Shifters compatablility

Okay, hopefully I wont get bashed for my ignorance, but since I am biulding up a road bike and am running low on cash, I have a question that could save me alot of money. If I have a triple chaniring, and 9 speeds, can I just buy a cheaper 8 speed triple shifters for now and it work properly? I have always wondered if my setup could accept different kinds of shifters. Thanks.

No, not unless you also use a 8 speed casette, which is possible if you have a shimano hub. The reason is the difference in cog spacing between 7,8,9, and 10 speeds.

I just went through the same thing. Go ahead and save up for the 9's. The 8's are heavy and you will outgrow them quickly and end up buying the 9's anyway. I assume we're talking the Tiagra/105 comparison?

If the shifters are really cheap, you could use 8-speed bar-end shifters or downtube shifters in friction mode.
But with integrated shifters or with any other shifters in indexed mode (i.e. click click), you need 9-speed shifters with a 9-speed cassette.

If you bought Dura-ace 8-speed shifters (downtube, bar-end, or STI), they would shift correctly on a 9-speed cassette as long as your rear derailer is Shimano, but not the old Dura-ace. You may not be able to get all 9 cogs, though (especially with STI).

I run Dura-ace 8-speed bar-ends with the new Dura-ace (7700) rear derailer to get 9-speed.
