Well I think it's time for me to start upgrading my trail bike. I currently have Tapered Race Face Turbine cranks with MRP guide. Ya I know, why an MRP on a trail bike? Just didn't want to sink any $$ into it, reason why now I want to upgrade and add a front derailleur.

My options:
1) simply buy 3 rings for the Turbine cranks
2) upgrade to a new ISIS crankset.

what do you suggest?

There is nothing wrong with square taper stuff for xc use. These days incredibly nice square taper bb's and 110 or 94 bcd chainrings sell incredibly cheaply.

I'm one of those suckers who bought into the hype... but those are sweet cranks, no reason to ditch them.

Yep, as long as you aren't putting your cranks through too much abuse, square taper should be fine.

Not sure if you saw this thread, but general consensus is square taper on good cranks is fine for XC/trail use, especially since you've already got them. Might be different if you were just building the bike. Since you've already got the Turbines, I say keep em and get a couple two chree rings.

I'll just keep my Taper Cranks and get a good ol Shimano un-91 BB or maybe even Phil Wood.

The amount you'll spend on chainrings you can pick up a set of LX cranks and BB or some XC Race Face ISIS cranks for the same price.

And his cranks are way, way nicer than either lx's or Prodigy's.

Um, maybe I'm missing something... but chain rings are pretty dang cheap at my LBS. ~$60 for the 3 rings... lasted me 3 years.
