What size is the Look 496 headset. he front of the look seemed narrower than the new Felt DA’s. I see the Felt has a one inch headset so what size headset does the Look use?

Does using a 1 1/8th headset cost some of the TT/tri bikes in the Aero stakes?

The extra 1/8" easily costs you 20 minutes in an IM.

not to mention the extra weight affecting your climbing. (add on another 15 minutes or so)
