Ultegra or 7800.
Are you saying that 6600/7800 cassette are heavier than 105 cassette????cxwrench said:as he was saying 'upgrade' i'm wondering about this...
6600 is heavier, but will wear well. 7800 is also heavier, and has some ti cogs which will wear faster. not really an 'upgrade' in my book.
Yes, the 6600 is heavier than the 105, but not by much. It's about durability here. The 7800 is essentially the same, but with the last 2 (I think?) cogs being titanium for weight savings. If you don't use those cogs, then the DA cassette will last a long time too.cpark said:Are you saying that 6600/7800 cassette are heavier than 105 cassette????
I'm generalizing "upgrade" as moving up on the componentry hierarchy, not base on wear.
Yes. Ask the guy whose Red cassette doesn't work.petehm said:Let me rephrase the question. Is there any noticable difference in shifting performance between Sram Red and Dura Ace 7900 cassette when using a Shimano chain?
the guy with the red cassette complaints has got some other issue, otherwise you'd be hearing about it from a lot of others.CleavesF said:Yes. Ask the guy whose Red cassette doesn't work.
Shimano works best with Shimano, SRAM with SRAM. I dont' understand this "interbrand" stuff. You guys know what I mean.
