Velo-Perso.com’s Review
"The T47 is a modern standard found on a growing number of prestigious frames combining stiffness and aerodynamics, like Trek. This ceramic version is the ultimate solution for a T47 internal setup with a frame width of 85.5 to 86.5mm and a Rotor 30mm crankset (Aldhu, Vegast, Aldhu Carbon, Inpower, 2Inpower). If your budget allows, this is the optimal choice. Its excellent sealing prevents contamination of the bearings by sand or other impurities."
