Steel and plastic. These are the basic ingredients Shimano Tourney TX derailleur is made of. Even if it belongs to Shimano’s entry level range, there is no need to panic. It may seem hard to believe, but there is another version of this derailleur, placed even lower in Shimano’s range, the Tourney TZ.
Tourney TX has been designed for cheap and very cheap bicycles and it has suffered a few changes lately, which also relate to its look. Under the premise that this is a budget derailleur, offered for approximately 10 euro only, we’ll try to analyze its performance and offer more details in this article.
Tourney TX works with 6 or 7 speed cassettes. It is not a fast derailleur but rather a slow and noisy one, even if you don’t shift gears under load. One can relatively adjust it rather quickly, the two screws being at hand. After longer periods of use, the derailleur needs small adjustments in order to function correctly.
The materials it’s made from belong to the entry level range. As a result, the derailleur body is no stranger to plastic, while the cage and the hanger bolt are made of steel. These materials make Tourney gain a lot of weight, hitting a real record value, of 355 grams, as the average is somewhere around 240 grams. But, if you start thinking how much this derailleur costs, then you simply stop being critic. However, on holistic approach of the entire bike, the extra-weight makes itself present.
The derailleur is compatible with Shimano’s Mega Range sprocket, which counts no less than 34 teeth, in order to diminish rider’s effort on very steep inclines. Even so, the Mega Range concept (in its 11-13-15-17-20-23-26-34 configuration) did not manage to make it out of the entry-level segment, and make an impression in another component range. This is because it’s quite questionable how useful a sprocket with so many teeth really is in a class where bicycles are used for recreational riding. However, Tourney TX has been designed to cope with this sprocket.
To reduce rider’s effort when shifting gears, Shimano has installed a wheel type cable guide. This is installed under the derailleur’s body, offering a clean cable routing.
In terms of cost, you could be tempted to say this is a good buy. However, if your bike is not fitted with a 6 or 7 seven speed sprocket, we advise you to look towards Alivio, even an older model, which can still be found in some shops. It’s slightly lighter, and those 20 euro you’ll have to pay are not a significant amount. Else, Shimano Tourney TX is a good choice for old type cassettes, yet far from being brilliant.
