Will Shimano shifters work with SRAM cassette?

Title says it all. I bought a beat up Diamonback mountain bike off CraigsList and am fixing it up. The SRAM shifters are stiff and won't hit the detents properly. I have found Shimano trigger shifters on eBay. Will these Shimano shifters work with the rear deraileur and gear set from the original shifters?

Shimano shifters and Sram derailleur won't work together.

The cassette will work but the derailleur will not... The shifter and derailleur need to have a matching rate of cable pull to properly index with the cassette spacing. Shimano and SRAM use different pull ratios to achieve the same indexing.

Probably sounds confusing but trust us...that's the way it is.

As Moose said, shifters and derailleur must be compatible. Your SRAM derailleur is not compatible with any Shimano shifters.

1) Verify what brand rear derailleur you have.
2) If memory serves, SRAM did/does make one Shimano compatible trigger shifter, but I do not remember which model it was/is.
3) Lube the cables, and make sure they are properly routed and djusted. The "stiffness" could be caused by dry or damaged or misrouted cables.
4) If you are upgrading from 5 or 6 speed in the rear to a 7 speed, you will probably be able to adjust the rear derailleur to work for a 6 to 7 speed conversion. (A 7 speed freewheel will screw right on)
You will, of course have to change shifters. A 5 to 7 speed upgrade will need both a derailleur and shifters.
I upgraded MY 1989 KHS from 6 to 7 speed in the back. As I do not like Shimano, I replaced the rear derailleur with a used SRAM X9, and the shifters with SRAM X3 Trigger shifters, which are 3 x 7 speed shifters. No problems after several thousand miles.

SRAM shifters with names, such as "Attack", are Shimano-compatible; ones with numbers, like "X.9", are not

Try flushing the existing shifters with WD-40. Could just be a hardened grease issue.

BITD (early 80's) Sram made Just gripshifters, then they had to be compatible with the market dominant Shimano derailleurs.
