    If it is custom or for you then I think it is fine, but with isen we have to just work on worst case useage scenarios for everything, as we wont know who is going to use it, and how, so need to be belt and braces.

    Don't think stones would fuck it, but its the falling off/man handling/ leaning against other bikes that does for them.

    Never used the plain guage stuff but assume it would be fine. They brought out a anti dent variant last year, but have never been able to actually supply it. I'd just use Reynolds if you think yiu might smack it.

    It can do, its one of the optional extras, we made a kit to make any thru axle fork run guards. Drop us an email and fenella can run you through it.

    yeah, main triangle on goat is 853, none of the columbus stuff is hard enough for a mtb in my experieince. Dents do form character, but creases propogate cracks.

    deda or columbus down tubes, reynolds are still too conservative with road tubeset wall thickness. Deda on all seasons, and columbus on R3. the columbus spirit tube is lighter, but can dent with a reasonable whack, which isnt suitable for the all seasons as it is supposed to be an audax ready, treat like shit while sleep deprived frameset.

    All steel alloys are essentially the same stiffness, its wall thickness and diameter that makes the difference, and wall thickness is much of a muchness with above mentioned tubes. It is perfcetly possible to build a bike that is far too stiff from tubes available to us today, dependent on compnent choice. However, with the availability of good quality higher volume tyres, the definition of too stiff has moved. A 54cm frame, with 44mm dt, 31.8st and tt, 18ss and 17x30cs will be (ive tried it) unbearable on 28c tyres at 100psi, to the point that I wouldnt want to ride for more than a few hours, but will be amazing as far as power transfer is concerned. However, the same tubeset built around maybe 40c's, or even 650b x 48 tyres at low pressures, will be perfectly comfortable for a long time in the saddle, while still very stiff (once tyre squirm point has been passed). The biggest thing to effect frame design in the last ten years (in my opinion) is tyres. People like to make a lot of noise about tubes, but the reason we choose specific ones is nothing to do with shape or alloy, but but length, wall thickness, shape and how hard they are.

    Thanks @pascalo, and thanks for giving me the chance to sort it out. For numerous reasons this has been a bit of a anus horribilus for me, but despite me essentially shutting down and hiding from everyon, the forum has yet again shown me the best side of humanity, which considering we are on the internet is pretty impressive.
