How well do they(Brompton pedal) hold up with such a small bearing surface?
the bearing itself is quite large, ID greater than 9/16" .. because the core piece shoulders against the crank arm.
There are RH& LH thread core pieces, so a pair of them can be fitted..
the Left pedal is the standard one .. the core plug for the Light er bike is Titanium,
but I dont think a Ti RH one exists
both do in steel. 24mm hex , or the newer Allen Bolt version...
FWIW: update, noted a couple hairline stress cracks in the aluminum.. bearing carrier
at 6:00 & 12:00 ..
so will chat up the service dept & see if this was in the consideration of newest version
Yes I'm aware that there are the Steel R/H cores . Noted via SJS..
I considered it to equalize the pedal weight..
