70mm and 68mm axles only differ in the length between the bearing races. Using an English axle in an Italian shell would mean that the adjustable cup sits 2mm further in that it should, which could mean there's not enough threads for the lockring. Its the actual axle length and taper you need to match to the crank. I think the Campag record cranks changed the BB lengths a few times over the years it was produced, but it should be a 113mm or 115mm ISO axle for the correct chainline.Smithy78 wrote:No major dramas, although I am confused by the bottom bracket, as it is Italian threaded but took a 68mm spindle. When I put a 70mm in, the crank was too close to the chainstay plus the adjustable cup was sticking a long way out of the shell.

I thought it may have been a compatibility issue with the crank, but with the 68mm spindle the adjustable cup and lock ring sit perfectly. I checked for the "correct" spindle on Velobase before I purchased the Italian one as well, to ensure I was getting the correct one for my crank.QuangVuong wrote: 70mm and 68mm axles only differ in the length between the bearing races.

Funny thing is that when I bought the frame, it already had this Italian cup / English spindle installed (thought it was just an ebay seller installing the incorrect spindle) and I believe it had a Campag crank installed previously (was following this bike on ebay for a while before the seller gave up trying to sell it as a complete bike and sold the frame only)
Ran the ruler across the shell, and it is definitely 68mm in width. Would this indicate that it had been machined back at some point in it's life?

Pic attached is what I believe to be a Tecnos Art Decor. Always wanted a Colnago.
It is somewhere between Belgium and Aus as we speak.
Not sure of gruppo yet so will wait till I get the frame here first. So excited.

As for Shimano, I'd go with either 6500/6600 Ultegra or 7700/7800 Dura Ace - still pretty easy to find a group in good condition on eBay or in various for sale groups.

I have a Campag Centaur 10sp here in silver. Also have a 9sp dura ace 10sp in silver.
Have a set of campag record hubs in mavics looking for a bike to go on. Have a complete 105 groupset also, but it is grey so probably wont match too well. Decisions Decisions but time will tell.

I have a Tecnos and its a quick frame to ride. I believe they were Colnago's lightest production steel frame and the early ones came with a rider weight restriction. I think the restriction was limited to 170lbs rider weight for the Tecnos frames made with Columbus EL/OS tubes (up to the year 2000). I'm well above the weight restriction and have had no issues as yet.

Leaning towards a polished 10 sp silver ultegra groupset at the moment, mainly for compatability with its stable mates.
Cant wait.

I seek help if someone can help ID the frame. Have been trying to search for pics for reference whether it is a master or master piu and a possible year. The brake cable goes in to the frame on top. Any help will be much appreciated.
I plan a modern build on it and use it as a secondary bike.

I think I have the Colnago bug...
Started with an entry carbon bike - the ACE in matt black (yes I know - not a great colour but only one available at time). Quite nice for my style of riding and managed to compete a couple of AGFs on it
Then found a nice lavender coloured steel Colnago frame advertised as a Master later eighties, but more recently correctly identified as an ESA Mexico (has 6 crimps in tubing). Built up with Campy Chorus parts with newly built Mavic Open Pro wheels - very nice ride. Love the colour of this! Also have purchased ESA decals to install.
Next...
Just took ownership of a restored Master frame...
Gradually collecting parts - Record Titanium group set, Campy delta rims, 3TTT Ergo Due bars and honey Rolls saddle. About to start assembly
What next?
