L'esperienza ultrafluida della gamma ULTEGRA R8100 a 12 velocità ti permette di superare salite, sprintare e fare lunghe percorrenze senza fermarti a pensare al prossimo cambio marcia. I pignoni più grandi massimizzano l'efficienza del sistema di trasmissione e creano la compatibilità con i corpi mozzo SHIMANO 11 e 12v.

Le cassette HYPERGLIDE+ hanno rivoluzionato il cambio nel fuoristrada con una perfetta fluidità di cambiata e scalata. È arrivato il momento dei cambiamenti tecnologici per il ciclismo su strada. Anche durante gli sforzi massimi in salita o facendo a gara con un amico, non è più necessario ridurre la pressione sui pedali per cambiare marcia. In qualsiasi marcia, le trasmissioni ULTEGRA R8150 massimizzano l'efficienza grazie a pignoni più grandi e mantengono la compatibilità con i corpi dei mozzi posteriori HYPERGLIDE esistenti. Tutto questo passando a 12 marce e senza aumentare il peso, le cassette ULTEGRA CS-R8100 sono la nuova frontiera per le bici da strada.

CARATTERISTICHE

  • La raffinata progressività 12 step massimizza efficienza e prestazioni in accelerazione per tutte le situazioni in gara
  • Cambio rapporti più veloce e fluido anche con forza di pedalata massima
  • Compatibile con il nuovo corpo mozzo posteriore 12v e da strada 11v

    Good performance, flaky Wi-Fi connection
    Style: L50 SES
    The L50 physically works great - it does a good job of picking up dust and dirt at the end of the day. The pathfinder and route planning algorithm is fairly efficient at determining the best way to clean a room. Sometimes it kicks around bits of dust with its spinning brush without picking it up, but it's not often. What has been terrible, however, is the Wi-Fi support. Since our provider disabled 2.4 GHz support from their router modem without notice, I use a Mac Mini to supply the 2.4 GHz signal, and even though the Eufy is next to it and my phone gets full signal strength, it still can't connect to it half the time. After it fails to connect, it needs to be restarted or even reset to try to get the connection again. Support doesn't seem to be helpful in offering a solution.

    Perfect Replacement Roller Mop for Eufy Robot Vacuum
    This replacement roller mop fits perfectly and works just like the original. Installation was quick and easy, and the quality feels durable and well-made. It does an excellent job picking up dust and light debris while providing consistent floor cleaning performance. The roller is washable, easy to maintain, and holds up well after multiple cleaning cycles. I appreciate that it restores the robot’s cleaning effectiveness without any compatibility issues. If you own a compatible Eufy model and need a replacement, this is a reliable option that keeps your robot performing at its best. Highly recommended for maintaining optimal cleaning results.

    Not good, poor quality from Eufy products
    I bought this as a last try to fix my unit. I wanted to share my experience with the Eufy S1 Pro after owning two units. Unfortunately, both units had serious issues. The first one developed multiple problems within less than a year: Dirty water tank issues Mop roller lifting motor malfunction Loud and abnormal noise during dust collection Eventually stopped working completely Despite that, I decided to give it another try and purchased a second unit, planning to reuse parts from the first one if needed. However, the second unit failed even faster. After around 2 months, it stopped performing dust suction from the robot to the base station. At this point, I cannot recommend this product. The reliability has been very poor in my experience, especially considering the price. On a positive note, customer support has been responsive and helpful, but unfortunately, the product quality itself did not meet expectations.
