The clean simple lines of a single speed bike are undeniably elegant, but there are times when one gear simply isn't enough. In keeping with the simplicity single speeders strive to maintain, we developed the DOS ENO freewheel. Two gears on one freewheel. The chain is manually moved from one position to the next which allows the rider flexibility when riding in a situation that demands an easier or harder gear. We offer the DOS in sizes 16/18 (blue lock ring) and 17/19 (red lock ring). Designed for 3/32 chain size also works with 6, 7, or 8 speed chains. Freewheels have long been the Achilles' heel of the single speed industry. The problem has been twofold; 1 dirt gets inside and gums up the mechanism 2 the inexpensive freewheel unit is not precision enough and bearings are easily compromised. Both of these problems plague the consistent engagement of the typical or average inexpensive freewheel.
Sometime it may engage at 15 degrees and sometime it may engage at 9 degrees. A true precision freewheel will engage at precisely 10 degrees consistently. Consistent engagement is necessary for proper training and conditioning and is MORE IMPORTANT than having more engagement points.
I would rather have a precision freewheel with 36 engagement points than a cassette with 72 engagement points that is NOT precision quality. White Freewheels have superior seals and do not require much maintenance, HOWEVER they are completely rebuildable by the average bike enthusiast. You can feel the quality just holding one of these unit in your hands. Give it a try and if you are not satisfied when you get it you can send it back for full store credit. Just do not install it. This Freewheel is design to thread onto a standard hub 1.375 x 24 tpi. On a Flip Flop type hub this is the larger threaded side.
