I have a "zenith" double fixed large flange hub which i'm pretty sure is a rebranded iro/formula etc. i've spaced mine to 126mm fine, looks like theres a bit more room there too. i've seen stuff on harris cyclery (sheldons place) that suggests as standard they come with a shorter axle though, they special-order ones with the longer axle although some places do swap them out themselves. i think.
