This is wrong. The racer set dislikes the triples because gearing that low is absolutely useless for racing. If you are going so slow that you need something like a 30x25 then you are getting dropped anyway. For example, a race I'm doing this weekend has an 8% climb, last year I "spun" up it at 90rpm. I don't recall what gear I was in but I had a 53/39 with an 11-23 cassette so it couldn't have been any lower than a 39x23. According to the gearing calculator it was probably 39x21. If you needed a triple to get up that, you wouldn't be percieved as week, you would be week. For steeper or longer climbs I may use a wider cassette, and plenty of [strong] racers use compacts as well. But there is just no use for a triple in racing (with the exception of maybe some of the mega-steep pure hillclimbs).
