    With everything trending towards "flow" trails......BB can be low since there are not rocks/chunk.

    The problem is, we don't only ride "flow" trails.

    I will never buy a bike again with a BB lower than 13.5. I run 170 cranks too. Most of my PS have been on techy climbs , one pitched me off a cliff in Sedona. Have had 3 nasty ps crashes that I was just lucky with. One descending Sunset at Mt. Lowe, one on Cold Springs in S. B. and one solo on Exploration, SCARY CHIT! The Cold Springs and Exploration P. S. we're because of a rear shock that had gone defective and was partially stuck down making BB height a half in. shorter! Took two crashes for me to figure that one out. My Reign was 13 in. and was whacking pedals all the time. I put 27.5 wheels on it and it helped a bit but still not good. It's basically what you are used to. If you have been riding a 13.5 and go to a 13 or lower there will be a learning curve. Hopefully not a painful one. Bottom line if you like climbing and descending in the rocks BEEE CAREFULL WITH A LOW BB.

    Strikes...I noticed more issue since going with longer crank spindles. Kind of adjusted to it I think.

    But in SoCal I have more issue with rocks kicking up into my bike and legs than pedal strikes. Chiquito being the exception.

    Part of the problem is that the word "theory" means something very different in lay language than it does in science: A scientific theory is an explanation of some aspect of the natural world that has been substantiated through repeated experiments or testing. But to the average Jane or Joe, a theory is just an idea that lives in someone's head, rather than an explanation rooted in experiment and testing.


    "A word like 'theory' is a technical scientific term," said Michael Fayer, a chemist at Stanford University. "The fact that many people understand its scientific meaning incorrectly does not mean we should stop using it. It means we need better scientific education."

    Definition of theory
    plural theories
    1: a plausible or scientifically acceptable general principle or body of principles offered to explain phenomena
    • the wave theory of light
    2a : a belief, policy, or procedure proposed or followed as the basis of action
    • her method is based on the theory that all children want to learn
    b : an ideal or hypothetical set of facts, principles, or circumstances —often used in the phrase in theory
    • in theory, we have always advocated freedom for all
    : a hypothesis assumed for the sake of argument or investigation
    b : an unproved assumption : conjecture
    c : a body of theorems presenting a concise systematic view of a subject

    by Merriam Webster

    There are a few Scientists around here who will gladly point out what a "theory" is.

    Best way to get the right answer on the web is to post the wrong answer....

    I have a theory that you and I just agreed, right? Non of the definitions above point to the word “fact”.

    Man! I love this place!

    Says the guy who is benefitting from Magnetic resonance theory, X-ray theory, and aerodynamic theory...

    The "facts" are in the experimentation that supports the theory.

    Then they should just grow a pair and call it “Fact”. But, they can’t.

    Not really, but I'm bored trolling so I'll be heading to the garage soon to get factually waked and baked using coffee and cannabis theory!

    Fact: Human induced climate change is real.
    Theory: Human induced climate change is bad.
    If you live on an atoll it’s a fact. If you’re Russian it isn’t.

    Close...climate change is real, and constant, and has been for over 4 billion years. Human induced is still an open question. After all, Mars is also warming and there are no primates of any stripe there.

    Facts are dependent on the state of the observer, and evolve over time. It was once a fact that the earth was round, and everything in the universe revolved around our rock.


    Edit: Apparently it was once a fact that 15" bottom brackets were the best! It was a fact because Santa Cruz said so. :stop:



    Just stirrin' the pot. :whistling:

    Likely...

    Of course, since the ice age ended the temperature had nowhere to go but up. o_O

    It slays me they completely...utterly...ignore little things like Pinatubo, Unpronounceable Mexican Volcano, Kilauea for the last how many years...

    I'm not saying an industrial society does not contribute gunk to the atmosphere or that it would not be a good idea to reduce those emissions. But let's have a little sanity. What we put out is nothing compared to tectonic processes.

    And cows.

    So if you get 95% on a test, it is "likely" an A grade was awarded.
    Hmmmm

    Unless it's on a curve and certain data points are ignored.

    Hmmmm.

    I’m close to that. My only dilemma with it is when I stall out on steep/chunky climbs along exposure. My tippie toes barely touch the ground, and I’m at the mercy of misfortune.ED243C2B-F284-499B-9F33-54A92F57C3CC.jpeg062C9496-E29F-4777-9A46-0A825090E99A.jpeg
