PF30 SRAM GXP
PF30 road bottom bracket shells are 68mm wide like BB30, but have a greater diameter, 46mm, so that bearings in cups can fit inside the shell. This kit contains all the parts you need to install a Quarq or SRAM 24/22mm spindle crank in a PF30 road or cyclocross bike.
The bundle comes with two cups and CeramicSpeed bearings installed. There are two choices. Standard and Coated. The both possess super smooth CeramicSpeed balls fitted in hardened-steel races. The Coated have an additional feature: a 3-micron thick metallic layer over the races. This addition makes the races smoother and harder, lowering drag and increasing life.
In The Box
- 2 cups with bearings installed
- 2 dust covers
- GXP wave washer
- Spacer tube
- 10ml syringe of CeramicSpeed All Round Grease
- Sticker sheet
- Frame: PF30
- Opening diameter: 46mm
- Shell width: 68mm
The cups have extended sleeves, are joined via a spacer tube, reducing the likelihood of creaking and increasing the reliability, as well as protecting internal cabling from the 24/22mm crank spindle on SRAM and Quarq cranks.
The Standard Bearings have a friction cost 0.3-.04 watts per set, an average drag reduction of 75% compared to stock bb’s. The result of smart design: hardened-steel races, and ceramic balls that are 100% smoother and 15% harder than even the competition from fellow ceramic bearings. They also last longer.
Coated Bearings feature an even longer service life and feature even lower drag. Life increases by 60% and drag drops by 50% compared to our Standard.
All Round Grease is installed in the bearings. It can be replaced for lower drag TT and Track Grease, or higher durability LongLife Grease, which adds a bit of drag but stays in when riding through messy conditions.
The Coated Advantage
6-Year Warranty Program
CeramicSpeed’s coated products offer the ultimate gains in performance and longevity. Our proprietary coating features several attributes that improve the longevity of CeramicSpeed Bearings. The increased hardness of the races, combined with the smoothness of theCeramicSpeed Balls results in virtually no wear on the bearing.
Within our comprehensive R&D program, the special coating has been developed in cooperation with a European coating specialist. Applied to the bearing’s steel races, through an advanced process that ensures an even, smooth and homogeneous surface, the coating formula improves even further the high quality of CeramicSpeed Bearings.
Thanks to the coating’s high resistance to corrosion – even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible. We recommend choosing CeramicSpeed Coated Bearings for unmatched longevity and incredibly low friction.
Like all CeramicSpeed Bearings, our coated products are handbuilt in Denmark. Building a coated bearing adds a number of extra steps to the process. The CeramicSpeed balls and steel races are matched to the micron after which, each set of races is coated. The races are kept together in pairs through the entire process and after coating, each set needs to pass the quality control before they go into production.
