This thread may be more appropriate somewhere else, but this is the forum that I follow most, so: This question might seem a little goofy, but I'm actually considering doing my first wheel build and I'm unclear about the different multiples of rim hole combination's. I have a set of Mavic Open Pro 36H rims and I'm looking for a set of 105 or Ultegra hubs to go on a road race frame. But I've noticed that most race bikes have a combination 0f 32-36, 28-32 or even less on the modern bikes. Is there a reason why you would want less spokes up front other than not needing the added strength as much and therefore added weight? Or is it more for the looks?
