Isn't it an American produced tubing anyway?

Don't forget the alternative to 953 stainless is Columbus XcR Stainless... made in Italy... makes a wonderfully light and strong frame. But iirc neither are designed for MTB builds... guess they can be used for lightweight XC use, but nothing burlier. XcR brought out an oversized tubeset last year officialy for road use, but guess it's potential for a MTB frame build.

had a 953 Genesis MTB made a couple of years ago, rode nicer than anything else i'd ridden inc a ti version with same angles, passed CEN but broke in further testing ( it was of the earlier-produced 953 tubesets so may well have broken on the trail.
Some improvements in production method and metallurgy mean it's far less crack-prone now though.

The reason we're not seeing mtb frames in stainless is that the manufacturers aren't producing the butting profiles suitable for mtb frames yet. As it is a new (difficult to believe I know) material for bike frames, all the manufacturers have started by producing road tubing only. There is no reason other than economics and market testing as to why mtb tubing isn't produced in the suitable butting at the moment. It will happen.
On the frame builders forum there are a few custom builders who have started to incorporate stainless into mtb builds, but they are using a mixture of steel and stainless to produce a frame of the correct butting strength. Another issue these builders have found, is that the tubing isn't as easy to bend and shape (chainstays/seatstays) so again it is necessary to wait for the correct tubing to be manufactured with the tyre clearance for mtb's.
The ultimate would be to fillet braze the tubes with silver solder - none of this vulgar TIG welding!
Again it boils down to cost.

KVA do heavier guage than reynolds as well as plain guage tubes. At NHBS this year there were a few KVA MTBs.
The difficulty in bending to shape is a valid point and it will be interesting to see what happens with further tube shapes and profiles.
it needs the same carefully purging as ti to weld
does this apply to brazing of 953?Posted 1 year ago # -
Flippin nora, been looking at Mercians 953 frames and forks. I really really want one, but it would be so expensive, you would have to kit it out with top kit.
So I've stored this in the **** bank.
