A bicycle frame and fork should match the wheels that are to be used in it.

Depending on the kind of bike you ride or want to ride will determine your size along with your riding style.
A 1996 survey of 13 700c road forks found a maximum length of 374 7 mm and a minimum of 363 5 mm.
The head tube of a bicycle is sometimes designated by the fork steerer column it accepts.
Older bicycles used narrower spacing but older frames can often be spread out to match more modern wheels.
6 cutting steering column threaded.
For example frames that take one inch 25 4 mm steerer columns can have three different inside diameters for threaded and threadless headsets not.
Some wheels and forks have swappable end caps or dropout inserts allowing for the use of either 12 or 15mm front thru axles.
Touring bikes have a long wheelbase due to a combination of a slack head angle long fork rake and long chainstay length.

It is recommend to use saw guide sg 1 1 column sg 2 1 1 8 column or sg 3 1 1 4 column to cut threaded steering columns.
Most cyclocross forks will be designed for wheels with a diameter of 700c and typically have greater clearance than standard road forks to allow mud caked tyres spin freely or to enable the use of wider touring tyres 28mm and up.
For example mountain biking is a lot more aggressive than road biking and may require a smaller sized bike to make it more maneuverable through different terrains and obstacles whereas a cross country racing bike may be sized slightly larger to allow more speed to be generated.
The length of the fork is usually measured parallel to the steerer tube from the bottom of the lower bearing race to the center of the front wheel axle.
Touring bike 445 470mm road bikes 405 415mm cx 420 435mm.
This can lead to confusion since head tube inside diameters are dependent on the headset standard.
Mountain bikes mostly use a 15x100mm front thru axle and you might still find a few road bikes that adopted that standard early on but 12 100 is more future proof for road.
The longest the tange crmo tig unicrown fork can be found on many production road bikes made in the mid 1990 s.
Most road bikes come with a 700c wheel but road bikes for much smaller riders can use a smaller size like a 26 wheel.
The spacing of a frame fork is measured from the inside surfaces of the forkends dropouts where they come into contact with the locknuts of the wheel s axle.
This critical characteristic of fork length needs to be accounted for since a fork that is too large for your bike s wheel size will negatively impact the handling of the bike.
A longer wheelbase provides a more stable and comfortable ride.
