You might be able to salvage them if they are just loose and the cups / cones have not been ground away. If they sound 'gritty' and are loose that is usually not a good sign. Your best bet is just to have a go , if you have the tools / time and possibly want a learning experience. Personally I have moved to Shimano PD-M520 SPD mountain bike pedals but of course these need shoes with cleats and at least for the UK you need to buy reflectors for them as an extra to stay legal at night. Also SPD type pedals don't have much scope for sideways adjustment so it is sometimes better to have the cheap ' flat pedals' as you can put your feet where you want. I know this is extra information but if you do decide you want replacement pedals it gives you a tiny bit of information what the options are.

@@dawn_rider Thank you for your response. Most helpful.

@@ianhill4585 I forgot to add that for my pedals you need a special axle removal tool which In my case is the TL-PD40 so you have to keep such things in mind for any new pedals you buy. Just for comparison to this video , this is what is involved for my pedals kzfaq.info/get/bejne/n8yJncd5l8eslGw.html .

@@dawn_rider Cheers again.
