Short Cranks

More and more riders are discovering the advantages of using shorter crank arms, especially on recumbents and triathlon bikes. However they have been stymied by the lack of reasonably priced, short cranks, capable of accepting small 3rd chainrings.

Of course shorter riders, on upright bicycles, can also benefit from short cranks. As well as anyone with a leg length discrepancy or range of motion limitations

Knee pain

Triathletes wanting a more aerodynamic riding position

Range of motion problems.

Can't spin long cranks efficiently?

Tandem stoker isn't comfortable spining as fast as captain.

Short cranks make some people faster.  Could you be one of them?

Smaller fairings for HPV racers.

Toe/Wheel overlap (Heel/Wheel overlap on SWB recumbents)

Short legs or different leg lengths.

I’m a slow, arthritic typist, with many demands on my time. So I don’t want to ask questions and have to ask more questions based on the answers. And have to ask more questions based on those answers etc. etc. etc., in order to determine what you need. And often more difficult, determine what will work on your bike.

So before contacting me about short cranks, please read Answer any questions and follow any links that apply to your situation.

I am able to start shortening cranks again, after knee replacement surgery on Feb. 8th 2024. 

Over the last 20 years I have helped about 2,000 people, with an amazing variety of reasons for needing short cranks. Whatever your problem, I've probably solved it for someone already. If not, I love a challenge.
