Good or bad is
a matter of opinion and it's a bit of a sensitive matter apparently. Give some of those threads a read for a comprehensive collective opinion.
Edit: All better, thanks never.
Don't forget the brakes. One thing SRAM has not done is labeled things consistently across their acquisitions. They really need to correct this in the future by putting EVERYTHING in the X numbering series.
X.0 - Juicy Carbon - SD Ultimate - Stylo Carbon/Holzfeller
X.9 - Juicy 7, BB7 - SD 7 - Stylo/Husselfelt
X.7 - Juicy 5 - SD 5 - Ruktion/Firex
SX5 - BB5 - Blaze
SX4 -
That's the best I can make out. I think that Truvativ and Avid have lower end products that aren't on the website that would be speced out to OEMs (along with SX5 and SX4).
BTW whoever thought of the SX moniker for SRAMs new low level OEM stuff wasn't thinking. I see that and think, SuX4, SuX5.
Hopefully in the future SRAM will enforce a common group naming across it's divisions. They also need a pedal aqcuisition (Crank Brothers or Time) and hub acquisition (Hugi or Swiss) to compete head on with Shimano in EVER category.
