It seems that I’ve got water into my gear cables – and when the temperature dropped to -5C then froze solid, leaving me stuck in one gear. There seemed little point in having snow & ice tyres but then only having one gear when it became cold enough to take advantage of them. So, a trip to my excellent local bike mechanic – ATR Cycles – led to us working together to replace cables and housing. Indeed they were full of water. So now I have a new set, and the old housings in the airing-cupboard to dry out for next time. I’ve seen some rather neat oil nipple accessories you can fit – but that would mean removing the cable and then re-fitting again – so this seems a job to leave until they freeze again, or at least until the summer when my workshop is well above zero celcius!
