Today I replaced the pedals on a modern bike

Anyway first thing I noticed was an entry for
a hex key at the back of the pedal "screw
block" (?)

I removed the pedals just like a would with the
single speed, old steel bikes, i.e. a long
pipe, a 15mm wrench, a string to hold the crank
to the chainstay, CRC 5-56 (probably not needed
even), left pedal LT, right pedal regular, and
so very little force needed for the pedal to
come loose.

So what is the reason for the hex entry and
when do you use it?

BTW does anyone have an image with pedal parts
and terminology? I image googled but didn't
find anything to that end.


Pedal spindle (or axle - people use both terms) with allen broach:

offers faster assembly:

Fully tighten, or break free to remove, with 15mm pedal wrench.

Some pedals omit the wrench flats and have an 8mm allen broach only on
the inside.

And some pedals (~10 year old Time ATAC) omit the wrench flats and have
a /6mm/ allen socket (broach?) only on the inside. It's a bad design,
IMHO, and the 8mm socket works far better.
