I’ve got two sets of MKS EZY pedal inserts for sale, completely unused but not in original packaging.
No pedals for these as I completely destroyed them during disassembly to look at the axles.
I’ve also got two sets of Wellgo QRD inserts (not the round ones), and one set of pedals to go with them. These inserts cannot be used together in two hole cranks (could be in three hole ones though), but you can get another type which allow them to fit together.
See these threads for more info:
All of this is in the UK and I’d rather not ship internationally.
The EZY inserts were quite expensive to buy, but make me an offer if you’re interested in any of the above and I’m sure we can work something out.
