Tour de Fer - 10 or 20?

[astrocan]

My daughers Croix de Fer was stolen and in the process of replacing it she has set her heart on a Tour de Fer. The TdF10 is available now but the TdF20 won't be in until end of June and I know how reliable these predictions are (not). I am looking at the possibility of up-speccing a 10 but the frames are made from different tubes. The 10 uses Genesis own Mjolnir double butted seamless chromoly, the 20 Reynolds heat treated 725 chromoly. Is there a massive difference in the performance of these materials? I am working on the assumption that both share the same geometry.
Any advice and or experience greatly appreciated.

Little difference between materials. The mechanical characteristics, tube profile, butting, diameter etc may differ though, and the 725 may be thinner wall and thus a smidge lighter.

Mjolnir is 4130. More or less a Reynolds 520/525 equivalent. All other things being equal the 725, being heat treated, should be stronger for the same weight, meaning it can be built into a lighter frame for the same strength as the ;lower grade steel. That said; Genesis make good bikes from each and every ime.

Freeborn has both the 2016 10 and 20 options. 10 is a much nicer colour

I'd like the extra kudos of the Reynolds badge but Vickster could be right in saying it might just be down the colour in actuality.

You mean it ain't black.

Nor is the 20. The blue isn't bad, the copper much prettier tho

Agreed. I suspect in reality there's little in it beyond a few extra bragging points down the Steroid and Lycra.
