I came up today with a bike shop and frame builder here at Guadalajara, MX
At their facebook page they uploaded a picture of a Columbus Niobium Steel Alloy tube:
So where does the Niobium tubing stand compared to Reynolds 953 or even a Titanium tubes?
The guy can build you up a nice S3 frame material (I'm not sure what S3 stands for) for around 28,000MXP (1 USD ~ 13.5 MXP) frame and fork only.
I might go to his shop to talk about the tubing, etc of those builds.
I piqued my interest since I'm waiting to pull the trigger on a Motobecane LeChampion SL Titanium.
Any thoughts on those Niubium alloy tubes?
