Anyone know of good sources for Sources for short cranks?  Im looking for a short crank arms in the 150MM-160MM range.  I want to see how my long legs respond to a short crank.   Terry
 

Mark Stonich of bikesmithdesign would be my recommendation. I was referred to him from folks here as well as the Bacchetta forum.  I recently ordered a set of 150mm SRAM APex and 36/52 Rotor Q rings and will tell you it has made a tremendous difference for me.  A conversation with mark will help you better understand what's happening with you, why you should make the move and how to adjust your ride upon receipt.  Great guy and very knowledgeable, suggest you check it his web site for the basic questionnaire before Contacting him as it will help to educate you in the process and help the conversation along.
