The Un-Official Guide To Fixing Headset Play - Please Add Your Advice Here Hey Everyone,

I wanted to create a guide to help troubleshoot headset play regardless of bike brand. By no means am I an expert, and I hope others can add to this thread. Please understand this guide/thread isn't intended for airing our bike brand grievances or calling out user errors. Ultimately we all just want our bikes to work as intended.

Common Reasons For Headset Play

1. Steerer/Fork isn't cut low enough, or an extra spacer is required above the stem to properly compress the top cap. When initially cutting the steer tube, an extra 2-4mm below the cut line needs to be accounted for in order for the top cap to recess properly.

2. The headset bearing (upper or lower) doesn't sit inside the head tube cup snug enough (laterally, front to back). Velobuild, for example, provides 52mm diameter headset bearings. Other headsets sold online or for other bike brands may only be 51.8mm diameter. That 0.2mm is the difference between a snug fit or loose headset. If your bearings are loose this will always cause play. You can add a couple layers of tape inside the bearing cup to prevent the bearing from moving around. Or just buy a new 52mm headset.

3. The top headset bearing is recessed too far into the head tube cup, causing the headset cover to rub on the frame, preventing the complete headset stack to properly compress. If this is the case you will need a thicker headset bearing (7mm, 7.5mm or 8mm thick) or a thicker c-ring so that it sits flush with the top of the headset opening on the frame, thus preventing the headset cover from rubbing the frame. EDIT: Another resolution is adding some micro spacers between the c-ring and top cap.

4. The upper and lower headset bearings are installed in reverse. Some bikes (like Yoeleo's recent G21 gravel bike) provide a set of headset bearings, with one of the two bearings being slightly thicker than the other. The thicker of the two bearings needs to be installed on top of the head tube, and the thinner bearing on the bottom. If these two bearings are installed in reverse order then...see Common Issue #3

It is critical to do a dry run of installing the crown race, headset bearings, c-ring, headset cap, stem/cockpit, and any additional spacers before actually proceeding to building up the bike. Also be sure to compare and inspect the two headset bearings to confirm they are in fact the same size and thickness.

Yishun R086-D Aero Road I just ordered a R086-D. Figured a new thread would be easier, to avoid confusing the with the R068-D. With such a long and low geometry I should not have any problems mirroring the setup to my Allez Sprint or Winspace T1500.

https://www.yishunbike.com/product/r086-daero-road/

DETAILS
Frame: R086-D Aero Road frameset
Size: 540
ST062 Stem: 130mm*
HB058 Handlebar: 40cm*
*Both the stem and handlebar allow for internal cable routing
Includes bearings, spacers, hangers, and thru-axles, etc

Yishun only offers custom painting services for orders of 4 or more, so only matte black is offered. Totally fine by me. Kitty, their sales rep, responded to all of my emails within 24 hours. The transaction was super easy.

One hilarious quirk, which I couldn't tell if he/she was bluffing, was the comment below:
"Since we're going to send non-selling components parts to our german warehouse next monday. If you need the frameset, pls confirm the order this week."

Whether or not this was a simply a sales tactic or them being truthful, I'm not one to waste people's time (or mine) when it comes to pulling the trigger on a frame purchase. I'll report back in a few weeks when the frame arrives.

Re: How do high SKU Chinese Carbon Manufacturers work? I don't believe that Chinese companies operate the same way western companies do.   As I understand it, many Chinese manufacturing companies really don't "own" their manufacturing facilities. Larger holding companies, that have all of the equipment and resources often make a small companies products.   They pool resources with other parallel/compatible products.  Carbon bike parts could be made in the same facilities as carbon fishing poles, or other recreation parts.   I understand that they often get funding from the government to develop their products.  If they require more tooling /molds like frames and rims, there are a pool of "experts" that help them create what is needed to manufacture their part.   They don't operate under a cutthroat open system where competition rules and the big companies chew up the small or purchase them if they become a threat.  They help each other out for the good of all.   (But there is a lot of pressure for them to be successful in their field of business.)

It has been a few years since I read up on how their manufacturing businesses work. You have to shift your perspective in that a "small/medium business operator" there don't have to make "big cash" to stay in business.  As long as they contribute to China's success, they are considered a value to their system.  They still have to earn enough to feed their family and make sure their employees do well too.
