The NEW Wilier Filante SLR iD2, finally out on the road for a proper test. I headed out to Andalucia in Spain for a quick 300km blast in the mountains. What I found was a very versatile aero bike that felt very stable in turbulent winds. The windtunnel might not mark it as the fastest, but it is a very rideable, fun and fast bike. It descends well, with a little too much bias on the front wheel. It climbs great. A really nice out of saddle character.
