I'm new to folding bikes, but I've been riding 'regular' bikes for years. I like to strip bikes down and put them back together again, partly for fun and partly so that if anything goes wrong on the road, I have some idea what I'm dealing with. However, I'm sure folding bikes are a rather different animal. Before I start taking the handlebar stem apart, is there anything I should be particularly careful about? And are there any nasty surprises waiting for me?
Thanks in advance.
