Sun Ringle has released a hot new product for 2011, the Dirty Flea Single Speed cassette hub. Just like a lot of Sun Ringle hubs, the 2011 Sun Ringle Dirty Flea Single speed hub features outstanding durability and smoothness.
Comparing to the traditional freewheel single speed hub, the hub is a unique item. The smaller cassette body of cassette single speed hubs do not force the rider into one static position for the rear cog.
Fine-tuning the position of the cog is easy with the single speed hubby Sun Ringle because it is equipped with only a few spacers. Through this, the impeccable chainline with almost any crank set up is guaranteed. Multiple single speed gears or a mini geared set up is allowed as well.
