I had a training partner last year that recieved a free pair of power cranks and trained on them for several months. I used them for a couple of training rides. I found that they do what they are meant to but I think that they are more a gimmik than anything. Yes, they will make you use a circular peddle stroke, but I think they make you too dependant on you hamstrings for power, and in triathlon we need to use less hamstring and more quad. I think that doing drills(one legged pedal for 1 minute at a time) can help you to achieve a more rounded pedal stroke. You just have to be diligent, that is all the power cranks really are, they make it impossible to forget to use a round stroke. The biggest downfall of the crank,(besides the price) is that they make a 25 mile ride feel like a 50 mile ride. Even after the 3 week braking in period. They take way more out of you legs than it is worth. I think they can be good if you have two bikes and have the opportunity to ride the cranks 1 or 2 days a week, but the do not allow you to put the miles in for a proper base, and are definatley too draining for speed work or interval days. The guy who invented them is quite a salesman and it is hard to say no once he gets You believing that you "can't be competitive in the next 5 years without power cranks" If you have the money, try if not just use those drills

Sorry to hear they didn't work out for you. I've been using mine for nine months and have seen some nice improvements. The break-in period for me was about 1,500 miles. Now I can barely tell the difference between these and regular cranks. Just wanted to touch base with some other users to see what sucess they've had, or not had. Thanks for your input.

I've been riding them 7months, and recently took them of to start racing summer tri's. I've ridden some very long miles with them, including a 3day 330km trip in the Rockies, with lots of long hills. It's interesting to note how you become totally used to them after 2-3months and you really don't think about the 'pulling' part of the stroke. As per making you faster, the next few weeks and races should tell, but I almost never get dropped on hills now and I'm feeling very strong. After taking them off, I couldn't help but notice how much smoother and easier it feels at high cadences, riding at 110rpm is completely comfortable with a low HR. I think it will take another season to really see the benefits (nothing like this will make you fast overnight), but I really wouldn't worry about losing base fitness if you start on them right after race season (sept). I think most people would tend to be impatient and feel they must ride long, fast and hard to quickly, and they then get discouraged. Don't expect to be able to ride 3-5hrs for 3-4 months, and even then, your hip flexors will be bagged. Relate it to swimming, do you think you could change your stroke (or learn a new one) an become way faster and stronger 1 season? No, but long term the changes make a significant difference.

You mentioned how smooth your cadence was at 110 rpms... When you started training with the cranks did you notice it was difficult to spin at 90 to 100 rpms? I'll be switching back to standard cranks in mid July and I'm wondering how difficult it will be to jump back to 100+ rpms...

It was surprisingly easy, and instant (no practice sessions). I just jumped on to do an easy spin ride and was trying to bring my heart rate to a mid/easy point and I just kept bringing up the cadence. No fatigue, no bouncing, my spin scan was in the 80+ range on the computrainer, and I got to about 112rpm before I hit my desired HR. I was able to hold it there for the rest of the ride. It's a wierd feeling the first ride when you switch back. When you stop pedaling, it's like someone kicks you in the bottom of you foot, because your so used to both feet going to the 'bottom'.
