They (John Kovachi and the Drummonds)don’t recommend titanium spokes for the sun doublewide rim, saying that the stiffness of that rim and the stiffness of the titanium spokes will cause the spokes to pull through or deform the eyelets. Something needs to be able to flex a bit under load. For other rims they’re OK I guess.
Some of the Kovachi wheel builds are quite expensive. Over $100 for a wheel build is a bit much. I don’t know why the cost of some of the wheel builds have gone up so much. They didn’t used to be that expensive.
At that markup it makes more sense to just buy the parts and have the wheel built locally. I’ve been getting my wheels built by a local wheel builder. The hard part is finding a shop that can build a good muni wheel. Not all shops are expert wheel builders. The trick is finding a good wheel builder. I’ve found a local shop that does an absolutely fantastic job building wheels. He’s a freerider and builds wheels to take freeriding abuse. I’ve had zero problems with any of the wheels he’s built. And it’s $30 labor for a wheel. Saves $70 over the Kovachi build and I’m getting what I feel is a better wheel.
