PL Lekkie rozczarowanie. Kółeczka przerzutki nienasmarowane. Jedyna opcja ich nasmarowania to wpuszczenie kropli rzadkiego oleju wazelinowego lub silikonowego na oś, ponieważ śrubek wózka nie da się odkręcić (zgiąłem dwa klucze imbusowe). Albo fabrycznie są zbyt mocno skręcone/zapieczone albo, co gorsza, śruby są jedynie imitacją, a tak naprawdę są to nity. W sumie na jedno wychodzi, bo gdy kółeczka się zużyją, nie będzie się dało ich wymienić. Z ich dokładnym czyszczeniem też będzie problem. No ale za cenę promocyjną nie ma co zbytnio wybrzydzać. Standardowej, cennikowej kwoty bym jednak nie dał. Plusem na pewno jest solidny aluminiowy korpus i mocna sprężyna. Założona do gravela zamiast uszkodzonego w kraksie Clarisa (8rz) działa równie dobrze, a może nawet lepiej.

The derailleur works in principle, and for systems of 7-8 gears basically without problems.
- from the beginning, the shifter has quite a big bull in his cap
- the pulleys are not lubricated, they run completely dry
- if you want to lubricate the rollers, you have to overcome the incredibly tight screws with thread sealant, while the screws are made of mud material = be careful of destroying the 3mm Allen hole
