Hi I have recently purchased a road bike and it came with clipless road pedals.
They look similar to the Shimano R540 SPD SL Road Pedal, but in black.
Shown here ... l-ec006321

However I now need to buy some cleats to fit it.
I am unsure as to what ones I need :? , I would like to purchase them off evans cycles but the website is unclear when describing the cleats and what pedals they fit. :?
could you please point me in the right direction as I don't want to buy the wrong ones!
many thanks. :)
