Spoke lengths

[Macmania]

Sure this has been covered before but I can't find any info anywhere 

Okay, going to be building a couple of set of wheels in the next few weeks and just want to clarify what spokes I should be looking at purchasing.

Set 1.  20x 1 3/8 laced to Large Flange hubs.

Set 2. 20x 1.75 laced to Large Flange hubs.

Thanks in advance.

Thanks for the info but i'm still unsure about the 20x 1 3/8 laced to Large Flange hubs

Download this handy Excel spread sheet instead ... it uses a huge database of rims and hubs to get the right spoke length
