Hi, Andy.
Thanks for the last post. one other question as I ponder the merits of your bikes. I need a frame which will withstand a semi-permanent coating of mud, and put up with inevitable stone chips without rust affecting it. I commute to work every day off road whatever the weather, and I find time to clean only the running gear.
My experience is mostly with alloy, which doesn't really care about this sort of neglect. I have memories of 1970's steel cars falling apart. So just how good is the 853 tubing for rust? Would I expect to be needing to lay the bike up, and re-paint the frame in 5 years down the line to prevent damage, - or is this steel good enough such that the paint is largely cosmetic?
