I'm not a professional wheelbuilder. I've only accomplished conventional 3cross wheelsets. I've built, trued, and repaired my own conventional wheels for years.
But I've encountered something which I may need some guidance.
I recently bought a set of the new Shimano RH550 pre-built wheels. On one of my first outings, I had an encounter with a four legged beast which is chronicled in another section of this forum. In my attempt to avoid the beast, I snagged my tire valve on some roadside debris which consequently tweeked my front wheel.
Now I need to straighten it. The wobble is slight and only side-to-side. The rim is still circular.
Should have been a simple tuning project as I've done this many times with conventional wheels. One new challenge which shouldn't be a problem is that the nipples are at the hub rather than at the rim. BUT these wheels only have 16 radially laced bladed spokes on the front wheel. The spacings inbetween spokes are wide.
Correcting small lateral wobbles seems to be impossible if the rim malformation is inbetween spokes.
Is there a method for straightening a wheel with so few spokes? Any special considerations for Shimano wheels with Nipples at the hub? I already discovered that it doesn't use conventional spoke wrenches and uses an unconventional oversized nipple. Again easily overcome using small metric wrench but difficult to twist when mounted in my Park truing stand.
