Shimano Dura-Ace Titanium Pedal Axle Upgrade | PD-R9100 SPD-SL

~184g after upgrade, down from 235g | TC11 titanium main shaft | Full-ceramic ball bearings | Pre-installed, drop-in design | For Dura-Ace R9100 Fully CNC machined and built around an ultra-high-strength TC11 titanium main shaft rated to withstand 1100 MPa. The housing is 7075-T6 aviation aluminium, and the contact end that meets the original bearing uses heat-treated bearing steel, balancing weight savings with durability. The original bearing design has been reworked, keeping part of the stock angular contact structure but pairing it with customized full-ceramic ball bearings. The bearings themselves are imported Japanese Kif bearings packed with imported German Klüber grease. It's a pre-installed, drop-in design, so the swap is a simple 3-step process.
