I am going to be building a new set of wheels in the near future. I am very budget minded, so I don't want anyone chiming in with a "get some Edge tubs" post or anything. Good, sound, and budget focused advice definitely needed. Ok, here goes.
I am 165-175 lb (75-80kg) depending on what I've eaten on any particular day
I am considering Stan's Alpha 340's, Either the BikeHubStore SuperLight or Rotaz hubs in 24/28 spoke count, and Sapim Laser spokes, lacing 2x up front, 2x DS and radial NDS rear.
1) Lightweight (duh) - I am currently riding on a Neuvation R28Aero4 wheelset. While very cool looking, they are a bit heavy at 18xxg for the set. I've also read on some durability issues with them, so part of my reasoning for the new build is to have another set to switch out/replace them in the event of any problems.
2) Durability - I ride some roads which I would not consider well maintained, and the R28s spoke count is 16/20. I assume the low spoke count requires more loading per spoke, and therefore places more stress at each of the mounting points on the rim than on a higher spoke count. The R28s may hold up, may not. Regardless, Neuvation is 15 miles away from me and they are under warranty, so I am not super worried about that, but if I build my own set, I figure a higher spoke count of 24/28 will be safer (with regards to durability/life), and I can get away with using a lighter Sapim Lasers.
3) Vertical Compliance - I would venture to guess that a higher count of lighter gauge spokes at a lower tension offer a little more elasticity than a lower count, higher tension setup. I am not really sure to be honest, and always appreciate good advice and informed opinions from experienced wheel builders.
4) Lateral Stiffness - I've been reading on WW about what makes a stiff wheel - Stiff rim, Flange diameter and offset from the hub center, and some bantering about spoke tension/ stiffness. I know the difference between tensile and ultimate strength, and I'd rather not approach the ultimate strength of any spoke, which means not allowing any individual spoke to reach the upper limit of its tensile strength. I reason that the higher spoke count would lower the overall tension on individual spokes, while more evenly distributing the tension on the rim and hub, making the overall stress on the wheel lower yet retaining a good amount of lateral stiffness. Am I way off here? I am not an extreme weight weenie, and am willing to trade a marginal amount of weight via a higher spoke count in exchange for a longer lasting wheel. Besides, the rim/tire/tube are the most important factors with respect to rotational mass, so the advantages of a couple extra spokes outweigh the weight penalty IMO.
So, that being said - Does the combo I listed look to satisfy my goals? With regards to my weight, will I have a problem using the Lasers and the Alpha 340s?
