The weblink is long, but I've pasted the blurb below.

--Take advantage of that bar top position! In-line brake levers allow confident braking from the bar tops on any drop bar equipped bike with brake cables under the tape. To install simply peel back the last inch of tape, cut the cable housing, run the inner wire through the in-line lever, and adjust your brakes as normal. After a few rides you will want them on all your bikes, the best 85 grams you ever added to your bars. Works with most cable operated brakes. --

Now that I think about it, you'll have to take the wire off the calipers to get it in the clamp, no? Yep. I decided to sleep on it, and that's what I've realized. I thought maybe there was some device that encased the cable without having to disconnect it anywhere, but no. You disconnect the one end from the caliper, run it through the lever, and then reconnect it to the caliper.

In your case, disconnect the cable from the caliper, unwind a bit of bar tape, remove the cable from the brake lever, and then remove the lever from the bars. Rewind the bar tape, reattach cables, adjust brakes, and you're done. The length of the cable housing might be an issue. Maybe not, since it looks like you have extra bar tape wrapped up around there. Just carry it on more toward the center and to meet the housing.

No, wait, wouldn't there be a gap in the housing then? That could be a problem.

I definitely think you can do it yourself. You could, in fact, mark the cable in some way so you know precisely where it was in the caliper before you disconnect. At least that would be a starting point for readjustment.

When/if you get done, let me know. I'll be happy to take them off your hands.
