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

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 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.

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
