Repost from Commuting Forum:
I test drove a Raleigh Sojourn touring bike at my LBS a few days ago. Nice bike, but not nice enough to make me buy it. However, it was the first time I've ridden a bike with bar end shifters, and I really liked them. Mostly because I could shift all the way across the cluster in one motion, but also because I could tweak the position of the front derailer in order to center it on the chain.
I'm running steel North Road bars (Wald 8095) on my bike, which will accommodate bar ends as best I can tell, so I've ordered a set. I've got Ergon grips, and I'm thinking I'll just run the shifter cable along the underside of the grips and across the brake clamp, and then zip tie the cable to the bars from that point on. But I'd be interested if anyone else has suggestions. For example, is there a way to route the cable inside the bars, drilling an exit hole somewhere near the sweep?
