In our post introducing the new SRAM XX1 Black group, we reported that there were no mechanical changes to the group, only cosmetic. Some of our eagle-eyed readers noticed visible differences in some of the photos. Readers “zoso” and “steve” noticed that the pulleys looked different in the photo, lacking the “wide/narrow” tooth pattern and windows in the pulleys of the original.
We followed up with SRAM to see if they had made running changes to the derailleur. Duncan Riffle, SRAM MTB PR guy told us that the photos were incorrect in the launch, and re-issued the proper photo to us, shown above.
UPDATE: Some readers also noted that the mounting bolt appeared to be an allen key. Riffle said “the mounting bolt is a T-25 actually. The pictured image has a previous version used in older style XX1 Red (5mm Allen). It can be confirmed that new XX1 Black will have a T-25 just like XX1 Red.”
So while the photos may not be entirely correct, SRAM is stating again that there are no mechanical changes to the Black products over the red colored XX1 line.
UPDATE: Readers also noticing the “Type 2.1″ inscribed on the clutch, so we asked Riffle about that as well. “Regarding the Type 2.1 clutch, this is a simple running change implemented last year actually. Since the introduction of our Type 2 rear derailleurs with Roller Bearing Clutches, we have made numerous improvements and small refinements. The new Type 2.1 is the culmination of all these updates.” So, while Type 2.1 is something new, its not technically new to the XX1 Black group, as it appears to have already been in production on red colored XX1 groups for some time.
Thanks to our readers for being detailed in their viewing of the photos!
