Carbon Frame alignment.
#1
Hi Guys,
just a thought. I have had the time to repair a BB and a rear mech on carbon frames for friends. I used the park tool for checking dropouts on the rear and the front fork and have found quite an offset. Maybe not to feel as you ride but the wear on the tire and the wheel bearing must be a problem. On a steel frame this is easily repaired using the tool, but a carbon? Has any body else come across this? Thanks and ride safe.

Are you, perhaps, over-thinking this one? I wouldn't touch it with a Ten Foot Pole!
Excluding some very "inexpensive" CF frames from the Asias, most mfr's go to great lengths during the R&D phase to ensure that, once the mold is made, the frame emerges 'as per spec'. A mold (say, a Trek Madone 3.1 in the 56 cm size) may cost as much as $8,000 to have made. JUST for that 56. All other sizes have thier own mold.
Hmmm.. how did I get off on that tangent? Anyway...

No. Don't try to reshape anything carbon.

My thought was that someone had come across the same thing. I am not talking about 8000 dollar frames. I was mentioning a normal frame ( made in Asia ) that had this problem.Any frame out of true is a problem, be it carbon, steel, whatever. I am not over thinking, just the way I have approached repairs for the last 25 years. Thanks for the tip not to reshape carbon.

Not talking about an $8000 frame, brother. An $8000 mold that the frame is made in. And 25 years is a good number. On 20 myself.
