Race face turbine LP, which one?

I'm trying to figure out what I need. This is my 1st time trying to build a bike up from parts.

I'm Looking at http://www.jensonusa.com/store/product.asp?number=12045&sc=mr08&x=y#Description and
http://www.beyondbikes.com/shopping.asp?type=11

There's: compact drive vs. standard drive isis vs. square
94/58mm and 110/74mm BCD configurations

What the hell is the difference?

Thanks, Bruce.

Compact drive and 94/58 BCD are the same thing. Compact drive refers to smaller chainrings and
sprockets than standard drive, saving you an ickle bit of weight and giving more ground
clearance too.

BCD is the bolt circle diameter, this refers to the diameter of a circle drawn so that it runs
through the centre of the chainring bolts.

Isis is the new funky way of holding your cranks onto your bottom bracket, using a splined system.
Square is ye olde system with a tapered bottom bracket. Whatever you do here, make sure that your
bottom bracket and cranks match.

94/58mm is "compact Drive" Go compact if you wat to run lower gears (like a 22T or even a 20T
inner ring)

95/74mm is "standard drive" for bigger gear at the cost of not being able to go below 24T for inner

ISIS VS Square.... ISIS _ROCKS_ however they can be a real B!TCH to fully seat. Race Face has now
revised thier instalation procedures. (seat as well as you can, go ride, tighten, ride, tighten,
repeat untill crank is fully seated.)

all that being said I ride Race Face ISIS Compact on everything (x-ceptin' for the SS) and could not
be more delighted.

Perfect, Thanks! That's exactly what I needed to know.
