Vredestein have just changed to stripes for most of their tyres for their 2006 range, but there are still heaps of all-red (a light red), 2004/2005 TriComps out there. They're not 100% red; they have a very low, tanned side-wall. They look like this, but in red, obviously
Veloflex Pave may come in a ALL red tire.. not sure though. Vittoria may also have one. I've seen red tread... but its tough to also get red side-walls
