Superfast213:
Those Bontrager wheels sound like the old version Racelites (RL) or RaceXLites (RXL) with 16 paired spoke rims. The lower end model used a Formula sourced hubset, while the higher end used a DT-Swiss sourced hubset. But these had a reputation of losing trueness and cracked rims. They use a 'J-bend' spoke, but will fit a conventional 14GA spoke in emergencies. Hmmm.
Bontrager/Trek soon dumped the paired style for a conventionally spaced rim and hub. So, YMMV. If you're a heavy guy, stay away.
Oh, you can wedge a 130mm rear hub onto the Cannondale. You can't cold-set Al, but it's only 2mm per side.
