These were made from stainless steel M4x8 set screws. A basic 4mm x 34.7 degree taper. Sets up for a nice 1.5mm tip.
The performance gain here is that it is now a lot easier to position my foot on the pedals with a high degree of grip with very little loading. Definitely an improvement in riding the bike.
I got a chance to compare the HT AE12 pedal to the AE05. It’s definitely a narrower and smaller pedal but I’m not interested in anything smaller than the AE05. It’s really as small as I can go. This may be good for women and children.
