I have had a Cinelli Mash Parallax (alu) and now own the steel Vigorelli, both used for track racing.
Here are some points based on my experience
- Steel Vig paint work is incredible, people ask whether its custom. It's really that great. The sparkles are all difference colours and on the black finish with the silver logos it does look like a mobile disco of radness
- Steel Vig forks are 45mm rake which means no horrendous toe overlap so better for everyday application
- Steel Vig has longer wheel base so less skipping when sprinting (in my experience)
- Get the steel one
Steel is just so much more rad in all cases. It looks the business, has better geo (in my experience), its plenty stiff enough for racing (it uses Columbus Thron which is hefty stuff). Its a bit heavier, but who cares? Its much much more rad
