140mm Rear Axle spacing? What are my options?

[wongmic75]

I am trying to build up my tandem and noticed the rear hub spacing is 140mm... What are my options?

I was tempted to turn it into single speed with ENO hub, but they don't seem to make that size? Any suggestions?

IF I can't turn it into a single speed, maybe just a regular 9 speed rear hub in 140mm... Would a 145mm tandem rear wheel be able to squeeze in there without damaging the frame? It is a Ti frame...

Any thoughts greatly appreciated!

Shimano HF08 / XT Tandem Hub
White Industries "Daisy" Tandem Hub (Racer X, Jockey, etc...)
DT / Swiss 540 Tandem Hub
Phil Wood FSC Tandem Hub
Chris King Tandem Hub

Best bet is to check with the tandem specialty dealers like TandemsEast.com, PrecisionTandem.com, or authorized dealers for the aforementioned hubs. They are listed in general order of price, with Shimano being the best value models and Phil Wood / Chris King at the boutique level.
