I have a 2×10 setup with a 42/27 fsa comet crankset. I want to move to double and bash with 38/24 but the fsa seems to be unique in it’s design and finding chainrings/bash for it has led me down a dark alley so far.

Being skint and it running up to xmas i was thinking i could use a 9spd deore HT triple crankset i’ve got, swap the inner and middle for a 10spd 24t & 38t and bolt a cheapo bash to the outer.

Would this work?

I don’t want to go 1×10 as i have to do too many road transitions (don’t own a car) and i need a granny ring as there’s some bloomin steep hills around this way

Yep that would be spot on – the cranks aren’t specific to 9 or 10 speed. And to be honest 9 speed chainrings if you’ve got any spare would work almost as well.

Only trouble I’d see is getting a 38t – 36 is more popular and more freely available (i.e. cheaper)

thank you 🙂

i’d prefer 38t but will settle for 36t if i can’t find one
