ok. did a few measurements on the concorde. ('94 bike with campag Mirage/Avanti groupset). I came to the following chain line options with the existing BB and existing chain rings.
Using outside chainring (52) the chain line will be 50.25 > 50mm
Using the inside chainring (39) the chain line will be 43.25 > 43mm
Disregarding the .25mm to measurement error.
My wheel spacing's are as follows; front 100mm and rear 130mm. I went into my LBS and they chap there was sure it should have been 135 but I measured again and it is really 130mm
So the question is what do I buy a 120mm rear wheel with some spacers or is 130mm a standard width?
I am thinking of using the existing rim and change the hub for a flip flop version. Any wheel builders near Maidenhead? Any advice on hubs? Or should I get a complete wheel and just sell the current wheelset?
Once things are ready and after the last sportivo in October I will start the conversion to fixed wheel / flip flop. Planning to go fixed wheel but will use the flip flop option to revert to single speed if I don't get on with it.
