So you want shorter crank arms – now what?

 

Continued from Are your crank arms too long?

Ok, I have decided that I want to replace the standard 170 MM  cranks on my Slipstream with 155 MM cranks more appropriate for my Hobbit legs.

So I Googled and found almost nothing. Looks like the shortest commercial Road and MTB cranks are 165 MM. There are 155 MM and shorter cranks out there but they are BMX cranks and cranks for kid’s bikes. None of those are drilled for a Triple Chain Ring. There is no way I can give up my Triple.
