These are due to arrive in about four long, long weeks on my Orange Sub5. However, I've not seen any reviews and even a search on Google brings up next to nothing.

Does anyone know how they compare to other cranks? Are they cheapo things that I should consider upgrading now? Or are they the mutts nuts?

I'm about 16 stone when reasonably fit, so a good crankset would be a sensible investment.

I'm not sure on these, they lool a bit like a cross between a Prodidgy and a Turbine. Probably a OEM item as Prodidy's once were.
In my experience of Race Face stuff it's always top notch gear.

should read : look

my bf has oem race face cranks/rings on his new marin; the granny ring collapsed under no pressure at all when shifting.
Dunno if these are the same as enduros.

If they're new that must be a dodgy set.
I'd be more worried if I heard they were collapsing after two months.

I think they're basically a Turbine LP minus some of the extra machining and in a four arm format. They look "real" Raceface rather than Prodigy.

All of the RaceFace stuff on my bike is first class and I've had no problems with them. Just be in the thought that they have a warranty...
