A few things to consider about low spoke count wheels, the spokes are thick and heavier then standard spokes, the rims are heavier and have a larger cross section then rims used on standard wheels, they are more difficult to take care of and true by the home mechanic, and finally, they are not as durable and often weigh more then a 32 spoke cross three wheel. I think, and this is just my opinion based on my experience, I have built over 200 wheelsets over the years of various types and configurations, when building a set of wheels I try to take the following into consideration.
c. potential wheel loading
d. type of riding to be done on the wheel
e. road condition where the wheel will be generally ridden
f. what the customer wants.
for a light rider, I like a wheelset built as follows:
shimano ultegra hubs, they are the benchmark in the industry for value and dependability, they are clean looking and roll smoothly.
14/15 guage DT butted stainless steel spokes, they present a small weight savings with the 15 guage center sections and the durability of a 14 guage spoke at the bend and the threaded sections where breaking usually occurs.
nichol plated brass nipples for durability and the ability to build to a higher spoke tension than alloy nipples.
I build the rear wheel in a cross three pattern for durability under load and torque input and the front you can do nicely with a cross two build because torque input is not an issue.
You can do unique things with rim colors and spoke colors to make your wheels stand out from the original equipment wheels that are on most bikes, on the wheels I build, all of the pulling spokes are on the outside on the last cross so they pull the spoke bundle in when torque is applied, if you look through the valve hole in the rim with the tire removed, you can read the hub lable, the labeling on both hubs and rims are in the same orientation when installed on the bike, the spokes are all enenly tensioned to the spoke and rim manufacturers recommendation, the rim is properly dished, true to within .002" and round to within .002".
Mavic open pro rim because they are well built, straight and round at the start and build into a clean looking wheel that will serve you well for years. Velocity also manufactures quality rims that build into great looking wheels.
a well built wheel should not require a re-true after the first ride, it should stay round and straight and require nothing more then minor touch uo once a season. wheel true and durability is directly related to proper and even spoke tension.
When it comes to wheels, you can always spend more money but is the money well spent.
