Hi guys

Got a good offer on the RF Nxt carbon crank, like this one with the "old" chainrings:

Theres a new 2010 version with turbine rings out these days, has this one the same crankarms as the old just with diffrent rings? - Some say they last better than the old version who cracked?

I'm planing to set it up for 2x9 with a 42/27-28 combo.

Something simmilar to this

Only thing holding me back is that I can't find any info regarding q factor, and other people saying that the break very easily?

Don't want the QF to be extremly wide + I want a crankset that can stand racing it

Any final thoughts, would you recomand it?

best regards

Sorry for bad spelling

I had a set of cranks from the 1st batch that I bought form Chain Reaction Cycles, and like many others, the chainring tabs broke. They were replaced under warranty and I tok the opportunity to upgrade to the Ti spindle version. So far so good. If it were me, I wouldn't waste my money on the Ti spindle version. It was exactly 11g lighter than my original set with Chromo spindle. I am running them 40/27, and now changing to 40/26. The 40 is on the inside of the 104 BCD tabs and the 27 (26) is mounted in the granny position. I had to space the 40 even closer to the 27 so the chain would not drop in between when shifting down.

Don't know what the Q factor is though.

I too had one of the first production run Next cranks and they had the spider's chainring bolts break out on two arms. I have a warranty replacement set now and they have been good so far. The XTR BB is lighter than the RF BB by about 25gms.

The Q factor is 170mm with the mandatory pedal washer, it could be 168mm if you left the washers out but that is not recommended.

Rings from Mathias or someone else?

Anyone know a cheap source for the Next ?
I've found 445GBP. Somewhere cheaper ?

@Blowncivic,
could you tell us the weight of the both crankarms (incl spindle ;-) only ?

Tanks.

My 175mm Next cranks were 454g w/o BB.

First generation carbon NEXT crankarms with cromo spindle..​

Pictured above (without BB) is my NEXT cankarms with an ExtraLite GARA 42x28t ring set..​

Final weight of 624/625 grams for the complete crankset..........

Nice!
Did you use any spacers for mounting the 42/28 combo?
Are you satisfied with the 2x9 setup?
How do I tell if I buy a "first batch"(craking) set or not?

 

[rockyuphill]

Unless you're buying used Next cranks there's almost no chance you'd have a set of early cranks, it's been about 15 months since that small first production run happened and they sold out pretty fast.

If you're buying used cranks, I'd make sure the rings get taken off to inspect the spider bolt holes.

I've been wondering if my crankarms are 1st or 2nd generation..
I found a picture of the 1st generation, pictured below.​

Above and below circled in red is the difference that I found on the spyders..
Below is what mine look like..
Might be that mine are second generation and that's why there holding up after a couple hits.​

"Did you use any spacers for mounting the 42/28 combo? "
No spacers needed for the GARA ringset..You can use a single ring fastener to install.
I didn't have any single fasteners so I put a spacer on the outside of the spider and used
a fastener for a double ring set-up.

"Are you satisfied with the 2x9 setup?"
Love it, the shift is flawless with my SRAM XX front dérailleur and grippers..

This is what the spider looks like when the bolt holes fracture. I hope the new ones will stand up.

Ok ive decided to give the crank a go. Let's hope For the best

Does anyone know why the RF next and other carbon cranks have the pedal washers that you have to use? I'm not quite getting how moving the pedal outboard would help.
