You had your choice of any bike in the shop but you made your selection based on potential upgrade options. The Press Fit 4130 will easily accommodate your handpicked rig with its press fit, 41mm diameter with 30mm axle BB shell. ROTOR conceived its Universal Bottom Bracket (UBB) concept to eliminate the complicated bottom bracket/crank compatibility challenge that has increasingly frustrated the mechanics at your LBS. The Press Fit 4130 is the "yes" component to "Is this compatible with my press fit 41mm diameter BB shell for a 30mm axle?"
Are you single yet? We wanted you to be able to experience all the benefits of QX1 chainrings for your Cannondale, SRAM, or Specialized cranks so we designed a range of QX1 spiders to pair with your 1x cranks. So don't worry if you have a Cannondale F-Si Ai, SRAM GXP® or BB30, or Specialized cranks for a single Q rings, we've got a spider that's compatible with your cranks.
SHORT DESCRIPTION
Our VEGAST® and ALDHU® spider features a cleverly designed spline interface when mounted to the axle that delivers a robust yet smooth engagement allowing you to maximise the efficiency in transmission of power in your pedal rotation. Combined with our new VEGAST® / ALDHU® cranks and Q RINGS oval chainrings or Round chainrings, the innovative spider includes refined OCP Mount technology so you can now adjust your optimal chainring position by precise one degree increments.
SHORT DESCRIPTION
Two spacer sets to fit all standard BB shells.
The ROTOR spacers are manufactured in Aluminum 7075 and allow the cranks o be centered and adjusted, thus eliminating the possibility of gaps and misalignments.
