For Sale Syncros stem cap reproduction

They won’t crack if they are not used for the initial loading of the bearings.

- use a different stem cap to load the bearings
- tighten the steerer clamp on the stem
- remove wrong stem cap and fit repro version
Same principle with the originals too ;-) especially if the headset, stem, steerer isn't new.
 
We experimented with different variations (which mean nothing to me). Think around 10 were tried. And still experimenting today

Some failed by cracking , and some failed by being too soft.

To be on the safe side I’d recommend preloading with a metal cap and then add this decorative cap on afterwards.

However they do work to preload the bearings fine. If you continue to tighten them beyond that then of course they break. But the standard plastic one would do the same too.

After a few hours of printing and testing we are happy with the final version.

You can tighten a headset way beyond what you would to preload bearings (to the point the headset locks) without the top cap breaking.

However as a disclaimer I’d say that you need to use a metal cap to set the preload and then replace with this decorative top cap to finish.

Printing another 15 off today so they are going to be available from tomorrow
 
Final version is done.

Reproduction Syncros Cattlehead 1 1/8 top caps.

These are 3d printed in black with no logos and are to suit angled Syncros stems only.

They have been tested by myself to destruction to make sure they are strong enough to preload a headset. This involved tightening the headset until the bearings won’t spin which is way beyond what anyone will need to do to preload their bearings.

However as a disclaimer I’m selling them as decorative pieces to be used once the headset has been preloaded ( and stem clamped in place) using a metal top cap since I know how heavy handed some folk are.

£10 each. Price inc UK postage. Payment by paypal gift or fees covered please.
