Some irritating person stole my beater a few days back. I got another old road bike in poor shape and fixed her up with a nice flat bar. She has stem mounted friction shifters. At first I considered changing them, but after a few rides I think they are perfect for a flat bar. Easy to get to, easy to setup and they shift smoothly. Yay for old tech. Setting up my 27 speed deore shifters on my mtb was so much more irritating.
Lets hope this one is plain enough that it won't get stolen.
