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 > 43mmDisregarding 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.

I am planning to convert my old road bike. (see other threads). I have two options for the wheels, buy a new set or so something with the existing set. The rear wheel is a rigida rim with a campagnolo avanti hub. Is the cheapest option to buy a new hub with spokes and use the existing rim?
How much would a shop charge for lacing a hub into a rim?
I am also keeping an eye on the used forum if an affordable rear wheel pops up. Ideally I want to run a flip flop hub. Want to have the option to turn to single speed if I end up finding running fixed gear dangerous on the road biased frame with 175mm cranks.

Just thought I ask. I am looking into the bits and bobs needed to convert my road bike to fixed or single gear. The bike has Campagnolo avanti 175mm cranks and a road geometry is this a recipe for disaster and should I take into account getting smaller cranks if I plan to go fixed gear?
thanks

Just got a reply from velosolo.....won't work.
Regarding the spacers on the rear we often get asked if our SS spacers are compatible with Campag hubs - they are not designed for Campag but some riders have used them successfully. Unlike Shimano, Campag have changed freehub OD dimensions over the years, the ID of our spacers is 35mm so please measure your hub with a vernier guage if unsure. We do not have any Campag specific cogs I am afraid.
It's a shame since the hubs are fine. The quest continues.

Thanks for all info, I send of an email to Velosolo to see what I need to make my current wheel a single speed (thanks Sergeant Pluck). Will probably do what you suggested wiganwill and use my 39 ring in the front and gear the rear accordingly. I will also look at buying a rear wheel.
The plan is coming together.

The rear wheel is a rigida rim with a campag avanti hub with 8-speed cassette. Is it possible to use that wheel? Is it as easy as taking the casette off and replace with a sprocket (and re-space and re-dish)?
I do think I would like a flip flop set up first to get used to single speed work.
I will have a look in the classifieds for a rear wheel. Thinking of 48T in the front and something like 18/16 for the flip flop. Or anyhing else that gets to that combo.
Feel free to send info to me...
What are good wheels to begin with?
Cheers

OK, am going to get a new geared bike via cyclescheme so I will be turning the old beast into a fixie.
What do I have: Concorde build up with a mix of Campagnolo Mirage and Avanti, bought around 1995. The frame spacing is 130mm.
What would you recommend to spend on wheels (I've seen Wilkinson wheels for a reasonable price <£100).
Would the crank at the front work or should I replace it with a new one including a BB.I've attached a pic of the rear of the frame to show the drop outs - are these ok for a fixie?
Just after some advice for this particular frame. Hence the pics.
Thanks,

I've got a conversion planned, would you replace the hub in a excisting wheel or would you buy a new wheel?
I've got an excisting wheel (rigida rim with campagnolo avanti hub) and am thinking to get my LBS to replace the hub for a flip flop hub (Dia Compe Gran Compe Rear Hub). Needs to space out to 135mm though.
What would be the cheapest / best way of doing it. I can't do wheels so would rely on the LBS to do the work.
