What Jeff said. Longer answer: That gearing goes beyond the capacity of your rear derailleur, so you can expect that if you have sufficient chain to wrap around a 52/34, then if you ever use about your 24/15 (or smaller in back) you're going to have slack chain. That's why the older EasyRacers had a pair of jockey pulleys where your return idler is -- to take up more slack. Just don't use your small ring with any more than the largest 3 or maybe 4 gears in back. If you do, you're probably still OK even though it might look bad. Certainly better than not having enough chain for your 52/34 and accidentally ripping the derailleur off the frame, destroying your rear wheel in the process!
