I build a set of farsport 20 mm tubular rims and soul prodigy hubs. the front wheel was no problem at all but i had trouble with the stiffnes of the rear wheel.
I built this wheel with 288mm dt comp. (2x ds) and 288 mm dt rev. (radial nds). after the first ride i noticed a crack in the rim at the valve hole. I think this was because the rear was flexi as hell
the rim is too light for rear built.
tension was 210 kg (ds) and 70 kg (nds)
I am 85 kg....
What should I do? build the rear with 38mm rim, or order a heavyer (more durable) 20 mm rim??
Pino, i found these sets of articles to be quite useful and well written when considering lacing patterns. The linked other chapters are also quite interesting.http://spokeanwheel.110mb.com/lacingsr.htm
Your aim should be to even out those spoke tensions to bring down the DS tension and up the NDS
-less chance of a spoke pulling through on the DS when the wheel is loaded
-less chance of the spokes completely unloading on the NDS when they're at the bottom of the wheel's cycle (which leads to a. increased spoke fatigue and b. spokes that lose tension easily (unless the thread is threadlocked with linseed or akin) and therefore an unstable wheel)
All the best, I
thanks for the link.
I relace the wheel with radial (ds) and cross 2x (nds) and see if it makes any difference.
