I had a taster today of what that might be like. Yesterday I had a few
problems with my rear indexing. This morning I found that whenever I
tried to shift to a bigger sprocket, I couldn't shift as far as I wanted
to. 3/4 mile from home I stopped to investigate and found that the
cable had snapped, so I was stuck on the smallest sprocket.
I had to decide then whether it was better to keep going or to head home
and change bikes. I decided to keep going. With a fully functioning
triple chainset I had a choice of 3 gears - 63", 95" or 118". With no
serious downhills on my commute using the 118" gear was out of the
question. Fortunately 63" is only just below the range of gear sizes
that I usually use on the flat, so it was useable. I even used the 95"
gear for about a mile.
So, not too bad (wouldn't want to repeat it regularly), but it was
bloody hard work starting off and getting up hills. I was surprised
that I managed the hill up to the office, and even more surprised that I
managed the climb out of the ring road underpass on the way home - 4mph,
a 63" gear where I usually use a gear half that size.
