Are Dura Ace 7950 Cranks Compatiable with Psychlo X frames?

I would like to run these cranks with cross chainrings. The mechanic at the LBS says that they are two narrow. BTW, I am running a Chris King outboard BB. The frame size is the 58 if that matters.

Anyone have experience putting the 7950 cranks on their Psychlo X.

I'm running a custom geometry Psychlo-x frame with 7650 stock durace cranks (50-34 durace rings), king bottom bracket and SRAM XX long cage derailleur with SRAM 11-34 cassette. No problems. It's in the moots gallery on page 4 set up as a touring bike

smithm7,
What year is your Psychlo X? If you have the version with the shaped chainstays (flattened) they will work. If you have the round 7/8'' stays on the older models they will not. The bb is fine, the chainrings are fine.

Let me know what year your frame is and if possible the serial number (under the bb shell). I'll look it up for you.

I won't be in the office until Monday, but you can call the Moots office with the same info if you like.

Thanks,

Jon@Moots
