Shimano SH51 SPD Cleat Set - Single Release (aka pedal clips)
Cleats feeling crap? Grab a new pair! Shimano SH51 cleats are single release, none of that terrifying multi-release stuff. Though we don't personally run cleats on our mtbs, we hear that Shimano make the best cleats - so that's what we stock.
You've got the choice of cleats with or without a backplate. If you've already got a backplate, that is in okay condition, then save yourself some cash :)
These are compatible with all modern shimano mtb shoes and pedals. The only exception we know of is the old pedal model PD-M858
