I do not care about originality as it is not a rare bike. I just want to make it a nice rider. I though about adding a threadless adapter, but it does add a layer of complexity to the bike. It really comes down to the bars I decide on. My current stem is 25.4 so the Soma Brevet Ergo bars would work, just not sure these are the right bars for the bike.

I thought I was set on bar end shifters, but I am thinking the Microshift STI shifters again since there are a lot of hills where I am.

How do you like those SCR-5 levers? I was looking at a pair on eBay earlier today.
