SANDBLOCK® is het officiële door Marwi geregistreerde beeldmerk van een beschermde samenstelling van materialen dat een duurzame perfecte anti-slip inzet vormt voor pedalen. De antislipwerking van het materiaal is gegarandeerd, ook wanneer het nat van besmeurd is met olie of vet. Deze antislip-inzet is door een speciale, watervaste technologie niet van het pedaal te scheiden.


De UNION SANDBLOCK® pedalen hebben een extra grote anti-slip inzet (dus meer direct contact met de schoen van de fietser) en zijn speciaal ontworpen voor de toepassing op E-Bikes.


De voordelen van deze hoogwaardige SANDBLOCK® antislip inzet zijn:

  • Een zeer goede antislipfunctie, veel beter dan de gebruikelijke TPR (rubber) inzet
  • Belangrijk meer slijtvastheid vergeleken met de van de conventionele TPR (rubber) inzet
  • De antislipfunctie blijft optimaal, zelfs wanneer de oppervlakte van het materiaal nat of besmeurd is met olie of vet

De SANDBLOCK® antislipvlakken zijn zeer slijtvast, waterbestendig en stevig verbonden met het robuuste polypropyleen van het pedaal via een nieuwe gepatenteerde kooie-technologie. Vergeleken met de zelfklevende schuurpapier versies van pedalen die worden gebruikt, is deze sterke verbinding watervast en niet te scheiden of verwijderen van het pedaal.


Technische details en testresultaten:

  • Diverse laboratoriumtesten bewijzen dat het SANDBLOCK® niet gescheiden of verwijderd kan worden van de kooi van het pedaal, zelfs niet wanneer hiervoor gereedschap wordt gebruikt
  • De antislipfunctie van het SANDBLOCK® heeft veel betere prestaties dan het standaard antislipmateriaal dat is gemaakt van schuurpapier
  • Een antislip duurzaamheidstest laat zien dat met een belasting van 30 kg en bij 10.000 cycli, het materiaal slechts 0,25 mm afslijt
  • Bij een inzet van standaard schuurpapier toont dit al slijtagesporen na 20 cycli. SANDBLOCK® doet dit niet
  • De inzet van standaard schuurpapier laat zich heel gemakkelijk scheiden van de polypropyleen kooi van het pedaal. Bij SANDBLOCK® gebeurt dit niet

Door het SANDBLOCK® materiaal te passen in plaats van TPR of standaard schuurpapier wordt met deze UNION pedalen een nog hogere mate van veiligheid voor de fietser bereikt in alle weersomstandigheden.

