Hi
are these chainrings compatible with a 2009 RaceFace Evolve XC chainset?

Should be if the BCD and pattern are the same.

Probably cheaper options out there though.

thanks buddy for the reply

does a 104 sound like this BCD number? If so they share the same BCD

What cheaper alternatives do u suggest to the £15 deore? I was looking at superstarcomponets but they sold out :S

thanks again!

you many need to take a file to the shoulders. to get a fit.

Yep, that sounds correct!

Sometimes it is cheaper to buy a whole chainset and harvest the rings! ie:

They are all steel though, but will last ages, and you get a spare outer too. Plus could ebay the crank arms. I use this set on my Mongoose.

re. the filing down thing - is that cause of the Shimano Rings have a rounded area around the bolt section, whearase the Raceface are flat?

Is it possible to have shifting problems if the rings are not failed to perfection?

Thanks again

nope it is just the way no one uses exactly the same standard standard. not even the same maker through the range or over the years.
