rnhood wrote:So "effettomariposa", a couple elementary questions for you:
1. Do you normally recommend pre-filling the tubular tires with Caffelatex or, just carrying the on-road pressurized bottle?
2. If pre-filled, does this affect the ride to any degree, or the weight (again, to any significant degree)?
Another take on the answer to these...
I have deep rims = valve extenders, so I can't add (in my case) Stans after a puncture, so I have pre-filled. I carry a can of Pit-Stop as a back-up.
Well, for each time you add 1g of a substance, you add 1g of weight to your wheels - simple. If you can live with that or not is up to you. A friend of mine can not because as he say: ''There is no way extra rotational mass can make me faster'', and he is right. My priorities are different because I also train with my tubular wheels, so I don't mind sacrificing a little weight for the extra puncture resistance. As mentioned above I had two flats on my rear this season, Stans sealed them both and I still run the tubular without any problems/leaks.
