Hi All,

Never worked on a bike technically before but very technically minded having rebuilt motorcycles and cars in spare time so i'm sure ill pick it up quick enough, just need a little advice on getting correct parts for replacing cassette, chain and crankset for my new pre-loved specialised vita (pretty sure its this one - https://www.specialized.com/gb/en/vita- ... 573-106273).

According to the website it has a:

CASSETTE - Shimano, 8-speed, 11-32t

CRANKSET - Shimano FC-M131, 48/36/26T, w/ chainguard.

Does this mean that I can put any 48/36/26T crankset on the bike or does it have to be the shimano FC-M131? Same question applies to the cassette - can it just be an 8-speed, 11-32t or only the shimano branded product?

Equally speaking, does it have to be a 48/36/26T crankset or can I, for example, use a 48/38/28T shimano crankset?

I guess what i'm asking is, what specs are important when replacing with new cassettes and cranksets or can I use any three cog parts?

I've watched a few youtube videos and the replacement I can easily handle. I just need to know the correct parts.

TIA
