The tubes are very light steel on this one-about as light as I dare go for a frame that will see full seasons of 'cross racing in Nor-Cal.
The downtube is True temper S-3. The top tube and rear stays are Columbus Life. The headtube is for a 1 1/8" steerer and the bike will have cantilevers so this one isn't as much cutting edge as it is traditional.
The Paul's dropouts will have adjuster screws and the bike will be fitted with a Ritchey carbon fork. I have a number of bikes out there with this tubeset and it gets consistently good remarks from the riders. Maybe my next road frame will have this set.
