Hey, The Reason that Saffa G started this discussion, is because I have just started the conceptual design stages for 2 new 2010 bikes, one an XC race hardtail, and the other an XC/marathon full sus. I am not concerned about components at this stage, just the frame design, so far things like bottle mounts and cable routings have interested me most. I am wanting more spcific feedback so that I can create a better bike for you. as for materials I am considering Aluminium (yes I am from UK, that is how we spell it) titanium, magnesium, scandium and carbon, or combinatiosof the afore mentioned. Suggestions you say now may actually become reality. Thanks, Keith
