Rampage , Magnet is the best way to work out if it is steel or titanium.
The M95x cassette has some of the cogs made from titanium, not all of them.
Thanks rampage, managed to find some information about the M950/1/2 series cassettes , from the information gathered, the M950 series was first launched in 1996 , so that dates the cassette to be around 96-up to as early as 2002 if it is a M953 ?
The rear mech is a RD-M739 Xt unit so that's around 1995 , the cranks FC-M900 places them 92-95. so quite a mix of bits and pieces really.
Am I right in thinking that V brakes were on most bikes after 95/96 ? is so that would date the frame before this as it has a cantilever brake guide on ?
Trying to find out the years columbus max or tubes were being produced and what other makers produced a frame in this tubing ?
raidan73 , I understand what you mean, all the t max frames I've seen, the chainstay seems to 'piece' the top tube
also raidan you said , "No apparent mounts for racks etc would suggest it was designed for a purpose though.' you thinking something like a show bike , like they used to show at durango/bike shows and the like ? or custom built perhaps/ one off ?
Ridin like it was 1992
