Downtube to STI conversion Questions. Cable stops + STI compatibility

I was planning on converting my Cannondale SR500 to STI shifters and was looking for cable stops as a result. I noticed there to be two different kinds.

Amazon.com : Shimano Housing Stop for 1-1/8" Down Tube : Bike Shift Cables And Housing : Sports & Outdoors

https://www.amazon.com/Shimano-Down-T.../dp/B001JH82Q2

Is there any difference? Does the one with the winged lever justify the added price? And I'm assuming any shimano shifting cable will be fine for the conversion?

Also, I was wondering if the STI shifters I have is compatible with the rear derailleur. I have the shimano RSX 7 speed shifters and the rear derailleur is shimano RD-1050. It's currently running friction shifting with 7 cogs in the back no problem.

The winged lever ones may be from the Dura Ace parts list. cross reference the parts numbers on the Shimano website.

compatibility is a really FAQ.. maybe an 8 speed brifter will work , I havent tried , myself. good luck :|

I stick with friction shifting and bar end shifters ..

Functionally, no. Those downtube cable stops double as barrel adjusters. The winged ones just make on-the-bike adjustments easier than the other one.

Also, I was wondering if the STI shifters I have is compatible with the rear derailleur. I have the shimano RSX 7 speed shifters and the rear derailleur is shimano RD-1050. It's currently running friction shifting with 7 cogs in the back no problem.
Yes, they are compatible. Shimano road components are pretty interchangeable, except for a certain Dura-Ace series. I've had a similar setup (although reverse) using a RX100 RD and modern 2300 STI shifters.

Also note their are 2 types of these Flat and Curved, I did this conversion to my old Cannondale SR500 I used the curved one's on mine so it fitted the down tube contour.
If you have questions you can PM me if you like as I have done this same bike.
Regarding your STI levers yes they are.
