When you ride, they feel quite strong and secure, and the change between rings are good. They came with my bike, but i prefer shimano, or at least with non integrated bb | Value Rating: Overall Rating: |

Date Reviewed: December 8, 2007 | | Duration Product Used: | 6 months | | Purchased At: | Sportz Outdoor | | Strengths: | When it was working it seemed to work well - clean shifts, stiff BB. Plenty of times I hit rocks thinking I would have lost a tooth but it was over all bulletproof... | | Weaknesses: | The crank arm fell off on the non-drive side after only about eight rides. As it was my first season on a MTB I couldn't have been riding it very hard. It had been an unusually wet Spring in New Mexico so I did do several dozen stream crossings but that shouldn't have caused a problem like this, right?
It cleaned up and re-attached OK for about another couple dozen rides then became loose again and would no longer last for more than a few miles before needing to be tightened until eventually I didn't trust it at all. | | Bike Setup: | 07 Fisher Paragon - crankset came on it OE | | Bottom Line: | I only got perhaps 400 miles out of it before giving up and having the entire crankset replaced while still under warranty. I'm hoping it was a fluke and that the replacement lasts much longer...
With the exception of the arm falling off it worked great (seriously) and I was very happy with it's performance. If the arm hadn't have fallen off I would be giving this a high overall rating and a "fair" value rating... | Value Rating: Overall Rating: |

Date Reviewed: June 25, 2007 | | Duration Product Used: | 6 months | | Strengths: | It worked fine until it fell apart with less than 100 miles of riding. Makes a Great Paper weight though. | | Weaknesses: | I bought it brand new. Came stock with the bike.
It fell apart. Only took it out to ride for about the 4th time ever. The crank arm on the non-sprocket side fell off. It was never even ridden that hard. Never abused. The damn thing just fell off. Tried reattaching it back on the trail. A few miles later, the The crank arm on the non-sprocket side fell off again. This time all the threads were ripped off with it. I could no longer reattach the arm because what was left of the threads wouldn't hold. It was so bad that I could tug the arm off with my bare hands. The crank was completely ruined on my 4th ride on the bike. | | Similar Products Used: | Shimano XT. Shimano XTR | | Bike Setup: | 2006 Gary Fisher Fat Possm XT | | Bottom Line: | If you read other posts from other riders, I'm not the only person who has had this problem with Bontrager cranks. Apparently this is not one isolated incident.
This crank is total Crap. Save your money and go with a shimano. Unless you are some sort of massochist, don't even bother purchasing any bike that comes stock with this product.
I hope the executives at Bontrager read these reviews and hang their heads in shame for producing such an inferior product with an inferior design. It's not only an embarrassment, but a legal liability. They have lost a customer for life. | | Value Rating:Overall Rating: |

Date Reviewed: June 22, 2007 | | Favoriate Trail: | Cannonburg State Game Area | | Duration Product Used: | 1 Year | | Strengths: | I guess it looked nice new. | | Weaknesses: | It fell apart. | | Bike Setup: | Gary Fischer Paragon, new out of the box. | | Bottom Line: | This bike is about a year and a half old, but I only ride is summer (Michigan). So, a few times a week I hit the trail for a couple of hours. The crank arm on the non-sprocket side fell off. Upon inspection I found that the threads holding it on were right handed making this inevitable with enough time and backlash from use. So, I pursued the torque spec, put it back on with thread locking compound, and it fell off this time taking the threads with it.
Bottom line, I have a lightly used $2000 bike that is falling apart because this is a lousy crank design. Avoid it if you can. | | Value Rating:Overall Rating: |

Date Reviewed: June 2, 2007 | | Duration Product Used: | 1 Year | | Strengths: | Good Shifting, stiff | | Weaknesses: | Heavy, finish wears off, dubious alignment of chainrings, shockingly weak Truvativ GXP BB. | | Similar Products Used: | FSA Afterburner, Shimano M440 | | Bike Setup: | Stock 2006 Trek Fuel EX8 | | Bottom Line: | Came fitted as stock on my Fuel EX8. First impressions were great - excellent shifting, good power transfer and no noticeable flex. After 50 miles the drive-side BB failed but was grudgingly replaced under warranty. After another 100 miles the drive side BB failed again. Given the 4 week turnaround last time I won't be claiming it under warranty again.
On closer inspection, it looks like the cranks could be to blame as the middle chainring isn't true - it bends toward the frame by about 2 - 3mm for a run of about 4 teeth close to the crankarm.
If I've managed to do this while riding (and I can't imagine how I could!) then the chainrings are horrifically soft. If it came like it from the factory then it's pretty poor quality control. Either way, I'm swapping it for a Shimano. | | Value Rating:Overall Rating: |

Date Reviewed: May 24, 2007 | | Duration Product Used: | 6 months | | Purchased At: | Came on bike | | Strengths: | GXP, stiff, shifts well | | Weaknesses: | I would prefer all black chainrings, but whatever. | | Similar Products Used: | Stylo GXP | | Bike Setup: | Trek Remedy 6 | | Bottom Line: | Pretty good crank. The external BB is nice and it has been stiff so far. About average weight for a crankset. I really like this crankset because so far it has been a "set it and forget it" type of relationship. | Value Rating: Overall Rating: |
