    How much spoke head clearance is required?

    I can't seem to find anything, but that it should be a positive number.

    A set of 28h rims I am about to build up will have 1.2mm of clearance with a 3x lacing. Is that enough clearance?

    2x will give me 5.8mm

    Thank you

    No idea what you're talking about.

    Why don't you use spoke length calculator and determine the spoke size you need? Post the numbers here, we'll help you.

    I did use a calculator, hence how I know I have 1.2 mm of clearance. It is how much room there is between the spoke crossing over the first cross spoke head.

    No thread should be showing and no spokes should be sticking out on the other end.

    Use this link, its far less confusing and straight to the point:

    I don't think we are on the same page. I am referring to when a spoke crosses another spoke it can cover up the spoke head making removing a broken spoke a PITA. I am not talking about spoke thread length. There is nothing confusing about Roger's calculator that I posted

    I would never use "spoke head clearance" as the guide whether to do 2x or 3x.

    In all normal hubs you'll have no issues removing spoke, unless you're lacing 24h rims with 3x, but in all other cases don't overthink it.

    This is why 2x is commonly used with 28 or 24h hubs. My thought is you'll be ok, but I don't know how much clearance you need? I'm not very familiar with that calculator or the measurement in general.

    I just laced my first 28h rear wheel 3x and it worked out ok. I wasn't sure it was going to work once I had the wheel laced and no tension on it, just looking at it. Once I got some tension on the spokes I knew I was safe.

    If you haven't ordered spokes yet you can go 2x to be safe, otherwise it may be a bit of a roll of the dice, but like I said I think your OK.

    Stop asking how much it weighs and just go ride it.

    I'd go 2x just to reduce the spoke angle, but that's just my preference.

    It ain't supposed to be easy.

    I am fine with going 2x. Actually find it interesting that both replies so far have been for 2x. Usually I feel like everyone is screaming 3x is the only bestes way

    As long as the clearance is positive it will be fine. Take a look at the help page (in the spoke length data, click the heading "Spoke head clearance").

    The spoke entry angle is okay too, so no problem with 28h 3x,

    Also, you have selected a 2mm diameter spoke. Are you sure that's correct? For more info, click the heading"Spoke dia." to make sure.

    Roger,

    Wow, I feel like an idiot. I have been using your calculator for a while and never knew you could click on the different headings. And no, 2.0 was not correct. I will be using cx-rays so 1.5. I thought the spoke diameter was for the ends, but it is the middle section?
