The photos, up close















A single piece
T1000
Toray T1000 carbon fibre, the high grade in the range. Bar and stem come out of the same piece, so there are no bolts in between and no play appearing after a thousand kilometres.
The profile is worked out to take the twist of a sprint and hard braking, while leaving some flex where rough surfaces punish your hands.

Before you order it
Two numbers: bar width and stem length. If you already ride comfortably, copy the ones from your current bike and don't overthink it.
