not too sure dudes could be wrong, but i reckon the stress goin through a dragster is a smidgeon more than what goes through your chainstays (mightymini's chainstays are the exeption), gotta keep things in perspective dudes.

Sanmarcopizza:
Lets face, I would have thought that the multitude of companies out there who powder coat their frames would know whether it was going to be detrimental, and if so would just paint them. You have quality manufacturers of low quantity hand built frames, such as Curtis & Pashley in the UK who have been in the bike building industry for 20 years+ and they powder coat rather than paint.

graeme:
Thinking about it, powder is baked at what, bout 180 deg if i remember right, anyhow, how hot does metal get whem you weld it? Loads hotter than baking temp.
So the frame would already be seriously weakened at the joins, and a few inch at least away from every join.
Dont bikes snap near joins?
This is all just typed as i think.
If bikes snap near the joins, it could be more evidence this is true.
Or, the fact that all chro-mo bikes survive after welding, means that the heat of power coating will have little effect.

TwoBobRob:
I wouldn't worry about it.  People have been powder coating MX bike frames for donkeys years, and you don't hear of any problems there... :)
