Die neue FC-R8100 Kurbel der ULTEGRA Reihe bietet die gleiche schnelle, präzise Schaltleistung vorne und dieselbe effiziente Kraftübertragung, für die SHIMANO bekannt ist. Darüber hinaus steht sie in noch mehr Längenvarianten zur Verfügung als bisher. Mit einer Länge zwischen 160 und 175 mm eignen sich die ULTEGRA Kurbeln nun auch für kleinere Fahrerinnen und Fahrer, Triathleten und alle, die sich für kürzere Kurbelarme interessieren.

HOLLOWTECH
Leichte Kurbeln reduzieren das Gesamtgewicht des Rades und vor allem die für die Beschleunigung entscheidende rotierende Masse. Die Herausforderung besteht darin, das Gewicht der Kurbel zu senken, ohne Stabilität und Belastbarkeit zu beeinträchtigen.
SHIMANOs hochmoderne Schmiedetechnologie bietet mit der HOLLOWTECH Kurbel eine ideale Lösung. Genau wie ein hochwertiges Rahmenrohr ist die Hohlarmkurbel bei sehr geringem Gewicht enorm stabil und belastbar.

HOLLOWTECH II
Zusätzlich zu den Vorteilen der HOLLOWTECH Technologie, ist bei der HOLLOWTECH II Garnitur die rechte Kurbel fest mit der Achse des Innenlagers verbunden, wodurch eine optimale Ausgewogenheit zwischen höchster Steifigkeit und geringstem Gewicht erzielt wird. Das außen gelagerte Innenlager bietet eine bessere Gewichtsverteilung und mehr Stabilität, was für eine effizientere Kraftübertragung sorgt. Bei der Entwicklung der HOLLOWTECH II Kurbelgarnitur wurde Wert auf ein optimales Verhältnis zwischen Steifigkeit und Rotations-effizienz sowie geringem Gewicht und attraktiver Optik gelegt.

Die HOLLOWTECH II Kurbelgarnitur verfügt darüber hinaus über hochwertige Präzisionsdichtungen im Lagerbereich, um die Haltbarkeit zu verlängern und die ausgezeichnete Rotationseffizienz langfristig zu erhalten.

Great shoes
Size: 10.5, Color: Dark Grey
I saw people wearing shoes like this in the office (maybe not the same brand), so I ordered a pair to see how they feel. They feel amazing. It's basically sneaker that look ok to be worn with pants and sport jacket. Fit is great, I ordered my usual size and they fit nicely. Sole is thick enough to make them comfortable, not too thick to looks like a sport sneaker. Durability seems ok, wore them couple of times, so I can't really tell, but they seems like they can last long time.

Love these shoes
Size: 9.5, Color: Grey
These shoes are soft, comfy, and easy on and off. They breathe in the summer heat and feel good on a cool evening. They run true to size and the colors are like they are represented. I recommend this brand for a good looking, inexpensive shoe.

Comfortable shoes that still look presentable
Size: 12, Color: Black
I wanted a pair of shoes that were more presentable than regular sneakers but did not feel like stiff dress shoes, and these fit that role well. They have the look of a casual oxford, but the mesh upper makes them feel much lighter and easier to wear. That makes them useful for days when I want to look a little more put-together without sacrificing comfort. They are breathable, easy to walk around in, and work well with casual outfits. The only thing I’d keep in mind is that the mesh material can take a little extra care to keep clean, but that is a reasonable tradeoff for the comfort.

Summertime Comfort
Size: 6.5, Color: Light/Brown
My husband has a small foot and the shoe was a perfect fit for him, size 6 1/2. Normally this is a difficult size to find in a shoe. He was very pleased with the color and weight of the fabric. The fabric is breathable and lightweight. The shoes are very well constructed with a nice solid heel and sole. They are a perfect summertime shoe. The shoes will go well with shorts or casual trousers.

Comfort + Style = Dream Walkers
Size: 13, Color: Dark Black
Im in awe of how comfortable these are. Took a chance on this unfamiliar brand because the price and style were just what I was looking for. They came today tried them on, they are so light and airy and the super spongey soul make them dreamy to walk on. Now let's just hope they last 🤞🏼 Thanks for making a great shoe!
