Product Details

<div class="product-intro">
<p>
A bottom bracket built to outlast your frame. The CeramicSpeed BB ALPHA adapts a
24 mm Shimano road crank into Cervélo's BBright press-fit shell, delivering the
lowest-friction, longest-lasting bottom bracket CeramicSpeed has ever made —
so you can keep your Shimano crankset on a wider asymmetric BB.

<h2>Why riders choose BB ALPHA</h2>
<div class="product-feature">
<h3>Grade-3 Silicon Nitride ceramic balls in hardened stainless-steel races</h3>
<p>
Standard BBright adapters develop drag and creak after a single wet season,
so you end up replacing them every year and losing watts in between.
</p>
<p>
The hand-built ceramic bearing system runs ultra-smooth from day one and
stays smooth for the life of the frame — you feel less resistance on every
pedal stroke and stop budgeting for a yearly bottom bracket swap.
</p>
</div>
<div class="product-feature">
<h3>Custom seals with 500% better moisture protection</h3>
<p>
The wider BBright shell traps moisture more than narrow standards — water
gets past the seal and the bearing rusts from the inside.
</p>
<p>
The redesigned BB ALPHA seal blocks moisture and contamination dramatically
better than previous generations, so the bearing keeps spinning quiet and
free through winter training, gravel detours, and every post-ride hose-down.
</p>

<div class="product-feature">
<h3>Simplified spacer tube + lighter cups, 10% lighter overall</h3>
<p>
Old-style adapters needed a bag of spacers and a service manual to install
correctly into BBright's 79 mm shell, and the cups added grams in the worst
place on the bike.
</p>
<p>
The new design installs in minutes with fewer parts to lose, and you save
weight right at the bottom of the drivetrain where it matters for
acceleration and climbing response.
</p>

<div class="product-feature">
<h3>Custom dust covers refined through 28 design iterations</h3>
<p>
Cheap dust covers pop loose, rattle, or let dirt in — and BBright shells are
notorious for creaking when not perfectly fitted.
</p>
<p>
The fitment-optimized covers stay seated and sealed under real road and race
use, so the bearing stays clean and you don't hear any creaks or ticks coming
from the BB shell.
</p>
</div>
<div class="product-feature">
<h3>Lifetime warranty</h3>
<p>
CeramicSpeed backs every BB ALPHA for life. You install it once and you're
done.

<h2>Is BBright right for your frame?</h2>
<p>
BBright is Cervélo's wider asymmetric press-fit standard, found on most modern
Cervélo road and tri frames including the S5, R5, P5, Caledonia, and Áspero.
</p>
<p>
If your frame is a Cervélo from the last decade, BBright is almost certainly
your shell.
