BSA for SRAM GXP Road
The BSA, or English
threaded, bottom bracket is a traditional shell size. It has an inner
diameter of 34mm and is 68mm wide. These cups thread into the BSA shell
making it possible to install SRAM and Quarq 24/22mm spindle cranks.
The CeramicSpeed kit comes
with bearings pressed into threaded cups, which are then threaded into the
frame. Those bearings consist of either CeramicSpeed Standard or Coated
Bearings. Super smooth, super round CeramicSpeed balls are rotating in
hardened-steel races in both. The Coated version has a metallic coating
laid onto the races, making it even smoother and harder, resulting in
longer life and lower drag.
Tech Data:
The cups come with bearings
installed and a sleeve is included to further seal the system from the
elements and from rubbing on internal cables.
The Standard Bearings have
only 0.3-.04 watts of frictional drag per set, an average drag reduction of
75% compared to stock bottom brackets. This is the result of superior
design including hardened-steel races, and ceramic balls that are 100%
smoother and 15% harder than the ceramic competition. They also last 3x
longer.
Coated Bearings last even
longer and feature even lower drag. Life is boosted by 60% and drag
plummets by 50% compared to our Standard.
All Round Grease is used 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.
Installation of BSA for
SRAM GXP Road
If you don't have any
experience installing bottom brackets and bearings, we recommend that you
have your local bike shop fit your new bearings. Find your nearest
retailer.
