Kind of a threadjack... Hmm, I was on my morning ride today and saw two guys riding next to each other (Well, they pulled up to me at a stop sign with friendly faces; maybe it was my tri top). I thought they would go faster due to the whoosh wheels and gear they were wearing, so I let them go in front of me. They begin to ride at a 17-18mph pace, and I kind of got stuck behind them. Using BF etiquette, I hung behind their paceline about 15 feet so they didn't confuse me with being a leech. At the next stop light, they take up the entire front of the bike lane so... Hmmm... In the next 1/2 mile or so, I get a little anxious and pass them at 19-21mph and don't say anything while passing. If you guys were the two pair paceline, would this have been ok?
