Bianchi fixed gear build - advice

[aea730]

I'm just about to embark on a fixed/single speed build using a Bianchi Super Pista as the frameset.
I'm comfortable actually putting it together but I can find little information on the technical elements such as crankset selection, size, getting the chain line right. I'm fine with the finishing kit, brake etc it's just the drive element of it that's troubling me at the moment.

Has anyone any experience with fixie building

First of all you have a track bike, not a "fixie". Treat it accordingly

Are you intending to use it on the track? that will impact chainset crank length choice as most tracks wont let you run anything longer than 165mm. If you're not, head over to www.velodromeshop.net and pick what you want. The Miche Primato is good standard stuff,

Useful info on chain line alignment here

You'll need a 1/8th chain, i use KMC and havent had any issues.

Sprockets are your choice too based on preferred gearing, I run 48:14 on the track but you may want something like 48:16 for the roads. Get a few of the lifeline ones from wiggle and trial them. Buy an expensive lockring (£30+), they dont shred when you try to tighten/remove them like the cheap ones do.

Does the fork have a hole drilled for the brake?

Thanks Pablo, apologies for the incorrect terminology. I've no intention of tracking it so from that perspective the crank length isn't important, does the track nature of the frame lend itself to a shorter crank, obviously the seat height will be a little more with a shorter crank.
I'm looking at sram omnium for the crankset, I'm guessing I just fit their standard bottom bracket and make the chain line adjustment on the back end shimming the sprocket to line up.
I will have a look at the links you posted.
The front fork is drilled for a brake but the the seat stay bridge isn't. Given this and the track nature of the bike I'm going to run it fixed wheel to start with, I've run a pearson touché fixed before so got some idea of the "experience of terror"

Well the frame has landed here from the states according to USPS tracking. It's now with parcelforce at Coventry central hub "awaiting contact re duties" see what that brings !

Well after a few days of sourcing the last bits and making the best of the planetX sale the bike is complete. I'm on 49/18 gearing at the moment so will see how that goes. Also I've not settled on steerer length yet so left a bit on until I'm sure
