L-TWOO’s new hydraulic groupsets are incredible value, but how do they stand up to long term use?

So i’ve been using the L-TWOO RX 2x12 speed carbon groupset on my road bike for the last 6 months, and I've clocked up just over 2000km. I bought it from AliExpress, and compared to the mainstream options like Shimano 105 or Ultegra, it is VERY competitive in terms of price, but should you consider it?
The groupset was very easy to install, and It has been performing really well overall. The braking performance of the hydraulic disc brakes has been incredible, and the hoods are also very comfortable.
However it’s not perfect, and there are a couple of things worth delving into. The shifting performance, while good, does need some tweaking. The calipers have corroded slightly, and the shifters did initially rattle. BUT I still think it is an incredible option for a budget carbon road bike in 2023.
In this episode, I’ll give you a rundown of the groupset, demonstrate you what to look out for, and show you why it has impressed me so much!

Créé le : 24 mars 2026Le critique a testé le groupe de freinage hydraulique à disque L-TWOO RX 12 Disc 2x12s en carbone pour route pendant six mois et 1200 miles. Il a constaté qu'il offrait un excellent rapport qualité-prix, avec une installation facile, d'excellentes performances de freinage et un bon changement de vitesse dans l'ensemble, mais a noté certains problèmes de sensibilité de l'indexation à 12 vitesses, une légère corrosion sur certaines pièces et un risque de casse des leviers en carbone. Il recommande la version 11 vitesses pour une meilleure fiabilité et un meilleur rapport coût-efficacité.
Résumé IA
Pros
- Facile à installer avec des durites pré-remplies et un processus de purge simple.
- Excellente performance de freinage, comparable au Shimano Ultegra Di2.
- Bonnes poignées en caoutchouc qui ne s'étirent pas et ne se desserrent pas.

Cons
- L'indexation à 12 vitesses est très sensible ; de légers changements de tension du câble peuvent provoquer des problèmes de changement de vitesse.
- Le passage des vitesses sur les petits pignons (vitesses supérieures) est moins fiable et moins réactif.
- Légère corrosion sur les écrous et boulons de serrage des étriers de frein, éventuellement due au sel de voirie.
