I have a few questions before I order the spider.
1. Are the spindle lengths the same on road and MTB versions? My MTB BB is 73 and road is 68? I'd hate to find out that the spindle is too short during installation. Quick search online I didn't find anything specifying different spindle lengths with the 3D.
2. In the instructions there are spacers that are required where they are not needed on the road versions. Does the MTB spider dish so much that it will require those spacers?

I'm going to use a Raceface 30T single ring and use the Shimano 24mm BB thats in the frame.
I posted here because well...not too many people visit the MTB section.

Any help would be appreciated!
Thanks!!
