The cup has a square face to reference when it is pressed. It is not necessary the cut be the same thickness around its circumference. The headtube above is completely faced. Notice the machining at the to position.
The paint indicates a low spot, yet there is still cleanly machined metal all the way around the cut. It can happen that the facing tool will skip or chatter over a cutting surface.
Chatter can often be controlled by changing turning speed and pressure. The type and hardness of the material will also affect the amount of chatter. After facing, light spins on the facer will minimize chatter. Even if the headtube appears to have slight chatter marks, these are all the same height, and typically do not effect the quality of the machining. The headtube is still squared even with chatter marks. The headset cup has a slightly larger diameter than the head tube inside diameter.
Generally, differences of 0. If the pressed cup is more than 0. If the press fit difference is from 0mm to 0. It may be possible to find a different headset cup that is slightly larger to improve the press fit. Otherwise, a strong grade of bearing retaining compound is recommended. If the headset cup is actually smaller than the inside diameter of the head tube, a new headset with a larger diameter is recommended.
The HTR-1 comes with a The optional larger The pilots may be used in place of the reamer if the inside diameter requires no reaming. Reaming is only required if the press fit diameter difference is too great. To install either the reamer or pilot, remove the retaining nut. Install the reamer or pilot.
Replace the retaining nut and tighten fully. The retaining nut must be secure to keep the reamer from spinning. There are now available headset cups have a relatively long insertion into the headtube.
The headtube may require further reaming to allow these headsets to fit. The Head Tube Reamer Extension will allow for reaming down to just over one-inch 26mm.
Check with frame manufacturer if in doubt about frame integrity. The Internal Headsets uses a pressed cup inside the frame. The cups hold the bearings and the entire headset has a low-profile look. The headtube ID in nominally 44mm. The pilot is used with the XL to face the headtube. At this time there is no reamer for this standard.
The Integrated System without cups comes in different standards and dimensions. This is a nominal ID of 41mm, with a degree bearing seat. Do not use the cutters to change a bicycle to a different standard.
The S comes as a pair, with an upper and lower cutter. The upper cutter takes a shallow cut for the upper part of the head tube. The lower cutter is a deeper cut. It is important that the cutters be used in the correct part of the frame.
Only one cutter is installed and used on the HTR-1 at a time. NOTE : As with any facing tool, inspect for clearance to all frame parts such as at downtube.
There is a practical test of the bike to determine the need for machining. Place a bearing into the headtube. The bearing is a loose slip fit, and there will be some motion or rocking in the bearing. Place a thumb on either side of the bearing and press alternatively downward to judge the amount of play. Move to front and back edge of bearing and repeat the test.
