TA Bottom Brackets

TA Carmina cranks have ISO tapers, and so require bottom brackets with ISO tapers. TA makes the Axix bottom brackets as the perfect match for their Carmina, Carmina Compact and Vega cranksets. The Axis uses industry standard sealed cartridge bearings. The retaining cups each have an additional lip seals to keep water away from the bearing seals. Should a bearing ever need replacement, they are a simple press fit to the axle.

These precision made bottom brackets require that the frame's bottom bracket shell be properly faced with high quality tools made specifically for that purpose. In my shop I use Campagnolo, but there are others available. Any good bike shop will have suitable tools.

TA Lock Ring Spanner

All Axix bottom brackets use an aluminum lock ring to save weight. The lock rings have 6 notches for the lock ring spanner to engage. Older steel lock rings can be engaged with just one notch, so older lock ring spanners typically have one hook to engage a notch. But the aluminum lock ring must have all of the notches engaged in order to prevent damage to the aluminum, which of course is softer than steel. So you must use the TA lock ring spanner with the Axix bottom bracket.

If a ham fisted mechanic decides to use a standard spanner and damages the lock ring, don't despair, I stock spares. See below.

TAOU-BO01 TA BB Lockring Spanner $24.00
TA Spare Parts

Replacement lock rings for the right cup of the older Axix BB with both cups adjustable are no longer available. If you should damage the right side lock ring, which has a left hand thread, you'll need to replace the right cup with the newer fixed type, which is fully compatible with the axle.

TABO-00212 TA BSC left side adjustable cup (with water seal) $34.00
