Looking for solution for using STI with a 1x
I recently rebuilt a '99 Cannondale R300 into a flat bar 1x8 - keeping the original Shimano RSX 8-speed cassette, and adding a single trigger shifter for the rear. But now I'm looking to put drop bars back on it, but leave it as a 1x8. What kind of STI solution is out there for this? Do any companies make a set of integrated levers with only rear shifting capabilities?
Thanks!

Alternately, you could use Shimano STI levers and just not use the front shifter. Or you could use plain brake levers and a separate shifter, like a bar-end shifter. Or, for a particularly avant-garde solution, you could use an 8-speed right shifter and a mismatched left lever.

All SRAM road setups are available as 1x, where the left brake lever is just a brake. Unfortunately, they started out with 10 speed, they've never built 8-speed for road bikes.
Mismatched levers has been done before back when some people (see this guy below) preferred having a downtube shifter for the FD. Alleged reasons included lighter weight and easier to trim.

The weird thing is that Shimano has kept a drop-bar brake lever in their catalog (currently the BL-R400), but the body shape and styling hasn't really changed since about 1990.

This might be a dumb question, but why not just not cable the left shifter?

If you'd consider going all the way to 11 speed, an R7000 right lever and a TRP RRL left lever in black would look quite nice.

I would sooner buy the microshift over claris and just get the 1x version which would look smoother and cleaner and from my experience shift better. But if I already had a shifter to use, I'd just use that one.

If you wanted to get fancy, you could gut the left shifter, and stop the brake lever swinging... That'd give you matching economics without redundant bits... I guess you could grind off the shift cable port too, but it probably wouldn't do a whole lot for the looks

Thanks for the suggestions. I think that Microshift set is basically what I am looking for - I just wish the cable didn't stick out the side of the lever - but that it was all internal/under the hood/bar tape (for aesthetics). Having one looped out cable is gonna look weird methinks.

I wonder what the 9s Campy cog spacing is, can't remember... I know with 8s, Shimano was 4.8mm and Campy was 5.0, same as Shimano 7s. So if it's close enough to 4.8mm, you could rock campy 9 on your Shimano 8, and the Ergos are far more amenable to being gutted of the shifter.
Or you get a Shiftmate and use 8s levers with your Shimano derailer.