An Extinct Breed - Get before they are gone
Size: Medium, Color: Red
In my day polos used to be soft thick 100 % cotton with generous sleeves covering the upper arm till above the elbows and collars standing high and grand and covering the back of the neck till below the hairline. They had substantial structure/body (shape that held) and ultra comfortable soft cotton. This was my go to piece of clothing to step out in (as opposed to round neck collarless T-Shirts that I wore only at home or for sporting activities). However, this simple good thing was not to be taken for granted. As time went by, I watched in horror this simple evergreen staple slowly vanish - being replaced by plastic, toxic, carcinogenic trash (synthetic, polyester, 'performance', 'hi-tech') being passed as clothing riding solely on deceptive/misleading/convincing marketing and rapidly transient 'fast fashion trends'. These pieces of junk being passed as 'performance polos'/'hi-tech' had no 'body', clung to your skin like plastic, caused my sensitive skin to itch, with arms so short as if there was shortage of clothing material in the world and were of such thin cheap uncomfortable material that I would wonder how in the world do people put these on their bodies. The 'trend' continued ... Fast forward to the present day, finding the 'cotton polo of my youth' is like finding a dinosaur. The polo I grew up with is practically extinct - replaced by trash made with ever cheaper feeling and more toxic materials. Its a win win for the corporates/brands - cheap synthetic lab created materials astronomically marked up (riding on advertisement) - filling the corporate pockets unlike never before and successfully 're-programming' the minds and purchasing behavior of the new generation to accept, get used to, and even get addicted to such toxic 'hi-tech' trash. As for the manufacturing ? No problem - hire some MBA's (with zero knowledge/passion for good quality textile/garment manufacturing) - their sole purpose to be 'maximizing profits' for the next 'earnings report' and they would find the 'cheapest' offshore factory to outsource the manufacturing to. This being a continuous process - if you get a cheaper bid from another factory, just switch to it. No wonder you can never get consistent material, sizing, quality for the exact same product purchased even months apart. Not just that - even brands that sold fantastic quality 100 % cotton polos at a very reasonable price like Tommy Hilfiger etc went STEEP DOWNHILL. A Tommy Hilfiger polo being sold today is NOWHERE NEAR anything like the quality they had even a few years ago (even though still being theoritically 100 % cotton, the quality (material, cut) now is absolutely junk - in fact they went from being my favorite Polo Shirts (thick, soft, cloud like cotton with generous neck and sleeves and amazing body, texture and shape and in high quality colors and finish) to absolutely shockingly unwearable pieces of garbage (thin, rough, itchy cotton with skimpy sleeves and flat collars and dull cheap finsih and colors with NO lusture, body whatsoever). I always wish I had seen this day come. I would have stocked up on a lifetim's supply of 'real' clothing when they were still available. Given the above, I am extremely surprised (pleasantly) by this Amazon Essentials Cotton Polo. This is 100 % cotton, has generous non-skimpy sleeves and has decent material and shape reminiscent of the 100 % cotton polo I am habituated to from my time. Quality of material wise - it is about 65% - 70% of the cotton polos of yesteryears - BUT - even THAT - is like finding diamond (or a dinosaur) in these abhorrent-clothing-times for the 100 % cotton polo lover. Get this before the 'real cotton polo' is gone for good. I think I may be getting a few.

Sometimes Good, Sometimes Not So Good...
Size: X-Large, Color: Aqua
I've bought several of these shirts in the past, and I've always been very happy with them, right up until my latest purchase. Apparently, depending on which color/style you choose, the shirts may be manufactured in a completely different country. And despite Amazon's efforts to make sure their clothing brands have consistent sizing across the board, it's now clear to me that some of those countries are not on the same page. Case in point: Guatemala. My latest Amazon Essentials polo shirt purchases consisted of the colors 'light yellow' and 'rust'. Now, the light yellow shirt seems fine. Maybe a tiny bit smaller than my previous shirt purchases, but nothing major. (I think it says made in Chihuahua - but it's hard to tell.) However, the rust colored shirt is drastically smaller than all my similar-sized Amazon polo shirts. I bought it in size Large, but the shirt tail alone is nearly four inches shorter than my previously purchased Amazon Essentials polo shirts. And while the Large-sized Amazon polo shirts normally fit me quite comfortably, with a little bit of room to spare, this rust-colored shirt is skin-tight. If I didn't know any better, I'd swear it was a size Medium masquerading as Large. All of my previous shirt purchases (I now realize) are labeled as being made in either Madagascar or Vietnam. Those are great. They fit wonderfully. But this new rust-colored shirt (once again, same brand - Amazon Essentials) is labeled as made in Guatemala. And let me tell you, the factory in Guatemala is not on the same page as the factory in Madagascar. Not even close. So yeah, these are great shirts. So long as you happen to buy the colors/styles that are being made in Madagascar or Vietnam. But buyer beware if you happen to get one from the factory in Guatemala, because those guys are using a whole different set of rulers over there. And unfortunately, there's no way to tell until it arrives on your doorstep. I'm normally a big fan of Amazon brand products. But this experience has made me quite a bit more wary about buying their clothing items in the future. It really is so very important that their brands have consistent sizing across all colors and styles. P.S. I actually bought the rust-colored shirt TWICE, because I at first assumed I must have gotten a mislabeled product. But, nope. Both rust-colored shirts are the same, drastically-smaller size, and both are labeled made in Guatemala.
