The Syncros FL Micro-Adjust Carbon Fiber Seatpost

It did take a while, but the use of carbon fiber as a material for mountain bike parts and frames is currently almost as common now as it is in the tennis industry where they've been using carbon fiber to make rackets for more than twenty years.

In the past, most component fabricators have stuck with less exotic materials like steel and aluminum when it came to make cranks ans seat-posts and bar ends. But currently it seems like every mountain bike part manufacturer has some carbon fiber offering in their line.

Syncros, a company long renowned for its rugged light aluminum stems and posts, and, for their cranks, rims and other components. They also have several carbon fiber products.

Carbon fiber has been eschewed in the past by bike manufacturers because it has a reputation for being expensive and difficult to work with, and by consumers because early, ill-designed carbon fiber products had a tendency to break at the wrong time. And when a carbon fiber component breaks, it sheers right off, without warning. But luckily those days are gone.

The Syncros lightweight carbon composite FL Micro-Adjust Carbon seatpost is among the lightest on the market – 210 grams in a 350 mm length. The seatpost head is made from cold-forged aluminum and features a micro adjustable for precise seat angle control.

Syncros claims a strength-to-weigh ratio for the carbon fiber seatpost 5.5 times greater than for their already-strong 7075 aluminum seatpost, and a fatigue life for the carbon fiber seatpost over ten times as long as the 7075 aluminum seatpost.

The carbon fiber shaft is table rolled to ensure a consistent fiber-to-resin ratio and to deliver low loid content and more consistent wall thickness than bladder-molded products.
