Bicycle and Pedal Thread
A bicycle consists of a vast number of large and small components, many of which have threads. Often, multiple thread types are used on a single bike, and these can vary greatly by region. In Germany, in addition to the standard metric thread, the bicycle thread standardized according to DIN 79012 and abbreviated as Fg is also commonly used. It is also applied to mopeds. In bicycle manufacturing, it is especially important at the pedals. Here, both right- and left-hand threads are used to prevent the pedals from unscrewing during pedaling.
Everything you need to know about the bicycle thread (DIN 79012)
The Fg bicycle thread is originally an imperial thread, although its nominal diameter is often given in millimeters. This leads to values with up to three decimal places, which may be rounded. The pitch is specified in threads per inch. The flank angle is 60°. The thread designation consists of the abbreviation Fg and the outer diameter rounded to one decimal place, e.g., Fg 2 or Fg 2.6.
The bicycle thread is typically used at highly stressed points such as bottom brackets or axles. Pedals have a special requirement: the left pedal uses a left-hand thread to prevent unscrewing during rotation. The right pedal uses a right-hand thread. This ensures both pedals remain secure during rides.
Bicycle and pedal threads – Our range
In the BAER online shop, you'll find everything you need for mounting or repairing bicycle components. All of our threading tools are made from high-quality materials with precision manufacturing to help ensure your project is a success!
Taps
Whether for manual or machine use – BAER offers the right taps for bicycle and pedal threads. Our HSSG forming taps are an excellent choice for flexibility. They can be used by hand or in machines and cut the thread in a single operation. We offer them in all common sizes, including the classic Fg 14.3 – both as right- and left-hand thread.
If you prefer to work completely manually and independently of machines or electricity, our hand taps for bicycle threads are ideal. All sizes are available in practical two-piece sets (pre-cutter and finisher), including Fg 14.3 for left-hand threads.
For demanding applications and high volumes, our machine taps are a perfect choice. Made of robust HSSE, they fit into any stationary drill press. Fg 14.3 is also available in left-hand thread for pedals.
Dies
Whether you're repairing, rethreading, or manufacturing – BAER dies make it easy to create external bicycle threads. Our round dies can be used manually with a die holder or in a machine. We carry all common sizes of bicycle and pedal threads, including Fg 14.3 as both right- and left-hand thread.
