Trying to learn more about cranks, there are so many damn options. What do the terms standard and compact mean in reference to cranks and what is the difference? What are the advantages/disadvantages? Thanks

compact runs a 94 mm spider while standard runs a 110. Road spiders are 130. compact allows for tiny inner chainrings whilst most standards allow 48 outers. Hard to find a 48 in compact if at all. If you go MTB for cx standard would be a better choice IMHO

I think that standard is probably better as well since it allows for larger chainrings. Still, there are reasons for choosing compact. First, they allow for easier and faster shifting since the rings are, overall, smaller. Also, because the overall diameter is smaller, they are lighter than you standard crank, though probably not by any significant margin. Also, I've read that compact cranks are stiffer than standard, though this I can't really confirm. Anyhow, I remember when I started with all this stuff a couple of years back, it really gave me a headache trying to find out all this stuff. If you want a good explaination of cranks, than go to These guys went out of business years ago but for some reason their site is still running, and it is full of good explainations about all parts of a bike.
Thanks for the info guys...nmsfrider
