To be clear, and at the risk of being presumptuous, I believe my Belgian brother is referring to sealant to use in an emergency and is not suggesting that you pre-load a good tubular with sealant. I know the Vittorias are heavier, but I like them.
Looking forward to the tire choices today at E3 Harelbeke! Are you going, Frank?
Yes. Either as an emergency repair on the road although I much prefer to mount a spare, pre-glued tub, or as a repair at home which works fine for small punctures.
I must have a bunch of these brass Vittoria extenders in my storage room in the basement. I switched to the otherwise identical aluminium ones as they're lighter in can be had in all kinds of lengths.
Schwalbe also offers them in 28mm length (I think) which is just enough for a 50mm deep rim a la Bora.
Maybe Conti also offers the same alu ones, not sure. They do offer the same ones as Vittoria does though.
The Tufo style extenders are the best IMHO, I do not even use plumber's tape as they just refuse to leak.
Geoff, I'll be watching the E3 Harelbeke from the comfort of my chair. It's nearly freezing point here with a pretty strong north-eastern wind.
I prefer brass nipples, too
Funny how tastes can differ, huh?
@OhPinchy: standard stem lengths are commonly either 36mm or 42mm. Vittoria uses 42mm stem IIRC.
For a Bora wheel (50mm) and using Veloflex tyres (36mm stem) I use a 28mm alu extender (Schwalbe or Tufo, they are the same anyhow). 36 + 28 = 64 mm which is ample for a pumphead.
The only disadvantage of an overly long extender is that it adds weight and can potentially unbalance the dynamic balance of the wheel.
