  1. 24" Surly Large Marge rims arrived yesterday, and I'm happy to announce
    that they passed our QC. They should be in stock today or early next
    week at the latest.

    Last night, I laced one onto a Suzue hub and installed it on my first
    homebuilt frame....made from a Surly 1x1 fork. I'm using an Intense DH
    24 x 3.0 tire.

    I don't have much time on it....just a few laps around the block and
    some messing around in the yard, but I already prefer the wheel over the
    24" Alex/Gazz wheel I had been riding in that frame. The increased
    lateral stability is the most notable difference. The extra float and
    traction will, of course, be there when I ride on loose and/or wet
    surfaces.

    Cheers,

    Dave

  3. Wonder if the LM/Intense or Gaz combo would fit on a Lightrider or KH 24
    frame???

  4. Can we get a measurement of the width of your tire while inflated in
    that rim?
    (inches please 😄 )

    I may have to whip out the charge card ...

  5. Dave, what is the effect, in your opinion, of the wide spoke spacing on
    the LM rim, given the fairly narrow flange width of the Profile hub and
    other splined hubs that we use for muni?
    In other words, it seems there isn't much spoke "angle" from the hub
    flange to the rim, as the spokes go almost vertical when viewed from the
    front or rear.

    Would it benefit wheel strength any to cross-lace the spokes to go from
    the left flange to the right spoke holes in the rim, and vice-versa??

  6. Tire width measurement done at 15psi. Luddites will have to do the
    metric-to-inch conversion.

    Intense DH 3.0: Casing 74mm
    Tread 73mm

    Nokian Gazz 3.0: Casing 81mm
    Tread 71mm

    Regarding spoke angle. No failures on the 26" Large Marge, yet. The
    24" will be stronger....more acute spoke angle relative to the hub axis.
    A well-built, properly-tensioned Large Marge wheel will stay as true as
    anything else available on the market.

    Cross-lacing won't work. The eyelets won't allow it. Even if it was
    possible...1) It's not necessary 2) It would put too much stress on
    the hub flanges and the spoke elbows...where most spokes break.

    Joe and I have been using 32-hole 26" LM rims laced to 48-hole Suzue
    hubs since early 2004 (I didn't have any 36-hole LM prototypes at the
    time I built the wheels). My wheel (now, on the Goiter) is still
    perfectly true. Joe will have to comment on his wheel performance.

  7. It seems like the wheel would also roll flatter on the ground, since the
    sidwealls are spread out farther, allowing for a more grippy, smoother
    ride. Is that the case?

  8. The 24" 36 hole DH rims are in stock now, as well as the 26" rims, and I
    am taking orders for wheels using KH, Profile, Suzue, or UDC hubs.

    Last time I talked with Surly they said there is currently nothing
    planned for a 24" version.

    No offense was intended. I'm a luddite in many regards. Should have
    used a smilie, I guess.

    Nor was your request annoying. But, I use metric measurements in my
    professional and personal work whenever it's appropriate. Most of the
    world, outside of the USA, does. So, I make a point to reinforce the
    use of a more universal (and logical) measurement system. Of course, I
    did use "psi" as my unit of pressure. I'm guessing most of you don't
    think in terms of "bar" or "kg/cm2" units. Or do you?

    Dave

    Here's a pic of the Nokian on a proto rim.

    The Endomorph is only available in the 26" size.

    A high-volume 24" Surly tire will probably be introduced in the future,
    but I'm not going to give specifics at this time. We still have to use
    designed-for-DH tires for a while.

    Tires are very expensive to produce....especially oddball stuff like the
    Endomorph. No tooling exists for tires this size. Special machines and
    unique moulds have to be built to make it all happen. So, we can't pump
    out different sizes and tread patterns as fast as we'd like to.

    The tire does flatten out and should give you more traction compared to
    a tire on a narrower rim at the same pressure. Smoother? That's hard
    to quantify. I don't notice much of a difference in smoothness.

  17. So is anyone actually making 3.7" frames? having beaten the [censored] out of
    everything i've ridden so far (cotter-less cranks and 10ft drops dont
    necissarily go well together) i'm in desperate need of upgrades 😄

    damn, im now im stuck in the middle....cool that that the rim is in both
    sizes though. A 26" tyre would be so fast but a 24" Endo would be the
    most beloved in the MUni world since its more "all around"

    This happened before with the 3.0 tyre's......back in 2000 there were
    not any high production frames that fit a 3.0 and look at it now.

    heres to hoping it does come out.

  20. SurlyDave --

    Your photo shows a machined brake track, but the distributor's website
    states "Disk brake only", despite showing a silver sidewall in the (one)
    photo. Does the 24" have a machined brake track? If so, is that true
    for all the versions of the 24"?

    Thanks in advance!
