Frame Prep
Frame Prep is one of our services that make our tailor bike building service stand out from others. It is one of the most important jobs in bicycle service lists, often the most neglected job by many people. Frame prep also creates a solid foundation for performance and longevity, while skipping it usually shows up later as noise and premature failure.
Frame prep involves thoroughly inspecting and measuring the bicycle frame to identify any corrective work needed to boost performance and extend component life. The heart of doing this job well comes down to one word – precision. It requires significant skill and experience because it’s far more than simply applying tools. This demands careful evaluation of tolerances, alignment, and specifications before any work begins.
The goal of frame prep is to ensure that, before the bike is built, all mounting surfaces and component interfaces meet the required tolerances so everything fits and functions flawlessly. There are three different frame prep services and they are: facing, chasing, and reaming.
Facing
Facing – This is to create a perfectly flat surface by removing excess material such as paint, metal and carbon from uneven surfaces.
Applicable for bottom bracket, head tube and brake mount.
Chasing
Chasing – For threaded bottom bracket and thru axle drop out. This task is to ensure the threads on the frame are completely clean, smooth and free from debris.
Applicable for bottom bracket, brake mount, other female threaded interface such as thru axle thread and rear derailleur hanger.
Reaming
Reaming – For press fit bottom bracket shell and headtube. This is to remove excess or uneven material such as carbon or resin which to achieve the desired tolerances (roundness).
Applicable for press fit bottom bracket shell and headtube.
