Porsche has problems with one of its niche segments.
All 2,540 Porsche mountain bikes sold between August 1998 and July 2001 are being recalled because of a production flaw. The carbon-fiber stem, which connects the handlebars and the front fork, could break.
So Porsche will replace the part with an aluminum stem. For 500 bicycles with carbon-fiber seat posts, Porsche also will replace the parts.
Normally, it's harder to find bicycle owners than car owners. But the Porsche bikes were sold only at Porsche car dealers. So Porsche may already know the owners -- provided that they also bought sports cars.
