Crafted in a skin fit and offering medium-impact support, the Ronhill Women's Seamless Sports Bra is built for multi-activity use. Featuring high stretch fabric with a seamless knit construction to keep you free from chafing and removable pads enhance the fit. The soft fabric construction is breathable and fast-wicking so you remain dry, comfortable and distraction-free.
The Press Fit 4630 will easily accommodate your handpicked rig with its press fit, 46mm 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.
FOR BBRIGHT SPECIFIC FRAMES. CONVERT TO 24MM AXLE Rotor Pressfit30 PF30 4630 Ceramic Bottom bracket available from Velotech Services For use with BBRight 46mm systems to convert down to 24mm axle systems. This can be used with cervelo BBRight frames for Rotor 3D & Agilis cranks.
Ceramic Bottom Bracket cups.
The new, advanced non-contact Labyrinth seals yield a buttery-smooth spin with unparalleled protection against dust, water and mud. Ultra rigid plastic caps give high compression and deformation resistance, facilitating crisp shifting. Constructed of CNC machined 7075 aluminium. Adaptor cups and bearings for the installation of 24mm cranks in BB30 PF frames.

Ceramic bearings for improved performance and longevity.
Rather than relying on the pressfit shell for alignment, the UBB4630's threaded sleeve locks both cups in place, increasing BB shell stiffness. This also ensures a smooth, uniform spin free from creaks that often plague pressfit while preventing bearing overload. The perfect alignment also means longer bearing life while the sleeve also prevents cable guides rubbing against rotating parts. "The motive for the UBB4630 was to address challenges related to bottom bracket installation and durability with specific frames," said David Martinez, head of engineering at Rotor.
