    Short Road cranks

    So the market for short road cranks is non-existant and after weeks of searching on eBay I decided to go ahead and try to cut come down. Shimano cranks were out because I didn't know how big the cavity is inside the arms. I thought about some older suginos but I wanted compact cranks for him so most of those were out. So with the help of an MDF jig, a drill press and some taps my son and I came up with some 152 Campy Athenas.

    Glad you made a go of it. Any pictures of the arms in the jig?

    Maybe you saw this link, or maybe not, before you started the project.

    I'm putting Sinz bmx cranks on my son's new road bike. 110bcd, so you can run something like 36/46 gearing.

    Short Triple Chainring Cranks

    I had seen those cranks before but I hadn't looked at the page in quite some time. I figured for the premium that he wants for the cranks (and he deserves) I could buy the taps and do some myself. Plus they are going on a Merckx so it had to be Campy I don't have any pics of the Jig but I am going to cut down some tandem cranks also so I will get some pics of that in a couple of weeks.

    I thought about those but I wasn't sure what the chainline and Q-Facter would be like. My son has some 152 Sugino mountain cranks on his mountain bike and I was planning on just getting another set of those but when I fitted them up to the road bike they were pretty wide. I was a little concerned that the BMX cranks may fit similarly but I don't have any experience with them.

    I did the same thing (with the same reasoning) except without a drill press on an older set of Cannondale cranks with a removable spider. Between that an old compact mtn 5 arm spider, he is running a 32/22 double on the front of his hotrock. A nice upgrade.

    You did a nice job on the mod - looks good!
