replacing a frame
The other day the frame on my fully rigid 98' GT bravado snapped. The nice people at GT have offered me a Avalance Expert frame at cost price so I think this may be a good option rather than trying to have the frame welded and it potentially failing again. It also means I get a much better and lighter Al frame.
Is it possible to put my rigid forks on the avalnace frame or is the geometry all wrong? I use it for road riding with slicks, hence rigid forks. I would prefer to buy a true road bike but don't have a spare £600-700.
How tricky a job is it to swap all the parts of the old frame onto a new one? Would it be easier just to get my local bike shop to do the job and save a lot of hassel? I am guessing there are a few special tools needed for the job. What parts are likely to be not compatible with the new frame? The current bike is a mix of 98' shimano LX and XT. I am also guessing that the front mech may not fit if the downtube is bigger.

If you are unsure what to do and how to do it I would strongly recommend taking it to a shop. There are some specific tools needed. There might be a problem with the fork steerer tube size which might mean a new fork and stem. Thats only if the current is not 1 1/8 inches and the new probably is. Also check the size of the seat tube. Other than that everything should fit.
Things to check that may not switch over-

-front derailler clamp size may be different.
Also, if the geometry of the new frame is different, you may end up wanting a different length &/or rise stem.
That is cool that GT (now Pacific cycles?) is warrantying your frame, since GT's changed hands a bit over the years.
it will be cheaper to have a bike shop change over the parts than to buy all the tools required (or close in cost), unless you plan on doing lots of bike work in the future.
