Cannondale SuperSix Evo kids bike

Curiously there are CAAD10s and SuperSix Evos with shorter reach and higher stack measurements - a '51' can be had with a 53.4 reach and a 37cm stack which in terms of reach isn't far off your 48. +2mm reach with a further 21mm stack I think, looking at the geo charts. Problem is, they are branded 'women's' and are probably difficult to get in the UK.

If this is true, might one solution be to accept this frame as ugly, ride it through the summer (and winter) and keep it as a crash-able race frame, whilst trying to get one of the CAAD 10s, which will be easier to re-paint as its alu, and might fit a bit better, as a long term bike?
