I HATE square taper, always have problems with them creaking and I've tried everything - anti-sieze, loctite, spotless and dry... but always creaky sooner or later haha.

So I'm looking for a classically styled ISIS or Octalink crankset.

I can only think of Race Face and Middleburns thus far.

I'm thinking 5-bolt only as pretty much all 4-bolt cranks I've seen are ugly and too modern-MTB looking (happy to be proved wrong!!)

Any suggestions guys? :)

Pics will help a brother too!

Cheers!

RF Turbines are the obvious choice.

Agreed 4 arms just looks wrong.

I have some newer turbines that are indistinguishable from the old square tapers fitted to another bike (once fitted)

for really modern, five arm Rotor cranks would look ok if they weren't covered in ugly graphics. http://www.rotorbike.com/products/mtb/3df_64

I picked these up the other day for a princely £40.

They're ISIS, but as slow6 says, the arms are virtually impossible to tell apart from square taper ones. The modern chainrings give it away, though.

That's weird - I never get problems with creaking (you need to do the bolts up very tight) but ISIS/Octalink eat BB bearings in my experience. They put in tiny balls in order to make space for the fatter shaft.

The first lot of RaceFace SRX bottom brackets certainly did - I think mine lasted all of about 3 weeks. However, reading the reviews of the later SRX units, they're much more reliable.

Good thing I didn't use the word vibraphone anywhere in my post.

If you can find one, an SKF BB will solve that!
