SRAM X0 Type 2 Rear Derailleur (2013)


Recently, I had the chance of testing SRAM’s new concept regarding rear derailleurs. Type 2 is mainly the reply to Shimano’s Shadow Plus technology, being able to perform the same tasks. Only in this case, the functioning principle is different.

The new SRAM X0 Type 2 looks nice, with fine contrasts and pleasant touches of colour, even glossy here and there. Exactly how the other high-end products of the American manufacturer present themselves. But in this situation, we mustn’t forget that appereance without performance doesn’t stand for much, so that is why the SRAM X0 Type nedeed to pass the baptism of fire.

So, what’s it all about?

When I reffer to the X0, I must underline the two technologies used: Roller Bearing Clutch and Cage Lock. The first, truthful to its name, works like a clutch, keeping steady the position of the derailleur and diminshing chain slap when crossing over sturdy bumps. Basicly, the chain doesn’t hit neither the top, nor the bottom of the chainstay. The manufacturer says this feat is achieved thanks to a nail bearing that tensions the chain, but it doesn’t offer any insights in how the mechanism actually looks. The bottom line still stand though, and what is for certain is that bumpy trails will no longer be able to make the chain jump around. The key difference between the Shadow Plus and the Type 2 is that the latter doesn’t have the On/Off switch as the first does.

Cage Lock is an at least interesting piece of innovation, which makes wheel-removing problems a thing of the past. You only need to flip a switch for the pulley to get perpendicular to the ground. After this, taking out your rear wheel is as easy as pie. If you forget to turn the Cage Lock off, you will be spared of trouble, as SRAM designed the mechanism to deactivate as soon as it detects any shock.

As far as shifting performance goes, Type 2 has a slight edge over Shadow Plus, but then again, I believe it to be much too small for a lot of people to notice it. Sliding over the 10 cogs of the cassette is a task much too easy for the SRAM X0 Type 2, shift speed and accuracy living up to their expectations. Shifting under load doesn’t put the derailleur in a difficult situation either, although the chain may be heard more clearly when switching to lower gears and this action may speed up the wear of the drivetrain.

As a final conclusion, I recommend you the SRAM X0 Type 2. If the price tag looks to be a bit high, you can wait for the technology to be present in lower groupsets or you can go for a X9 derailleur fitted with the Type 2 system. Reaching expected performance, not being overweight, and without any unpleasant chain-noises, SRAM X0 Type 2 raises the bar when it comes to rear derailleurs, especially given the short, medium or long cage options.
