MTB upgrade - crankset

I am working on upgrading my old steel mtb. I've upgraded old brakes for Avid Single Digit 3 V-brakes and Tektro levers.

I am now looking into upgrading the drivetrain as the next step. Not sure I am willing to go all the way to XT component - but want the 27-gears anyhow.

So, do you have any suggestions for a crankset? Should I aim for a road or mtb crankset? The touring I am doing combines road and off-road (gravel). And, what should be the preferable arm length? The current arm length is 175mm - which might be too long?

Thanks for the advise.

Deore crankset at JensonUSA

Jenson currently has Shimano Deore Hollowtech II crankset for $40! I doubt you'll find a better bang for the buck.

I would go for a 22,32,44t crank set and if your bike came with 175mm then I would go with a 175mm.And the rear cassette I would get a 11-34 but you may have to change out your derailleurs on back.that's if you have a 9 speed.That's my 2 cents on this.Good luck to you.

I'll add 2 more cents to the pot. You may wish for more gear inches on the high end with a strong tailwind and when pedaling downhill, but aren't likely to have to walk the bike up steep grades. (There seem to be more steep grades than tailwinds, and downhill is for coasting.)
