i just purchased a 2009 felt gridloc frame. this will be my first bike build from the ground up. i have been riding since i was 5 yrs old and im no dummy when it comes to servicing and repairing or upgrading my bikes. but i have never build one from the frame up.
the only thing that i am having a hard time with is the bottom bracket. here come the questions
i can assume that the threading will be ISO/British (sheldon brown says this is the most common)
do i have to use a square taper spindle? (according to the internet this is being phased out in favor of things like ISIS)
how do i figure out the proper spindle width?
will spindle width have anything to do with the chain line?
whats with the outboard BB? (i dont understand a lot about BB)
can i use any cranks or do they have to be more SS specific?
am i making this more complicated than it is? (i do that a lot)
additional info. i ride in the city, i dont do tricks, i dont do fixie (yet), and this will not be my everyday bike (i have a SS walmart bike for that). i would like to spend some money and buy nicer components for this bike, not to say price is not an issue but time is not as i already have a few other bikes i can ride. i want to make this bike truly "mine".
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
Your Felt is, without a doubt, English/ISO/British threaded. The type and length of the bottom bracket spindle will be defined by the crank you choose. Pick a crank and then select the bottom bracket to match.
1) You don't need square taper - you can use whatever you want.
2) Most frames these days are 68mm shell width.
3) Spindle length will determine your chainline.
4) You can use whatever crank you want, as long as its compatible with the BB you chose (i personally have the SRAM s100)
