this might be a really dumb question, i ride street, i have a 20" trials with an alex rim, the spokes on it are pritty loose, they are kinda snug but i can easily move them when i squeeze... are spokes supposed to be tight??? and should i just take it to the LBS and get it tuned up?? do they have to do anything different than a normal bike since it is a unicycle??
You want your spokes to be as tight as the spokes and the rim will allow; the strength of the wheel comes from spoke tension, so the looser they are, the weaker the wheel is.
That's completely inaccurate. Creaking is definitely a sign of a wheel with insufficient tension, but many wheels with insufficient tension do not creak, and are still more prone to failure.
