90 day unconditional money-back GUARANTEE!!!

In addition to proper technique we have found that a proper crank length is also extremely important to maximizing cycling power and speed, especially for time-trial type cycling. Our new M8 cranks allow experimenting with crank length as short as 90 mm so even the shortest rider can find the crank length that is best for them.

For us to ship you what you need the first time, you need to know what you need and order correctly. You need to be able to fit PowerCranks on your current bike and use your current chain rings. So, choose between the following choices:

1. Type of PowerCranks: Entry1, Entry5, Basic, X-lite, short lightweight PowerCranks (for those who want to race on PowerCranks and have figured out they also want the lightest cranks possible for racing), lightweight regular cranks, iCranks (PowerCranks with built in power meter and amazing technique software).

2. Bottom bracket type: Our standard is a tapered square. Shimano octalink V1, ISIS, and others are extra cost options. We can also fit PowerCranks on most of the newer BBtypes like BB30, BB90, BBright, etc. but these are so varied that you should contact us before ordering.

3. Color. Gold is our standard crank choice (afterall, we are the gold standard for training cranks). New for Model 8 Crank the black option is available for all models.

4. Dual mode option? New for Model 8 the Dual mode (locking) option is offered on all models. This option allow using the cranks as both PowerCranks and like regular fixed cranks and adds about 90 grams to the weight of the cranks.

5. 2 chain rings (standard) or 3 chain ring option.

6. Aluminum or composite (standard) spindle adapters. Composite is lighter and saves some money for the weight weenies and cost conscious. Aluminum is more traditional and stiffer and less likely to break in a severe crash. Our standard composite spider will accommodate 110, 130 and 135mm BCD chain rings. The aluminum spider accommodates 110 and 130 BCD chain rings. To use 110 chain rings requires using a shim to move the small chain ring away from the spider so the chain will drop down and engage the teeth (provided). For those who know they will be using compact (110mm) chain rings we offer a 110mm only spider to make shifting and set-up more standard at no additional cost.

PowerCranks™ Basic

The new M8 PowerCranks have increased the range of adjustability to 90-175 mm in standard 2.5 mm increments. The redesign has also dropped the weight considerably, being almost as light as our previous X-lite cranks. These are best for the very serious cyclist who want to get everything possible from the product or those who need to change to very short cranks frequently and easily such as rehabilitation clinics or adults sharing an exercise bike with small adults or children. As before this model comes with the dual mode and black annodized options available.

Rental program

The rental program is for US residents only. This is for those who only need the PowerCranks for a limited time or who want to try the cranks for a more extended period without committing to a full purchase. An example might be someone needing to rehab after surgery. Or, someone who has previously trained on PowerCranks, sold his cranks, but looking for a "tune-up" with them during the off season or preparing for a big race. Or, someone wanting to experiment with crank length before committing to new cranks of a specific length. A portion of your rental fee can be used towards the purchase of new cranks from us. Price will vary depending upon capability and length of rental period. Small extra charge for Shimano/ISIS adapters.
