cut out head set spacers?

[02GF74]

what do folks think of the cut out type headset spacers?

they must be the lightest available (apart from maybe the polycarbonate type) but I wouldn't use them as they do not look as neat and I would be worried, probably unecessaril,y that they would let water and muck into the headset bearings.

I use the Cane Creek AER Spacers on the weight weenie build, depending on the headset there is a risk of water getting in.

I use ones like this.

How about ones cut out longitudinally?

I wouldn't be super keen to use the ones originally suggested but really like BBB Ultraspace carbon spacers. For all intents and purposes the same as a normal spacer (i.e. work the same and keep water out) but at a fraction of even a normal light carbon spacer. Cheap too!

You're less worried about using a spacer like in your first post that appears to be pretty poor compared to a simple, perfectly functional delrin spacer?


Anyway, the actual AER spacers are good, but if you're after something that's filled in, POP make some light spacers, but Tune magnesium seem to be some of the lightest:

I would be surprised if the milled out carbon spacers that myself and DanW posted were not the lightest spacers available.

Well then, be surprised - Extralite delrin and POP aluminum are almost the same weight. Tune magnesium, Point1 and HiTeMP42 aluminum are lighter. But hey, we're arguing over a gram here... errr less than a gram.

[DanW]

The BBB I posted are the lightest I could find and I did a lot of research on that. But as you say it is only a g or so depending on the amount of stack you use The main draw for me is that the BBB are not only the lightest but £8 for a 40mm combo IIRC

How about some actual weights, taken at the same time using the same scale.

5mm:
Tune Magnesium: 1.3gr
Point1, 1.4 gr
Parts of Passion, 1.5gr
Extralite, 1.9gr
Cane Creek AER, 2.0gr
Kcnc hollow alloy, 2.6gr
Std carbon, 2.7gr

10mm:
Point1, 2.3gr
Tune Mag: 2.4gr
Parts of passion 3.1gr
Extralite, 3.4gr
Cane Creek Aer, 3.9gr
Std carbon, 4.2gr
Kcnc hollow alloy, 5.5gr

meh... Don't believe you

No BBB carbon or FSA carbon.......
