How do I wire these up? Do I need to remove all these bottom screws in the third pic? I also see what looks like a small access hole in last photo. The front shifter has a rubber plug for this hole. Is that cable routing access?

I haven’t found instructions online. Not sure what to even call these. Whenever I google l get different models. I bought them on eBay and the plan is to do an upright conversion on a road bike equipped with a standard Shimano 10-speed cassette and 10-speed Ultegra RD. In the front is a FSA compact crank and I assume an Ultegra FD.

use the top foot to release both shifters. and opens in the hole for inserting the cable. sorry for my english

I cannot tell which shifter model you have but one of these instructions should get you close:

Basically, you want the shifter to be in its mostly paid-out cable position to be able to install/remove the cable head from its cavity.

Yes -- put the shifter into its most "relaxed" position (Low for the left shifter and 10 for the right shifter) and pass the cable through that small hole. It should pass straight through the shifter mechanism and out through the barrel adjuster. You may have to play with it some to get it through, but that's the intent.

Were they sold as road shifters or mountain shifters? It's hard to tell from Microshift's website what they may be. They don't look like Centos or R10, but they may be from an older 10-speed road group. I think you'll need road shifters, as 10-speed road and 10-speed mountain use different actuation ratios.

Thanks for all the tips guys. Easy. In fact, the entire conversion went smooth except for dialing in the indexing, but I've got it 90-95% there.

It makes for a fast runabout, and beats all my vintage machines in terms of feel and responsiveness. The frame is more compact than I'm used to but I'm sure that (plus the tires and the weight) contributes to the zippiness it has.
