Hello

Ned some clipless/platform pedals for half commuteing and offroad, about budget 20-40 £

Thanxxx 🙂

If you mean clipless on one side, flat on the other, then the Shimano A530 pedals are nice.
Shimano call them road or touring pedals, but they are standard SPD, so you can use them off road if you want.

I recently got some Shimano M424 spds from Wiggle for the same reason. £19.49 in the sale at the moment.
I’m very happy with them. The platform isn’t as big as a proper platform pedal, and with thin soled shoes you can feel the spd part in the middle, but loads more comfortable than riding on regular spds in flat shoes.

You can also get PD-M545 for £33.45. They look similar but have an alloy cage rather than plastic.
