This New Chinese Groupset Is Legitimately Fantastic

Descripción

The new L-TWOO R9 Pro is easily the best mechanical groupset out of China I have EVER tested. It costs just £123 from AliExpress, but after riding it back-to-back with Shimano 105, the actual shifting and braking performance is INCREDIBLY close.

In this episode, I'll take a detailed look at the latest L-TWOO R9 Pro, a 2x11 speed mechanical groupset with hydraulic disc brakes. I'll be installing the complete groupset, looking at the shifters, the front and rear derailleurs, and the brake calipers, before putting everything through its paces out on the road.

I've been using the previous generation L-TWOO R9 Disc for around two years, and I've put roughly 6–7,000 miles through it. That groupset was already fantastic, but the new R9 Pro is a major re-design. The shifters now operate much more like Shimano, the rear derailleur has been completely redesigned, installation is easier, and the overall build quality has taken a noticeable step forward.

But the big question is performance. To find out just how good it really is, I rode it back-to-back with the latest Shimano 105 R7120 12-speed mechanical groupset, and I also swap my lightweight ZTTO cassette for a Shimano Ultegra Hyperglide cassette to see just how much difference the cassette makes.

Of course, it's not perfect. There are still a few areas where Shimano's extra refinement shows, including shifter feel, ergonomics, the front derailleur design, and the brake bleeding process. I also look at a couple of quirks with the L-TWOO shifters and discuss just how similar some elements of this new generation are to existing Shimano components.

All in all, if you're building a budget road bike, looking for a Shimano 105 alternative, or you're simply curious about how far Chinese groupsets have come, this is a SERIOUSLY interesting piece of cycling tech.

As always, I bought the groupset myself with my own money, and everything in this video is based on my own experience using it.

LTWOO R9 Pro 2x11s Road Hydraulic Disc Brake Groupset (2026)

LTWOO R9 Pro 2x11s Road Hydraulic Disc Brake Groupset (2026)

Creado: 9 de septiembre de 2026

El reseñador, Luke de Trace Velo, analiza el grupo de freno de disco hidráulico para carretera LTWOO R9 Pro 2x11s (2026) como un grupo de nueva generación que compró por 123 £ en AliExpress. Señala que cambia como Shimano, tiene una calidad de construcción impresionante y rinde muy cerca del equipo Shimano a una fracción del coste. Lo instaló en su bicicleta, sustituyendo el grupo R9 más antiguo, y encontró la instalación sencilla, aunque menciona un problema menor con la sustitución del cable de cambio.

Resumen IA

Pros

  • Increíblemente barato a 123 £
  • Cambia como Shimano (reduce con toda la maneta de freno, sube con la palanca más pequeña detrás)
  • La calidad de construcción es realmente impresionante

más pros en el vídeo

Cons

  • El desviador delantero no tiene nada de especial, es bastante básico e idéntico a la generación anterior
  • Ligeramente más pesado que el equivalente de Shimano (1.299 g frente a unos 1.260 g)
  • Para sustituir un cable de cambio, hay que bajar ligeramente la goma de las manetas para acceder al puerto, lo cual no es fácil con los mandos instalados; puede que haya que soltar el tornillo de fijación y separar el mando
