$0.00 Bike Setup: Kona Jake 2006. Summary: Destroyed it commuting to work in 2 summers (short Alaska summers). Same thing happened as stated in the other reviews: the crank arm would loosen up and need to be tightened every 3 miles. Inspection revealed the inside of the crank arm was worn down. I've put maybe 8 months on the bike, riding to work on pavement. I consider myself an average commuter/college student, and when averaging my experience with that of the other reviews of this product, I would say it will not hold up to daily use for very long. Strengths: Simplicity of attachment Weaknesses: Durability Similar Products Used: -

at eBay Favorite Ride: Any where, anytime Bike Setup: Soma Smoothie (Tange chromoly), Truvativ Elita 2.2 compact crank (50x36t), 11-25t cassette, Ultegra derailleurs and brakes, Xero aero rims, Easton carbon fork & carbon seatpost, Selle Italia Flite saddle, Performance Forte Ti pedals. Wt. 19.9 lbs. Summary: I bought this compact crank set because of the gearing at 50x36t and the fact that it had the one-piece crank with outboard bearings. As a 5' 8" rec-rider, the 52x39t had limitations for me. After making this switch, ride performance was vastly improved on the flats and especially on the climbs.
With the outboard bearings and GPX one-piece crank, I can do some heavy standing on climbs and it's smooth.
I've put around 3.5 K miles on them over the past two years--I have several bikes I ride through the year--and the only thing I'm noticing is the chrome-plating starting to wear off of the teeth. Strengths: 50x36t gearing is super for recreational riders. (Why did I wait so long?) The price is affordable. Weaknesses: For the price, none. (If I wanted lighter, I'd have to pay significantly more for anything in carbon. Nah.) Similar Products Used: Shimano Ultegra, 105, Sugino chainrings, Vuelta Chainrings, Rocket Chainrings

at Bike HQ Favorite Ride: Short Bays Bike Setup: Stock KHS-Flite700 Summary: Utter Crap.
Upgraded from the touro which came stock on my KHS Flite700. Very nice cranks for the first 4 months i used them. Very stiff and light for the price. Noticed a dead spot (as one other reviewer put it) in my spin and got off bike to find the crankarm coming loose. Torqued it up really tight with a large allen key again and same thing happened a week later. Tried again but it didn't even last the next ride.
Unless you tighten these cranks VERY often you will have trouble. The spline system for these cranks has been very poorly designed.
Bottom line if you want something that works get something with a proven spline system. The propriatary spline system used on these cranks is complete crap.
Or if you don't really like riding your bike and just want to torque the crank spline bolt for kicks then these are for you.
Also couldn't get warantee. Funnily enough a check for replacement arms for this setup yielded a 2-3 month wait... hmmm i "wonder" why Strengths: They looked cool Weaknesses: Spline system is complete crap.

at wheelandsprocket eba Bike Setup: 105 shifters and front der, sram 9 spd chain.
quattro pedals. Summary: wanted a compact crank that was "better" than my nashbar compact crank. also wanted silver. also wanted to try the outboard bearing cranks.
install was easy. i like the BB cup engagement system better than the ISIS/Octalink shells. seems to not strip as you install/uninstall.
after a shake down ride, i re-tightened everything. everything was great for a few hundred miles. i mean, i was seriously loving these things. then i started to notice a "dead spot" in my spin. when the left arm was at the top it felt like the pedal cleat was loose. at the end of the ride i tighetend everything up again.
next ride the left crank arm went loose after 2 miles. retightened it. loose in 1 mile.
i contacted sram about a replacement and they had me goin through the dealer. "we dont deal directly with the consumer." they also made it sound like i didnt install it properly. "you need to tighten the bolt after the first ride. it is a tapered spline system. if you dont do that, the left arm comes loose works aginst the BB interface. this basically destroys the arm and it must be replaced."
grrr.
i replied i had been very happy with the cx crank i had. and that i did tighten everything back down, to torque specs, after the first ride. and this was not stated in teh instructions sent with teh part, nor in any online documentation.
i still had to go through a dealer.
to wheel and sprockets, i say "THANK YOU." what other click and mortar store on ebay would help with a warranty?
four days later i received a rival crank arm and a rival crank bolt. this bolt is different than the original...
it is now installed, but i dont trust it.
will post a follow up... Strengths: cheap. they warranty their products Weaknesses: it broke. this seems to be a design flaw. if you read around, it seems several other external bearing systems have this issue. it doesnt seem to be a truvativ issue. Similar Products Used: 105 octalink, nashbar isis, truvativ elita cx isis.
