    which steel fork?

    Guys, other than the obvious what are the ride differences between a lugged-crown-curved-blades disc fork and a unicrown-straight-blade disc fork?

    to be specific the Soma fork for the Double Cross. they both have the same rake of 44 mm. and ATC 400 mm.

    is one more rigid than the other, are they laterally the same?

    thanks for the help.

    Soma Wolverine Review
    I'll save everyone 45 min. of reading and post the two relevant paragraphs.

    "One flex issue that did present as more of an issue was the shuddering from the front fork under hard braking. It was only apparent when really grabbing a fistful of front brake, but the skinny fork legs flexing back and fourth wasnít confidence inspiring.

    However, this isnít necessarily a downside, but more of a trade-off. Soma Fabrications do offer burlier straight-blade forks for their 29er hardtails, which are designed for faster and harder trail riding. The beefier forks tend to transmit a lot more feedback through to the handlebars though, and so the decision was made at Somaís end to spec the Wolverine with the swept fork to help provide additional compliance to the front end. The design certainly works, and combined with the slender back end, the Wolverine offers an incredibly comfortable ride both on and off the road."

    my thoughts were along the same line; that the the skinnier forks will be more supple than the straight blade. these differences are more obvious at higher speeds in rougher trails.

    you definitely should not fear the fore/aft flex of a good rigid fork. that is where it gets any smoothness it is going to have. my waltfork flexes like crazy when flying downhill; doesn't effect the handling at all that i can tell but definitely makes fora a much more forgiving ride than the karate monkey fork it replaced which was much stiffer in that department...

    Just a thought, but riding on a stiff fork would seem like the whole point of riding a rigid bike. Fore/aft flex seems like it would be a bad thing!
    If you want smooth, you can use a very "stiff" suspension fork that only allows movement in prescribed paths, right?

    wrong. all wrong.

    rigid does not have to be stiff or vice versa. thats how compliance is engineered into a rigid fork.

    even a stiff suspension fork is nowhere near the same thing as a rigid fork, and defeats the purpose.
