I have been curious and impulse bought a Fizik Antares in Liquigas color scheme.
Tried it for two rides and came to the conclusion that I should stick with what works best for me which is a Spesh Toupe that I have been using for years.
Rails are hollow Maganese . Very good condition as I rode it on two rides . Couple of creases in the upper as seen in pic but this is normal . Made in Italy
