View Full Version : Wheel true question.

Just got a set of deep V's and because of my track bikes tight clearances, I need them to be pretty true. I have straightened them out pretty good, but the rear one has a massive hop in it. I don't know if a 'hop' is the industry term, but its kind of egg shaped.
Does anyone here have any tips on how to get it back into round?

do a few bunny hops on the pointy end?

Sounds like uneven tension in the spokes, where the side with the hop is a fair bit tighter than the round side. Carefully loosen them off, working around the wheel and retension. Hopefully they spring back to round when the tension is released.

Which reminds me of a joke i heard today about Velocity rims.

wheels new or old? might be flat spotted and if so is not really fixable. boo.

Brand new but factory seconds.

maybe thats the factory second bit about them. but as grant said they may just be unevenly tensioned. If you can be assed pull them apart. and see if the rim is round. and then rebuild if it is. but that is a pain in the ass.

Yeah I think I'll just trial and error til I can get them into a wheel building device. I have tried crank's method (thanks for the tip btw) but it doesn't seem to be doing anything.

i say ride it for a while, let the spokes settle (so to speak..) , and then have a go at it.....

take it back to tom and have him true it :P

supposedly the the factory seconds are paint issues not actual defects with the wheels...
