Campy Record road cranks for fixed gear
I want to run an older C-Record road crankset for a fixed gear application.
Facts:
This crank requires a 102mm BB ISO.
The chainline standards are 41mm/46mm : inner/outer position respectively, per Sheldon.
I want to be at 44mm chainline.
Question:
So, can I buy an adjustable 102mm Phil Wood BB to skew the driveside over -2mm to get at my desired 44mm chainline? (Using the outer position.) All all Phil BBs adjustable?
thanks in advance.

HI, that picture is not from a C-record aka record-c aka record cobalt. The picture u have in there is a campagnolo record 2001/2005 maybe just one generation before campy came with carbon cranksets.
The campagnolo Record C uses a non symetrical BB which is 111 mms or 110 mm in lenght. Probably it is the same BB the Campagnolo Record Pista crankset uses, which is just 111 mms in lenght non symetrical.
Now, if you are talking about the campagnolo record crankset, yes the lenght of the axle is 102 mms. If you want to use that in a fix gear I would do this better, get a token 102 iso tapper that is way cheaper than the philwood for sure. The TOken is cheap but is good stuff, i been running one for 4 years and no problems. Then put the chainring in the inner position. Option number two, leave it as it is, and use a spacer in the sproket, u can run a 3+ mms spacer w/o any problem. That will straight up the chain line a little bit more but if you have sort of wide hubs like the campy ones or maybe the miche ones probably u wont even need an spacer or adjust a single thing because it should work just fine. Those 41, 44 mms chainline "its not a rule" all depends of your set up. Usually chains can work just fine with 3 or 4 mms off difference. I have run fix gear with usual 6 sp road wheels no spacers and the chain in the small chainwheel position, the chain worked just fine (road bike anyways) Which wheels are u using anyways?
Good luck

ultraman, thanks for the clarification on the campy nomenclature. it is indeed campy record; I believe it's from the 2004 vintage.
That's a great suggestion on using a cog spacer while retaining the stock BB. Do you know where I can get something like that? My LBS is in the dark about fixed/ss drivetrains.

HI again... Well your lbs is clueless just as me trying to write in english... hehehe nothing personal for the lbs ok?...
Well, some shimano MTB cranksets have them in the box, are made to space the BB cups, they should have a few for sure laying around... they come in the box but if they arent needed they keep them just in case somebody needs them. Are made of a super ultra hard plastic.

In the second link u'll see a few pictures of some sets that have them, for sure the guys have a few laying around. Eventhough they are for BB cups they wil fit more than fine the wheel threads..
Have fun
