@danfuerthgillis44833 жыл бұрын
Many road bikes do not use the small 5 mm spacer under the top cap. The reason is the expander plug is put in and the extension bar then slides up 3-4 mm pass the top of the plug metal head. This allows for the bottom of the expander plug to protect the carbon steerer on the bottom and top bolts of the extension bar. Always use a 4 cm expander plug this way you can the 5 mm spacer, a smaller expander plug is really for slammed stems, also check the inside of the extension bar and make sure it is smooth and has no rough edges on the clamp hole area. I have seen tons of high end road bikes where there is a 4 mm gap on top and the cap tightens with no spacer underneath it.

Installation in written form: Set bike on ground, ensure full stack is entirely seated. Set stem height. Stem or spacers should be ~3mm above the top of the steerer tube. (For carbon forks, steerer tube MUST go entirely through stem. Use spacer on top to get the 3mm) Grease on topcap bolt, install. Snug down, tune later. (Carbon bars - put on assembly compound) Grease OR threadlocker on faceplate bolts. Thread in bolts. Tighten lightly but evenly according to stem design. Set bar roll, center bars. Fully tighten faceplate bolts (4-6Nm) in X pattern. Snug topcap down until there is slight resistance. Bars should turn with almost no resistance. If there is, loosen by 1/8 turn at a time. Straighten handlebars to fork. Snug pinch bolts. Test for play in headset by holding front brake and rocking forward and backward. Feel for play at headset. If there is play, loosen pinch bolts, tighten topcap 1/8 turn, retighten pinch bolts and try again. Tighten pinch bolts (4-6Nm).

Question! At 7:02, the video has us adjust the top cap until there is little resistance. Then, at 7:38 we test the headset adjustment looking for play and if we have play, then we tighten it down a little more. Won't the tightening of the top cap to prevent rocking then increase the rotation resistance of the handlebars? It seems like the action to prevent one issue is simply going to cause a second issue.
@parktool16 күн бұрын
You should be able to eliminate play without excessive resistance. It is preloading the bearing and is necessary to do. A loose headset can ruin a headset or in some cases a bike.

The reason for the stem or spacer to be above the steer tube is to allow the top cap to do is job. The top caps job is to pre load the headset bearings to get rid of any potential for play. If the spacer or stem is below the steerer then it will be near impossible to get a correct headset adjustment.

Maybe a stupid question at 5:59: Are you applying SAC-2 fibre grip to the bolts (or is that your PPL-1 grease)? Wouldn't this increase the friction resulting in less axial tension? Meaning you need more torque to achieve the same tension - which is what you wouldn't want if one of the components is carbon? I thought SAC-2 would only be applied to clamp surfaces.
@parktool3 жыл бұрын
That is PPL-1 and not SAC-2 being applied to the bolts. Do not use SAC-2 for threaded applications.

If the steerer is metal then the star nut has gone bad. Unfortunately it may be best to drill the head of the bolt out and then use a punch to pound the star nut out the bottom and replace.
