Custom built wheel for BionX
First off, I'm gonna preface this post by saying I don't have any clue about building wheels...
I recently swapped my BionX PL350 from a folder (20") to a full-size bike (700c). I had to get a custom made wheel at my LBS, a guy who runs his own fairly large shop and does all the work himself.
Because of an unrelated issue with the auto-assist (referenced in a previous thread), I had to seek out a BionX dealer who could help me out. After finishing the work, they mentioned that they felt the wheel was unsafe to ride on. If I remember correctly, they said there was too much lateral movement like when cornering? They said to bring it back to my LBS and tell him to build it 2 cross instead of 3 cross. They also gave me an OEM wheel to show him.
So I tried to be sensitive about it and told him that they mentioned 2 cross for safety reasons and that I had a sample wheel for him to check out. He said that he didn't need to see it and that he built it for strength. The tension just needed to be adjusted.
I took it out on my first ride to work yesterday (20mi round trip). Maybe I'm just overly sensitive now, but it does seem to be a little wobbly when going over bumps at high speed. But I'm wondering if that's because my tire pressure was a little low (which it was). Or maybe that should be expected because of the weight of the wheel and the speed I'm traveling at (averaged around 15-18, topped out around 25)? And I don't think I can compare it to my folder because that was more of an unsteady ride, in general.

Besides the cross pattern, I noticed the OEM wheel uses a noticeably heavier gauge of spokes. Also, on the left side of the hub the spokes are all connected on the outside of the flange; on the right side they're all connected to the inside of the flange. Hope I'm saying that correctly.
Your thoughts are appreciated!
