My wife and I are planning a long distance tour this spring using our Cannondale RT1000. There are changes that need to be made to the bike to get it ready for the trip, the biggest being a set of stronger wheels. I've been looking at Phil Wood hubs matched with Velocity Dyad rims and recently came across a set at a great price. The only problem is the rear hub has a 160 spacing and our Cannondale is 145. Is it possible to change the spacing on the 160 Phil Wood hubs to 145? Any comments, suggestions or how to help would be greatly appreciated. Thanks in advance.
