I purchased a new bike and I want to upgraded immediately.

But am a little confused with the order of the parts.

I have a new chainset but its 9 speed. Also I don t want to change the gear shifters where is 8 speed.

Its any problem if the cassette and the rear and front derailleur its for 8 speed and the

Chainset is compatible with 9 speed?

Thanks in advance

ps do you suggest me another economical solution?

    just run it as is. one of my bikes has 9/10 hollowtech chainset and 8speed chain/block. the only difference is the chainrings are a little thinner. it wont alter anything in practice.

    it will be fine

    if you're concerned about ring rub then just fit a 9spd chain

    +2 no problems as the amount of shift is the same. The only thing you may need to change are the wheels if you have a 9 speed narrow chain.
