Gravel- und Touring-Lenker Randonneur ER-20 Ergotec 513 oder 553 mm

Der Randonneur ER-20 Lenker von Ergotec wurde speziell für den Einsatz im Gravel-, Touring- oder Adventure-Bereich entwickelt. Seine dynamische Form garantiert ein einzigartiges Fahrgefühl sowie stabile und zugleich wendige Kontrolle. Ideal für Radfahrer, die viele Kilometer am Stück zurücklegen. Er bietet zudem die Möglichkeit, zwischen mehreren Handpositionen zu wählen. 

Dieses Gravel-Lenker-Modell unterscheidet sich vom einfachen Ergotec Randonneur Lenker vor allem durch seine größere Breite (zwei Modelle zur Auswahl, beim Kauf auswählbar):

  • Das Modell 513 mm: hat eine Gesamtbreite von 513 mm und eine Achs-zu-Achs-Breite von 420 mm
  • Das Modell 553 mm: hat eine Gesamtbreite von 553 mm und eine Achs-zu-Achs-Breite von 440 mm

Außerdem durch:

  • Seinen Rise von 20 mm: das ist die Erhöhung des Lenkers im Vergleich zum Befestigungspunkt am Vorbau (siehe Foto)
  • Sein geringeres Gewicht von nur 332 Gramm

Technische Daten des Ergotec Randonneur ER-20 Lenkers

Hier die genaueren Maße des Gravel-Lenkers Randonneur ER-20 von Ergotec (siehe Fotos), die für eine bessere Griffigkeit sorgen und damit für mehr Komfort und Sicherheit beim Fahren: 

  • Reach von 75 mm: der Lenker ragt 75 mm über den Befestigungspunkt hinaus
  • Flare von 16°: das ist der Winkel (nach außen) der Lenkerenden im Verhältnis zur Vertikalen 
  • Drop von 125 mm: das ist der Höhenunterschied zwischen der höchsten und der niedrigsten Lenkerachse

Die Fertigung ist wie gewohnt robust aus Aluminium 6061 T6, in schwarzer Ausführung.

Mit einem kompakteren Profil, ausgelegt für noch längere Fahrten, bieten wir auch den Ergotec Gravel Lenker an, der einen stärkeren Flare von 21° und einen geringeren Drop von 110 mm besitzt.

Wie montiert man einen Fahrradlenker mit 31,8 mm Durchmesser?

Der Randonneur ER-20 Ergotec Lenker hat einen Durchmesser von 31,8 mm in der Mitte. Er ist somit für die Montage mit einem 31,8 mm kompatiblen Vorbau vorgesehen. Die Montage ist sehr einfach: Lösen Sie die Klemmschelle des Vorbaus mit einem Inbusschlüssel, setzen Sie den Lenker ein, positionieren Sie ihn mithilfe der Markierungen und ziehen Sie die Schelle wieder fest.

Um Ihren Randonneur ER-20 für mehr Komfort und Sicherheit auszustatten, finden Sie bei uns Lenkerbänder sowie Frontbeleuchtung für den Lenker.

Und für Ihre Touren entdecken Sie unsere Gravel-Reifen 650B und Gravel-Reifen 700 sowie den Gel-Sattel für elektrische Gravel-Bikes E-Sport SMP.

Great chair, only one issue.
Number of Items: 1
As someone who is exactly 6ft tall, this chair is just about perfect for my height and body type. High quality materials, adjustable lumbar support, very ergonomic. Visually, it works well with my desk setup. It has already helped me improve my posture ten-fold. My only complaint might be that the tension on the recline joint is too much. Twisting it to the loosest setting doesn’t feel loose enough, you’ll need to put your feet up on something to recline comfortably and stay in that position. Other than that, great chair. I don’t see myself returning this one.

Get this chair if it is on sale for $100 or less!
Number of Items: 1
I am a 180lb, 5'8" tall male. I needed an office chair that would support and cover my entire back, shoulders, and neck, while locking at 90° upright, and allow me to sit with my hips over knees (slightly) with my feet flat on the floor. I also needed the arms of the chair to support my arms and shoulders in a neutral resting position, as well as move up and out of the way. This chair did all of that for just over $100 and next day delivery. I'm happy with it and will be keeping it long term. Build time was 20 minutes. All needed tools and materials were included. Instructions were clear and easy to follow. Components appear to be properly made, well fitting, and durable. Everything works properly. The arms are the proper height for me. The seat cushion and lumbar curve are good. The wheels fit through doorways just enough. The seat height can be set both adequately low and high for my height and needs. The tilt sensitivity is adjustable via a knob under the seat. The position lock works properly in the upright position. The only cons for me: Position lock is not available in recline. The neck support is not padded enough and uncomfortable to rest your neck against for long. The neck support mechanism cannot extend closer to or further away from the back of your neck. It can only be moved higher or lower. The mechanism can also be tilted up or down to change its angle. This chair is worth the $100 I paid.

Comfortable chair that works great for long hours
Color: Black
I’ve been using this office chair for a few days and it’s been very comfortable for working and longer desk sessions. The high back design and ergonomic support help maintain good posture, while the cushioning stays comfortable throughout the day. The chair feels sturdy and stable, and the 330 lb capacity gives it a solid, durable feel. It also rolls smoothly and quietly, which is nice when moving around the workspace without creating a lot of noise. Overall, it was easy to assemble, looks professional, and offers great value for the money.

Very Comfortable Ergonomic Chair - Great for Long Work Days!
Color: Black, Color: Black
I’ve been using this ergonomic office chair for a couple of weeks now and I’m genuinely impressed. For the price, it offers excellent comfort and support. What I like: • Very comfortable padded seat and backrest — I can sit for 8+ hours without back pain. • Good lumbar support and adjustable height/armrests. • Holds up to 330 lbs easily (I’m 240 lbs and it feels very stable). • Smooth rolling wheels and sturdy base. • Easy to assemble (took about 20 minutes). The mesh back breathes well and doesn’t get hot. It looks professional in my home office too. Overall, this is a solid ergonomic chair. If you spend a lot of time at a desk, I highly recommend it. Would I buy it again? Yes, definitely.
