The triple Tiagra front derailleur (maybe 4403?) went out of adjustment on my '06 LeMond. Was trying to keep the bike with same components that it came with, but I've already replaced 2 (one on wife's bike and one on mine previously. Seems they have a "nub" that the spring rests on and the nub broke on the previous 2. Replaced the one on my wife's bike a while ago with a Microshift R-539. Seems well made, works perfectly, stays in adjustment. Waiting for a Microshift now for my bike. Wasn't easy to find someone with one in stock. They don't show it on the Microshift site, but I contacted them and they said it is still made. Another Microshift triple fd is back ordered on many vendors sites. Just glad if found the one I wanted (the vendor only had 2-now 1).
