For those of you who are not aware IRIS Bicycles, founded by Ben Pym and sisters Sarah and Anna Hickman, are a local outfit based in Southampton who have launched a titanium road bike called the IRIS Zero that’s aimed at racers and other performance-focused riders.
I have had the pleasure of working with a couple of IRIS bikes in the past and have always admired them, this time however, I got to take one home with me.
I have been looking at buying a titanium frame for a while now but I chose IRIS over other brands not because of price, but becuase of their passion for the product and what they do. Talking to Ben about the material used and construction of the frames fills you with confidence, and its customer service and attention to detail like this that you just wouldn't get from other suppliers.
The frames tubes are double butted 3AL-2.5V titanium and the machined parts – the bottom bracket, head tube and dropouts – are 6AL-4V titanium.
I mostly went for Dura Ace 9070 Di2 groupset on the build with a few neat additions including the new BT-DN110 battery to enable syncro shifting and wireless diagnostics, the bluetooth inline wireless sender unit and the new bar end junction box to neaten things up front. All of this paired with the Miche SWR 38mm wheels weighs in at 7.7kgs which I think is pretty impressive for a metal bike!
