I had a 54 x 40, but downhill I was looking for something bigger. Rotor is stiff, reliable, and light. Perfect for the time trial bike (Translated review)

Good product, gears shift well, be careful you will need an adapter to raise the derailleur in Ultegra, maybe not in Dura-Ace...? (Translated review)
