Which meant.... test ride time! I was pretty happy to be riding a girls bike around the park at last...
Unfortunately with the chainring on the outside of the triple cranks' spider the chainline was pretty extreme to the lower gears and consequently the chain kept jumping off.
The solution seemed obvious - move the chainring to the middle position. Unfortunately, Shimano had seen fit to include a little lip on the inside of the spider to stop you moving an outer ring to the middle position. I still can't work out why they do this... but a bit of googling and a conversation with a mate confirmed that I would be probably be best off filing the lip off.... so... another day!
