Designed
so that the bearings rest on the axle of the crank, these BBs provide a
straight load to the bearings, which means your BB will last longer.
This also allows us to make the Prime Threaded BB with tighter
tolerances, so it runs smoother with less friction. This means you’ll
require less effort to make it up that hill or sprint for the line.
To keep our Threaded BB running smoother for longer, we use special
seals that keep water out of the bearings. We use multiple smaller
seals, which reduces friction and provides a better barrier against
moisture and dirt. Our bearings themselves are manufactured to precision
and packed with slick, waterproof grease.
With our ceramic bearing option, friction is reduced meaning less
energy is required to turn the cranks, they’re also more durable, and
don’t rust so they’ll require less maintenance. If you’re a rider
seeking out every possible advantage over the competition, the ceramic
option can help take your performance to the next level.
