Origin 8 2X9 Cranks: Final Review

August 27, 2009

I have been putting the Origin 8 2 X 9 cranks through their paces all summer and here are my thoughts now on this drive train option “geared” (sorry for the pun!) towards the 29″er riders out there.

The cranks have performed flawlessly over the course of the test. Shifts have been good. Not super snappy, but not bad either. I used a SRAM X-9 shifter with the derailluer limited out to travel just far enough to allow the use of the 29T and 44T rings. I would characterize shifting performance as on par with what I had on the bike previously, which was a TruVativ Stylo crank. Pretty much standard for most trail riders.

The rings themselves have held up well, and they look great still, even after some pretty muddy sessions, what with the wet year we have had. A plus in the execution of the system for sure here. The arms with the ISIS interface is solid, and also came through looking great, but I will say that I am not one to rub crank arms with my shoes, so some folks results may vary accordingly.

Now, as for the whole 2X9 thing, these are my thoughts and not all necessarily related to this particular product. The way you use the front rings with the rear cassette is different. I thought a bit of a closer ratio between the two front gears would be optimal. I probably would go with a 42T versus the 44T that the cranks were supplied with. This would have lent me the opportunity to shift from the outer to inner chain wheel without shifting in the rear so much to find a close cadence to where I had been before the shift. At any rate, a choice in chain wheels to match from Origin 8 is in order. Obviously, a rider in a mountainous area doesn’t need a 44T so much and a 29T definitely isn’t going to cut it for some. Maybe a 36T X 24T combo? Well, I have written this before, but it bears repeating.

Also, it should be remembered that Shimano’s 12-36T cassette is on its way. This would be a perfect compliment to this crank, allowing a rider to stay in either the big ring longer, or in the saddle longer in the smaller ring, instead of walking.

Conclusions: The Origin 8 2 X 9 crank is a winner in terms of functionality, looks, and gearing for XC/light trail work. The system needs to have options, and it needs to have a lighter weight version. The two piece crank style perhaps could be that version. At any rate, this idea is well executed and when you consider the asking price of $100.00 or so, it becomes apparent that the value of this gearing option for 29″er freaks is great. Not everyone will love it from a gear ratio/weight perspective, but hopefully Origin 8 will address this in the near future. I can recommend these to anyone curious about 2X9 and that doesn’t want to spend a fortune on the experiment, or to anyone that just likes high value/low cost with good looks, good performance, and a devil may care attitude about the weight.
