Strengths: Strenght enough to withstand my 118kgs when those nutns transfered to crankset. Never had problem with it. Used mainly on road, but mountain's trails, also. Arms are also strength enough not to bending while hard pushing.
Weaknesses: Sometimes, teeth gets bend. I used clamp to unbend.
Very strength crankset for moderate and sort of dirt riding. I used it for accelerating very fast on road. After 25000km it just gets old and those space beetween teeth became bigger and chain get stuck beetween very often, so I need to replace it with the same :)
This one I had is 2007 model, and the new one is 2010 model. This new one looks more weaker then previous one. Gears are way to thin and bends easier. I hope it will last at least half of the time the first one.

Strengths: Reasonably light, spins well, shifts well, no noticeable flex, all black, quiet
Weaknesses: Middle ring became unusable after 650mi, bent teeth, missing teeth
No complaints until the middle ring stripped. Replacement is inexpensive and middle can be replaced without removing crank. But still, new rings after 650mi in 9mo. The RF Ride XC on my son's bike is still going strong (did have to relube BB on his though). I am new to sport and there may be some user error, i.e. too much load shifting.

I've used a lot of different cranks, the bike came with RaceFace Ride XC but they flexed the chain against the mech everytime I stood up. These Firex cranks are the best cranks I have ever owned - not too heavy, bombproof so far (hard XC & AM with a full 230lb leaning - and landing - on them). Even the bottom bracket has put up with 18 months of hard muddy UK riding - 3 times more than anything I had from Shimano. Looked at 'upgrading' but tbh there's nothing better for what I need from a crank, regardless of cost.
This came on the bike, this was my first experience w/ Truvativ. Been on Shimano and RF for 13 yrs. I was very impressed with the quality. Shifts up and down flawless and I ride this bike through rock gardens at full speed and have hit rocks and these cranks and rings have been amazing!! BB has been flawless and smooth as butter!! I have to say that I have now been riding all SRAM since I got this bike over a year ago, and I have a new Sortie Black as well and love the Noir cranks too. I am in love with SRAM, sorry Shimano.
I have a set of Truvativ Firex Cranks with a GXP BB. The problem im having is when i slide on the drive side, it dosent go all the way on. There is about a 1/4 inch left.
So when i install my MRP G2 on the iscg tabs i have to use one washer to move it out.

The bolt on my gxp cranksets seems to want to back out and drop my crank off. I know they aren't the most expensive cranksets but I expected better.
The design has a bolt and then a self extractor nut that goes in after that hopefully would push down on the bolt to keep it tight. The idea is a go ... Read More »
This is suppose to be the stock crank/BB on my 09 Devinci Hectik. I went to remove it, first removed the non-drive side and went to pull the drive side off and it wouldn't completely come out, I tapped it with a hammer and block of wood, nothing. Frustrated I removed both bearing cups and everything ... Read More »
Need a hand here. I've searched the web and this forum and can't find anything that clearly explains how to remove the cranks that I have. I have Truvativ Firex 3.3's on my Cdale. I'm trying to remove the cranks so that I can take the 22T ring off. I understand that these are a GXP ... Read More »
