Standard Road Bike Fork Width

The type of road fork you choose will depend on your bike type and the type of riding you wish to do as well as on additional factors including steerer tube size.

Standard road bike fork width.

Fat bike fork with 135mm skewer typical rear hub standard and front hub spacing. Most every modern disc brake road cyclocross and gravel bike uses a 12 100 front hub standard and a 12x142mm rear hub standard. The longest the tange crmo tig unicrown fork can be found on many production road bikes made in the mid 1990 s. The big wheeled mountain bikes known as 29ers also use this size so there are off road tyres up to a whopping 75mm wide.

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. Forks have several key dimensions which include. The shortest the tange 7b crmo is brazed with a traditional semi sloping crown and represents what for many years was the standard brazed steel fork. Tyre widths available for the 700c 622mm size standard vary from 18 to 47mm with popular widths such as 23 25 and 28mm in the mix.

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. Use of a good quality and sharp hack blade is needed for a properly cut column. Older bicycles used narrower spacing but older frames can often be spread out to match more modern wheels. Most road bikes come with a 700c wheel but road bikes for much smaller riders can use a smaller size like a 26 wheel.

A bicycle frame and fork should match the wheels that are to be used in it. Offset length width steerer tube length and steerer tube diameter. Normally a 135qr hub had disc brake mount spacing that was specific to the rear brake different from the front spacing. Some bikes like trek s split pivot full suspension bikes use thru axles that are up to 50mm longer than the hub dropout width.

Bicycle forks usually have an offset or rake not to be confused with a different use of the word rake in the motorcycle world that places the fork ends forward of the steering axis this is achieved by curving the blades forward angling straight blades forward or. 6 cutting steering column threaded. This tool holds the fork square to the saw blade. 135qr was originally a rear hub standard until fat bikes came along and flipped everything upside down and sideways.

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.
