|After a topic was suggested about these I thought why not start one.
After using mine I have found I really like them. They force you to pedal in circles using your hip flexors and glutes very hard. I have only used them on rollers when I get a chance but find them great. I'm even thinking of bringing my second road bike to Australia with me so I can ride them.
What do people think the pro's and con's of these are?

|I've read some tech writeups on www.cyclingnews.com, and I think Lennard Zinn's discussed them in his tech columns at www.velonews.com.
Feedback seems very positive, but I'm conservative and a cheapskate, so would require a great deal more evidence before spending money.

|I've seen some personal accounts (and was an insider to a complete conversion from pundit to advocate last year) in the triathlon world. Seems to work pretty well, even amoungst highly trained cyclists. Interestingly enough, it appears also to improve running efficiency even more.|

|I've been using them full-time for two years. I have never seen any published studies on their effectiveness so I shy away fom making claims of improved performance. I can, however, state two facts concerning Powercranks that don't require any studies to prove. 1) They will clean up your pedal stroke and train you to pedal in circles. 2) They will strengthen your hip flexors. Now... it's up to the studies to prove that a "more efficient" pedal stroke and stronger hip flexors equate to improved performance.
I don't recommend this to everyone who uses Powercranks but they also strengthened my abdominals. Sometimes, if nobody is around, I will pedal with both feet together for distances of five to eight miles. This is effectively the same thing as doing crunches. That way, I don't have to do abs when I get home.
