Ordering cassette advice

I need to order a new cassette. I have a 9 speed Ultegra componets. I checked the existing cassette it is a 12 - 25 cs hg50. When I have checked I have found this cassette along with a Ultegra cassette. Wha is the difference between the two cassetts. Are there any cassettes that won't work with my existing setup?

I have always been able to use either Shimano or SRAM 9 speed cassettes interchangeably with my Shimano drivetrain without incident. Shop for the ratio you like and purchase :-)

mind that some of the cheaper sram cassettes are pretty shotty, cheap materials, and can be noisy and have a way shorter life than the nicer Shimano ultegra, dura ace stuff

I have easily ridden 2,000 miles with the bottom of the line SRAM and Shimano cassettes - I have to disagree with the above. Unless you are doing some specialized riding that requires exceptional performance, it is my opinion that paying more for Ultegra/Dura Ace is a waste of money. Just be sure to maintain your drivetrain (applies to any level of component).

That being said, I have been told by the wrenches at Performance that their own brand (Nashbar included) fall into the category described by MadBuddha.

+1 I have had good service with lower level Sram and Shimano gear. The more expensive stuff buys you lighter weight (marginally), and better finishes--not necessarily longer lifespan.

One cassette to avoid is Campagnolo, the internal spacing is not compatible with Shimano.
Dura Ace and high end SRAM have titanium components that were out 'rapidly' compared
with standard steel and have unbelievable prices. Some cassettles have shiny plating,
that quickly disappears under grease and dirt. Suntour and other inexpensive cassettes
work fine but are 25% or so heavier because of the construction method. 105, Tiagra,
Ultegra and the lower end SRAM are all good choices in 9spd.

Bikes: '''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!

They also won't fit on any Shimano/SRAM compatible freehub as their spline pattern is different so installing one isn't even possible.

Sun Tour cassettes are not compatible with Shimano indexing since their spacing is also different. Correct that all of the lower line Shimano and SRAM cassettes are compatible for a given number of "speeds".

You can use any Shimano compatible 9-speed road cassette. A Shimano 9-speed mountain cassette (32 or 34 large cog) could be used if the rear dérailleur is replaced with a mountain type RD. A new proper length 9-speed chain may be needed.
