Remedial work needed to fix potentital fork steerer failure

Isaac have issued a voluntary recall on all complete bikes and framesets made since 2004 after discovering that certain stem and spacer combinations can cause the fork steerer to fail.

If you've got a post-2003 Isaac, you need to take it to your dealer who'll be able to check for signs of damage and also fit a new expander to the steerer.

Other recommendations include:

  • Profile Lava 3D stems to be replaced by a compatible stem
  • FSA OS99 stems with an inner collar (where the clamp meets the main stem tube) measuring less than 5mm need to be replaced
  • Max 30mm of spacers beneath the stem, and a max stem clamp height of 45mm.
  • assembly instructions from the manuals at http://www.isaac-carbon.info/17.0.html?&L=1 must be adhered to when rebuilding the bike
