Moving parts to a new frame

[Ryan82]

I have decided that I am going to buy a new frame. The current frame size I have now is 52. If I buy a 56-58 sized frame will all of the parts be able to fit onto the new frame? What are some of the things that I need to look for in buying a new frame? I use my bike primarily for road racing and long rides. It has Shimano Ultegra and a Kinesis fork. Is there anything else that would be a problem fitting a new frame? Thanks for your help.

The fork will not fit unless it is threadless and is cut really long and you are using a lot of spacers. But the new frame might not even take the same diameter steer tube (1" or 1-1/8"). This is not an issue if you're really buying a frame/fork combo (aka frameset) rather than just a frame.

New headset will be required if fork steer tube is not the same diameter or is of different type (threaded vs threadless). Not an issue if the new frameset comes with an integrated headset.

New stem will be required if the steer tube is threadless and not the same diameter or if it is of different type (threaded vs threadless).

The new frame may take a different diameter seat post. A common diameter is 27.2mm but not all bikes use that. Plus the current post could be too short if the 52 is non-compact and the 56-58 is compact.

New frame might take a different bottom bracket. There is English thread 68mm width (most common), English thread 73mm width, Italian thread 70mm width.

There are different types of brake caliper mounting. Recessed nut and hex-nut. Most bikes these days are recessed nut and short reach.

You may need longer derailer and brake cables and longer brake cable housings.
