect of the material is guaranteed, even when it is wet or smeared with oil or fat. This anti-slip deployment cannot be separated from the pedal by not a special, water-resistant technology.

The Union Sandblock® pedals have an extra large anti-slip deployment (so more direct contact with the cyclist's shoe) and are specially designed for the application on e-bikes.

The benefits of this high-quality Sandblock® anti-slip are:

• A very good anti-slip function, much better than that of the usual TPR (rubber) deployment
• Important more wear resistance compared to that of the usual TPR (rubber) deployment
• The anti-slip function remains optimal, even when the surface of the material is wet or smeared with oil or fat

The Sandblock® anti-slip surfaces are very durable, water-resistant and firmly connected to the robust polypropylene cage of the pedal through a new patented technology. Compared to the self -adhesive sandpaper versions of pedals that are used, this strong connection is waterproof and not to separate or remove the pedal.

Technical details and test results:

• Various laboratory tests prove that the Sandblock® cannot be separated or removed from the pedal cage, even when tools are used for this
• The anti-slip function of the Sandblock® has much better performance than the standard anti-slip material made from sandpaper
• An anti-slip Durability test shows that with a load of 30 kg and at 10,000 cycles, the material only wears 0.25 mm
• With a deployment of standard sandpaper, this already shows wear traces after 20 cycles. Sandblock® does not do this
• The use of standard sandpaper can easily be separated from the polypropylene cage from the pedal. This does not happen at Sandblock®

By applying the Sandblock® material instead of TPR or standard sandpaper, with these Union pedals an even higher degree of safety for the cyclist is achieved in all weather conditions.
