Hi, have on the comparative test in the last "bike" issue to buy the "Test Winner" F100 .... After the third stage of the CRAFT BIKE Transalp 2012, I am of the opinion that this is a super lubricant for fair-weather riders. the low dirt adhesion, which was touted is given because there is nothing to complain about .... However, the lubricated chain comes a few times with water and stone dust in touch - (which at Alpine crossings happens to be the case) - flies the lubricating effect too quickly .... Also applying to the chain designed rather wasteful since the spraying much bib, and then the flashing off even part "disappear" Our before each stage freshly lubricated chains often rattled after the first half of most stages. I definitely recommend the sprayed "excess" oil after venting not wipe, then extended in any case, the lubricating effect My conclusion: for standard, road or tour may be in order, the product, My claim as a mountain biker could not be satisfied here!
