I’ve had a quick look online, but can’t find anyone selling them – anyone know where I may get some?

Evans do a Sidi stud – http://www.evanscycles.com/products/sidi/mountain-bike-studs-ec033623 and
CRC do a DMT stud – http://www.wiggle.co.uk/dmt-toe-studs-bicomp/

I guess either of these may fit, but I’d prefer the originals if I can get them

You can get a pack of 20 aluminium rugby boot studs from Sports Direct for £1.99….

Cheers John – I assume they are a generic thread then?
With the amount of pushing I do, a bulk buy might be a good idea 😳

Most sports shoe studs have an M6 thread, be they football boots, rugby boots, MTB shoes, some golf shoes (although I wouldn’t recommend golf spikes!!), whatever. All much of a muchness.

Football/rugby studs are usually sold with a key to insert/remove them too, although if they aren’t, Sports Direct sell keys separately.

BTW rugby studs tend to be longer than football studs, and most football studs are plastic these days.

Yeah they’ll all fit. Football better than rugby IMO, you don’t want something quite as protrudey (can’t believe Firefox thinks that’s a word!) as a rugby one.
