My understanding is that Columbus no longer sells their XLR8R tubeset. In fact, it came and went fairly quickly. If this is correct, does anyone know why? Has anyone had a shimmy problem with these tubes? I need to replace a 2003 Orbea XLR8R frameset which no longer appears in the 2004 line-up--hopefully with a model of equivalent value. Seems as if their Lobular alum/carbon frame, previously #3 in the product lineup after XLR8R may be the substitute, albeit at a very slightly heavier weight. At 165 lbs., I don't need a heavy-duty frame, but going the other way toward a Starship seems like it might be just a little too light. Thanks.
