$650.00 | | Purchased At: | Wrenchscience | | Strengths: | Perfect for riding in bikepark, DH slopes | | Weaknesses: | Weight, dont use this if you are doing more trail riding than DH/bikepark riding. | | Bike Setup: | Intense Uzzi VPP, with SRAM X0 trigers shifters front and rear. | | Bottom Line: | I have to say that this product made my day at Northstar (Tahoe). The fact that I can instantly go back and forth between drive and over-drive is truly sweet. If you ever been to Northstar at Tahoe, there is a particular singletrack (Competition-Woods)that has fast up and down switchbacks. That is where Hammerschmidt shines. In this type of tracks, weight is not an issue.
However, having said this, if you intend to use your bike more in XC trail type of tracks, even at a moderate level, this thing will kill you. My advice, dont put it on if that's what you want to do.
So my ratings are based on how it performs in bike park or DH slopes. | Value Rating: Overall Rating: |

Date Reviewed: October 11, 2009 | | Favorite Trail: | Crest-Greens | | Duration Product Used: | Less than 1 month | | Strengths: | Superfast shifting, no chain suck or drop. Stiff. Easy to setup, work on & maintain. 2lb gain overall for me. | | Weaknesses: | Outer plastic bash ring is a ankle bone killer! Too bad SRAM made the shifter action backwards from the norm. From a 32th mid ring, it's a little bit taller. 2lb gain overall. Not able to work with Grip Shift. | | Similar Products Used: | N/A | | Bike Setup: | 6.5" rear + Maverick DUC32 fork, XO gripshifters & rear derailleur, XT 760 cranks + 22th steel granny ring + XT 770 steel middle 32th & 44th alloy outer ring, XTR calipers + XT levers, LX chain + 770 XT 11-34 cassette, XTR rear hub, Mavic 823 rims. | | Bottom Line: | First generation products always get killed on reviews, this thing is killer! Yeah, 2lbs, get-over-it. The overdrive, 1.6 ratio has a slight whirring noise, once you use it enough, it goes away. A tiny bit of "windup" in overdrive; Not as bad as Rohloff/Alfine/internal hubs. Shifting action will take some time to get used to as it's super quick and backwards. | Value Rating: Overall Rating: |

$600.00 | | Purchased At: | 1 @ lbs, 1 @ hucknro | | Strengths: | Instant shifts, no alignment, downshift while stopped, very compact. | | Weaknesses: | Rediculous chain slap on FR version, a bit of noise (more so from the AM version). Solid crank arms. I fell for the "must use Sram shifter" line the first time. Have to find a shop that can face the ISCG tabs (or buy the tool). Integral chain guide will not fit on Reign-X. | | Similar Products Used: | Is there something similar? | | Bike Setup: | Giant Reign-X with AM version, Giant Glory FR with the FR version | | Bottom Line: | I love them! It took a bit to get used to the reversed shift pattern, but I like the fact that now a trigger pull is an upshift, front or rear. When I crest a hill I hit the overdrive just after the apex for a big instant ratio jump, crank downhill until the slope goes up and I start to bog, then drop out of OD to climb again.
I am NOT using the Hammerschmidt shifter. Both bikes work perfectly with Saint (M810) controls front and rear.
I used the smaller cog and a short cage shifter on my Glory frame. The chain slap is so abusive that it cuts through carbon fiber frame tape in one ride. They need a lower chain guide for this thing. | | Value Rating:Overall Rating: |

$650.00 | | Purchased At: | LBS | | Strengths: | Great idea for a crankset....seemed like it would revolutionize the front shifting on a bicycle. Worked great....until I needed a part. | | Weaknesses: | There's a cable stop assembly, that is totally replaceable. Two little allen screws...sweet! ONE PROBLEM....this part is not available in the US!!!! SRAM doesn't have them available!
So now when I hammer in the "big gear", it skips internally..nothing I can do, because I can't BUY the part! | | Bike Setup: | 2009 Kona Stinky...DEETrax wheeset, 66 ATA, Roco Rear shock | | Bottom Line: | So I pay almost $700 for a crankset, and can't buy a replaceable part?
I should be able to hammer with a Hammerschmidt.
Stick with the single chain ring! | Value Rating: Overall Rating: |

$700.00 | | Purchased At: | United cycle | | Strengths: | Integrated bash guard, Instant shifting under load, not pedaling, back pedaling, just sitting there, extra ground clearance, good looks | | Weaknesses: | Are there any? | | Similar Products Used: | There is no product out there that compares | | Bike Setup: | Reign X, Elixer CR, Mavic 823's, pro 2's, Boxxer ride, Race face bar and seat post, Kenda Nevegal's, DHX 3, blah blah blah | | Bottom Line: | I love this crank even more than I thought I would. Worth the price if you are tired of dropping a chain while shifting under load. | | Value Rating:Overall Rating: |

Date Reviewed: February 20, 2009 | | Favorite Trail: | Sidewindew in Kingdom Trails, VT | | Duration Product Used: | Less than 1 month | | Purchased At: | Landry's Bicycles | | Strengths: | Quick shifting whether coasting, backpedaling, or pedaling
Great ground clearance
All in one integrated bash guard and chain guide
| | Weaknesses: | A little pricey
Adds weight compared to a 3 ring setup
You need ISCG tabs to run it | | Similar Products Used: | Standard 3 ring / front der system | | Bike Setup: | 2008 Specialized Enduro SL Expert
Roval Traverse wheels
Truvativ Hammerschmidt | | Bottom Line: | I just put this system on my bike and have not bben able to really trail test it, but I have done a few urban assault rides and it works inredibly!!! It was pretty easy to install even with limited mechanical knowledge, but you need to make sure your bike has the required ISCG tabs to mount to. The Hammerschmidt negates the need for a front der due to the internal 2 speed shifting system. Unlike a standard 3 ring setup, the shifts are instantaneous whether the drivetrain is under load, coasting, pedaling, or even backpedaling. Ground clearence is huge due to the fact that the whole system is as big as a granny gear and with the interated bash ring, you can roll over anything. If Truvativ and bring the price down on the sytem, it could be a really big hit in the market place. | | Value Rating:Overall Rating: |
