Road Crank for MTB
How would this work for a hybrid/commuter built from a 1990 Giant Yukon?

I've never used the Octalink BB before. Anything I need to know other than it takes a different tool to install?

If your frame's bottom bracket shell is 68 mm wide you will have no problem using the road crank and matching Octalink bb unless the chainstays are so fat or flared out that the larger chainring hit them. Octalink bbs take the same Park BB-22 installation tool as Shimano's square taper UN-series cartridge bbs and the arms install with the same 8 mm hex wrench but the crank arms require a specific puller or an adapter to allow the use of a square taper type puller.

but you really need to figure out, as Hillrider points out, if your BB shell is 68mm or73mm wide. that will affect what BB you need.
is there a crank on the frame now? the rings on the crank in the link are 30-39-50. most MTBs and hybrids in those days had 28-38-48 or 26-36-46 rings so there may not be alot of difference between the stock crank and the new one.
