Wider rear FD axel

[leefitz]

Cheers, I have been playing with pressures, up to 50psi. It\'s a standard 1994 so there\'s no grate abundance of power.

Thanks lads, I to believe that it is more difficult to widen the rack than just lengthening arms. Excluding the ability to go with deeper dish wheels and higher pressures inside the tyres, I don\'t think increasing he spacers is acceptable either?  

Is there such a thing as a safe maximum size your spacers could be? surly 50mm is about the limit or could you push wider?
