Shimano Deore FC-M532 Chainset - replaceable cogs?

Macster1

Hi all,

I have a Rockhopper Pro Disc 2009 [new in May] and was loading it on the car roof the other day when I noticed the outer cog teeth were getting bent

Inner two cogs are steel, the outer is alloy. I have had some suspect gear changes where I missed changing in time so I guess this has done it as I normally just ride around normally - woods and road riding.

Does anyone know: -

1. Can I replace the outer cog only or do I have to buy the whole chainset?
2. If I can, anyone know where as I can only find the whole chainset for sale?
3. What is the most likely reason for the teeth bending and will it shag my chain if I don't fix it?
4. Any other advice welcome!

Thanks in advance

you can replace any of the rings.

BUT the teeth are shaped to aid gear changing.

Thanks, I'll look into it.

On another note, can I change the amount of teeth on a cog to make me go faster? Sometimes when I'm road cycling I'm in top gear - largest front/smallest back, but still feel like I could go faster, that is to say I feel like I'm having to put more work in than I should. Don't know if that makes sense?

Thanks
