    Fork decisions cromoto grande vs. chinese carbon

    Apparently the two forks I already have are too short in the steerer. I did the math on the stack and no dice.

    So which fork do I get? I can pick up a used cromoto grande up off of ebay for around $125, maybe less if I am patient. Some decent looking, tapered, thru axle chinese carbon forks are going for about $132.

    What should I get for the carbon superfly Ss that will be here next week? I am 147 lbs on the scale just this morning. I dream of being a weight weenie but I am too poor for that. I value reliabilty but am drawn to the lower weight and look of the carbon.

    Thoughts?

    The cromoto is nice, the one I have has reversed drop outs, cable guides, rack mounts, I think it's good for 180mm of rotor. I trust it to hold my front end together when I'm bumping around. You can save weight on the front end with a good wheel/tire choice, then stem/bar and silicone grips. I wouldn't focus on bike weight until it looks like something is an obstacle to the podium. Work on your skills and strength, that's what moves the bike.

    I have a cromoto that I just got and used a tiny bit on my carve. Id use it but the steerer is like 2mm too short I think. It's definitley beefy compared to the chisel fork that was on it before.

    Just seems weird putting a steel fork on a full carbon bike.

    If there's one place to go with cheap carbon, it's definitely the fork! I mean, it's still carbon, amirite?

    Doing more research....

    all the aluminum steerer carbon legged forks such as eXotic and carver weigh in over 900g - just 200g ish from a cromoto

    the chinese full carbon deals range from 510-700g - so 1/2 - 3/4 of a cromoto

    To me it doesn't make sense to go carbon unless it's full carbon. The chinese carbon is very polarizing. It seems some are in the "everything is made in china" camp and others in the "if it's cheap, it will break" camp.

    But the cromoto will look ridiculous on this frame :-(

    Anyone voting for the chinese carbon...or even better have a 15mm T/A fork laying around for me to buy with a lot of steerer?

    You're worrying about 2mm (so 0.080") steerer length? Or just use a stem that has slightly less stack height.

    On recalculation (see below) I am about 8mm off at best. :-(

    Part of the issue is the need for a external bearing cup for the bottom on the superfly so I can use a tapered fork. This adds quite a bit of stack.
    Here is what I calculated, let me know if you think I might be able to use what I have...

    Bottom Cup (external) 12mm
    Head Tube 117.5 mm
    Top Assembly 8mm (if I can use the zs44 short top assembly)
    Stems are all 38 - 39.75 mm

    total = 177mm or 6.97 inches

    Current Forks:
    Manitou Marvel LTD 100mm fork - 6.565 inches or 166.75mm
    Salsa CroMoto Grande Rigid - 6.75 inches 171.5mm

    So currently I am 8.5mm off from the minimum.

    With a 38mm stem you end up with a total of 175.5mm - steerer on the Salsa's is 171.5mm which gives you 4mm clear at the top of the stem. Personally, I'd happily run with that as long as the upper pinch bolt is below the top of the steerer tube, which I imagine it will be?

    I'll certainly give it a try first.

    The question still remains assuming it will not be good enough.

    Thanks for the thought, at least there is a chance I won't have to go fork shopping for a while.

    Assemble it all, preload it and tighten the steerer and then remove the top preload cap and measure it. Anything up to 4mm will be fine IMHO.
