    Wow, they must be really nice springs

    The price is double from the DSP-spring that they used to offer. Maybe they have better rust-free performance?

    Actually a few differences from the old Diverse springs. The new springs are shot peened and clear coated with a UV protectant that wont rust or oxidize. The old springs had no coating at all. New sizes and diameters are in the works as well as fork springs. Compared to Renton Springs, the Kronos springs are for the most part, less expensive and the renton springs dont have any coating.

    Same here, but I just picked up some UV protectant from Home Depot to coat my watch in - last thing I want is a rusty ti watch.

    yes, they do but it isn't an issue with titanium which is why no one coats their ti frames or springs with anything. aluminum oxidizes as well, but it's clear and when formed protects the aluminum form oxygen and further corrosion. ti is the same at room temperatures. my comment was facetious and poking fun at your reasoning that the kronos spring is somehow superior to diverse because it has a uv coating

    Like aluminium and magnesium metal surfaces, titanium metal and alloy surfaces oxidize immediately when they are exposed to air. Titanium readily reacts with oxygen at 1,200 C (2,190 F) in air, and at 610 C (1,130 F) in pure oxygen, forming titanium dioxide.[7] However, it is slow to react with water and air, because it forms a passive and protective oxide coating that protects it from further reaction.[2] When it first forms, this protective layer is only 12 nm thick but continues to slowly grow; reaching a thickness of 25 nm in four years

    so unless they coat it before the spring is exposed to oxygen, the uv coating is worthless on the spring. maybe it's a great marketing plug, but it does nothing for the spring itself.

    Like stainless steels, it is dependent upon an oxide film for its corrosion resistance. Therefore, it performs best in oxidizing media such as hot nitric acid. The oxide film formed on titanium is more protective than that on stainless steel, and it often performs well in media that cause pitting and crevice corrosion in the latter (e.g., seawater, wet chlorine, organic chlorides).

    And, as usual, the nuclear over-reactors fire up on the most irrelevant and inconsequential details, totally ignoring what's important:

    THEY HAVE SPRINGS THAT WILL FIT IN THE SIZE/RATE I NEED.

    The price is the same w/ shipping&tax as the perpetually out of stock Renton springs - the only others I could find. All the rest of the whining and ranting cannot trump this simple fact.
    Nice KOM, sorry about your penis.
