No idea how it rides, but yes it's stainless: http://www.genesisbikes.co.uk/blog/27/0 ... in-numbers
Aluminium, carbon and titanium have their merits, but, for me, purely as an example of craftsmanship it's difficult to beat something made of lugged steel with a nice paint job.

Re: Re:
Reminds me of a lovely old Mercian Tourer i had bitd. You cant beat bike art
Saw this on your link 'There’s no doubt that Reynolds 853 rides beautifully, but there was always going to be the weight penalty hanging overhead; its’ overall strength dictating how thin you go with the wall thickness with compromising the structural integrity of the frame."
I remember the caveats with the 753 ATB race frames being one season only or a FAT 10th Ani for sub 190lb riders. Personally my fav steel rider is my 89 FAT made from Tange Prestige main triangle and Dillsburg Aircraft cromo rear stays. Its light enough and feels amazing to ride, even better than the later higher tech thinner wall TT Ox tubing models. Sure they will invent some new alloy or compound that takes it to the next level.

Re:
Yes, but 953 is even stronger, allowing it to be made even thinner and therefore lighter:
So, what makes 953 so special? Its big trump card is its strength. It’s off-the-scale strength. 953’s UTS (Ultimate Tensile Strength) of 1750-2050 MPa results in a superior strength-to-weight ratio, enabling Reynolds, in combination with oversize tube profiles, to draw very thin walled tubes (Reynolds will butt down to 0.3mm in places) and give an overall frame weight comparable to that of Titanium but nearly twice as stiff. To give you a bit of perspective Reynolds’ former flagship 853 steel alloy has a UTS of 1250-1400 MPa, 7075-T6 (heat treated) Aluminium - 510–538 Mpa and premium Grade 5 Ti-6Al-4V Titanium – 900-1150 Mpa. It’s strong. It’s crazy strong!
Good point about rider weight, a frame that feels great for a rider weighing 50 or 60Kg might feel way too flexible for a rider weighing 90 or 100Kg and vice versa.

Re: Re:
That is kind of irrelevant as Titanium galls when cutting, which jams the saw by filling the teeth. Therefore it's tough on tools and 6/4 is terrible to work with.
I spent a whole morning cutting off the thin titanium safety cladding from a helicopter gearbox many years ago. My colleagues exploited my 19 year old keenness for what turned out to be a horrible job.

If anybody needs convincing of just how tough titanium bike frame tubing is, try cutting through some with an angle grinder, then try some equivalent steel tubing. Dont forget the safety specs and fire proof suit for the Ti cutting
