Marwi Pedal Set SP-827 Sandblock® black

A bicycle pedal with a non-slip insert on both sides made of patented SANDBLOCK® material, a durable polypropylene axle housing, and a cage, specifically designed for use on electric bikes. It can also be used on city, trekking, and hybrid bikes.

• The "lightweight" ball bearing system provides significant savings in weight and height
• The pedals are equipped with integrated approved reflectors on both sides and a closed bearing system
• "2 component pedal", which consists of:
  • a black polypropylene axle housing and cage (one piece)
  • the extra large "anti-slip" insert in the cage is made of a gray TPE (thermo-plastic-elastomer)
• Adjustable and lightweight ball bearing system, according to the "ball & cone" principle, on both sides
• With 14 x 3/32" ball bearings on both sides
• Boron steel, heat treated to 75HRA (+/-3)
• With 9/16"- 20 TPI thread
• Integrated into the cage of the pedal
• Approved according to BS, JIS, TPP, as well as the German StVZO standards
• Dimensions:
  • 222* x 90 x 27 mm (*length x width x height)
  • *length = maximum length of pedal mounted (part that protrudes beyond the crankset)
• Weight:
  • 364 gr/per set
• Standardization:
  • The pedal complies with the ISO standard.
  • ISO 4210-8: "Bicycles - Safety requirements for bicycles - Pedal and crankset test methods"

SANDBLOCK® is Marwi's official registered trademark for a patented composition of materials that forms a wear-resistant, perfect anti-slip insert for pedals. The material's anti-slip properties are guaranteed, even when wet or stained with oil or grease. Thanks to a special, waterproof technology, this anti-slip insert is inseparable from the pedal.

The UNION SANDBLOCK® pedals have an extra-large anti-slip insert (therefore more direct contact with the cyclist's shoe) and are specially designed for use on e-bikes.

The advantages of this high-quality SANDBLOCK® anti-slip insert are:

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

The SANDBLOCK® anti-slip pads are highly wear-resistant, water-resistant, and firmly bonded to the pedal's robust polypropylene cage using a new, patented technology. Compared to the self-adhesive sandpaper versions of pedals used, this strong bond is waterproof and impossible to separate or remove from 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 using tools.
• The anti-slip function of the SANDBLOCK® has much better performance than the standard anti-slip material made of sandpaper
• An anti-slip durability test shows that with a load of 30 kg and at 10,000 cycles, the material wears off only 0.25 mm
• When using standard sandpaper, this already shows signs of wear after 20 cycles. SANDBLOCK® does not do this.
• The insert of standard sandpaper can be separated very easily from the pedal's polypropylene cage. This does not happen with SANDBLOCK®.

By using SANDBLOCK® material instead of TPR or standard sandpaper, these UNION pedals achieve an even higher level of safety for the cyclist in all weather conditions.
