The Tufo Diamond D-28 has the same diamond tread pattern, but comes in black
tread with red sidewalls. That's what I have on the blue Legnano (see
Dale's report from CduC 2001 for pics):
They feel a little bit heavy and draggy on the road, but they are very
round, no bumps at all. I think they'll handle better once the tread has
worn down a bit.
