Just looking for some suggestions for new lighter cranks for aggressive trail use. Currently running NX and have upgraded most everything else. Not looking to break the bank so I guess carbon is out. TIA.

The GX Eagle DUB crank is 620g including a 32t chainring. With the BB it's a bit over 700g.
Not sure if that is light enough for you.

If it helps you here is a weigh spreadsheet.

It's german, but maybe it helps.

Cheers!

Recently ran into this issue, went with the gx crank with dub for $220 with shop installation. Better material over the nx, but if that isn't an issue get the nx for a tad bit cheaper

These may be worth looking at. Descendant GXP 170mm Might be cheaper in their Ebay store.

They are new with no packaging. Mine were perfect, never installed and not a scratch.

I swapped in a steel 30t chainring, then weighed them at 710g. Not amazing but the price is right!

Easy, Shimano SLX, but you'd need a dif bb.

I got a set of Trailcraft DirectMount cranks. https://www.trailcraftcycles.com/product/trailcraft-direct-mount-cranks/

600g with ring for $160, and it comes in 165, 152, and 140mm lengths. I went with 152 and kept it on my bike. Feel no urge to go back to anything longer than 165--actually feels like the circles I spin on 175 are super exaggerated in comparison.

Cannondale SiSL.

I have four sets. Never paid more than $200.

You've recommended them before, and I keep an eye out... but they're often well past $400, used.

There is a set of 170mm new take-offs for $250 on eBay right now. With a chainring you could sell for $100+...

Another vote for the RF Turbine. I have 2 sets. Strong and stiff AF. Light. Relatively inexpensive. Part of mountain biking history. Solid trail karma. Looks awesome.

Just picked up a set of SI Hollowgram arms for $145... off of a Super Six and installed on my Fat Caad

+1 Shimano SLX or XT cranks. Not sure what they weigh but probably the best value crankset available. I have them on most of my bikes.

I know. I'm thinking about buying them just to have around "just in case...".

Then I remember I have four sets and one set is hanging on the wall.

Not super knowledgeable on compatibility of cranksets. I currently have NX Eagle crankset on a boost bike which has the DUB spindle.
Would something like these xx1 be compatible without a bb swap with a huge hassle and do I also need to find something with a 148 Q factor? Thanks

there is the Hollowgram si and the sisl. the latter is clamshell/machined iirc a wee bit lighter and expensive. the former is hollow forged and a wee it heavier and relatively cheap. there is also a considerably cheaper non hollow crank can't remember the proper nomenclature. the si is a great option! wolf tooth and absolute black and one up do rings in various configurations for it. I use it on several bikes and on others the raceme next sl. the difference is about 20-30g iirc.

How do the SiSL cranks hold up when you're, say, riding along at 15mph and you smash your pedal into a large rock and are then catapulted into a series of trees?

With 30mm axle and tiny bearings those Turbines aren't the most reliable ones, IMHO. Also, I had on mine the crank bolts coming loose causing some nasty creak.

I'd vote for Shimano XT or maybe SLX. The HT2 has 24mm axle with proper size bearings and seals, also the tightening mechanism is bombproof, those are also fairly inexpensive and easily available on many places...

Since we don't know what BB is being used the bearing size is not the question. The Raceface BB's suck, I think we all know that by now. There are good options from Wheels Manufacturing, Hope, RWC, etc. that won't die an early death like RF.

Abec 5 angular contact bearings have proven quite durable.
