i'm particularly interested about component interchangeability.
for example, can we use the freeride hubs on our tandems? i have seen some of the freeride hubs in 150mm spacing vs 145mm of common tandem use. if it's just a matter of shaving off a few mm of the spacers or removing some washers, will the hub itself be acceptable for tandem use? also, how different would the freehubs be?
