Changing the entire chain gear mechanism I have a Lapierre shaper 100. 

I am looking to change my entire chain mechanism as some of these parts need to be changed. I have selected my components, and I am hoping you can tell me if these parts will be compatible.


Shimano Claris FC-2403 crankset
Shimano CS-HG51 8-speed cassette
Shimano Claris RD-2400 GS rear derailleur
Shimano CN-HG71 chain
Shimano Claris FD-2403 B front derailleur


I would really appreciate your thoughts
Addressing only the technical compatibility, if you currently have a Shimano 8x3 setup, and you wish to upgrade to another Shimano 8x3 setup, then any Shimano 8-speed road parts should be fine.

So that includes Claris, Sora, Tiagra etc. as long as it's 8-speed kit. Same goes for the chain.

I mention Sora and Tiagra just in case you're able to source these "old" parts at a decent price, off eBay or something.
