What is fork rake on a bicycle

I doubt many folks realize all the geometry that goes into bicycle and motorcycle forks or how the rake, caster and trail effects handling. In my reckless youth, I had a shop that straightened motorcycle frames and forks after light collisions. We charged quite a lot because of the difficulty in checking accuracy of the alignment, not necessarily the work of pushing metal around with.

What is fork rake on a bicycle

A bicycle fork is not designed to withstand an impact from the front. A relatively light impact head-on into an obstacle -- a car, a fence -- which pushes against the front of the tire can bend a steel fork backward. The wheel takes the impact the same as the normal weight load, and often will be completely undamaged. The fork blades will usually bend back below the fork crown, and the steerer.

The above diagram demonstrates a possible approach to measuring fork offset or rake. Rest the steerer tube of the fork on a V-block on a perfectly flat surface. Measure the height of the fork dropout off the top of the flat surface (Dim A). Measure the height of the center of the steerer tube off the top of the flat surface (Dim B). Subtracting Dim B from Dim A will result in.

Fork offset or rake is the dimension shown. Imagine a line passing through the steerer tube of the fork. Measure from there to the center of the front hub, and you've got the fork offset.

A garage full of bikes is pretty cool. A garage with just a Thunderhawk is even cooler. The titanium gravel bike that revolutionized BBCo, Thunderhawk lends itself as a performance-minded 650b road plus bike that’s equipped to handle all road adventure rides, mixed-terrain endurance races, gravel grinders, and long bikepacking trips. Change.

The trail of a bicycle makes it easier to ride because it links the lean angle of the frame with the turning angle of the fork. Leaning the bike causes the fork to turn in that direction, because the frame is lower after the fork has turned. For each lean angle, there is a corresponding steering angle where the frame is lowest, and the fork will want to turn towards that angle while that lean.

FORK RAKE. The length between the center of the wheel and the steering axis (or the imaginary line of the head tube angle) is the fork rake (also know as the fork offset). Don’t confuse the curvature of the fork as the rake. While there is a noticeable curve to the Wolverine fork and it has a fair amount of rake, many straight-bladed forks have plenty of rake. Like head tube angle, it’s.

The issue of fork symmetry is not yet fully appreciated by the fork producers. At this time Calfee is the only company requiring a tolerance on fork symmetry. It takes a little longer to make a carbon fork that is within tolerance. The fork must remain in the mold during the cool down phase of molding the fork. If the fork has a slight asymmetry after being released from the mold, it can be.

What is fork rake on a bicycle

Forks, trail and rake are hot topics in the world of cycle construction. Each parameter is affected by the other, and by mixing them up you can produce either a fine handling machine or something with a mind of its own. As far as road and touring bikes are concerned all of this 'art' is well define.

What is fork rake on a bicycle

Trail, fork rake, and a little bit of history If you draw an imaginary line through the center of your bicycle’s steering tube (Steering Axis.) it will reach the ground at a point in front of where the wheel actually contacts the ground. The difference between these two points is known as the trail. Trail assists steering; as you lean the bike to the left or right, the steering axis moves in.

While there's a relationship between a bike's rake and its trail, it's not always obvious. In most cases, increasing the rake of a bike's frame will increase positive trail, though this depends on what kind of fork assembly you use. In order to increase the rake of a bike without making the trail too large, some bikers use raked trees. Trees.
