That's exactly right. Back in the day when I rode with a club in the UK,
used to remove the block and replace it with a single cog and BB lockring
for winter riding, often dispensing with the rear brake, but never the
front. The law was very strict about having two "brakes". The question
should be, why did Nick March describe this as a track hub when it does not
have track threading?
