Hi Everyone,

I found a good deal on a used 29er with a 15" frame, however, I need a 19" frame.

If I bought a 19" frame of any other make, and took it to a lbs for assembly, would I have a complete bike? Are all the components transferable? I want to make sure I don't have any additional unforeseen expenses.

Thanks!

There will be differences, possibly in seat post and front derailler sizes (diameter of post and clamp respectively), the fork may be cut too short to fit in the larger size frame, the stem may be too short as it is sized to fit that size of frame, and the cables/hoses will most likely not be long enough to reach the more distant parts of the new frame or compensate for different routing.

Otherwise drivetrain, wheels, brakes, handlebar, pedals and all that shouldn't have any problems adjusting to the new frame.

Any part that isn't directly related to the size of the bike will work.

The problem is that many parts ARE specific to the bike and/or specific size.

15"-19" is a pretty substantial jump in bike size and if these bikes aren't the same brand or material than it might not work or be worth it.

The most important bit that more than likely won't work is the fork unless it's steerer tube remains uncut. Most large bikes have a much longer head tube than small ones and thus need the steerer tube to be long.

The other parts that may not work are the stem which may be too short, the seat post also likely too short and/or wrong diameter. Front derailluer comes in many sizes and can either be top or bottom pull. Fortunately all of these parts are relatively cheap.

So, it sounds like for a first-time 29er purchase, this is getting over my head.:madman:

Well I guess it depends on the quality of the parts you could use despite differences (wheels, rear derail, shifters, etc) and how much you are paying. If the parts are of higher quality and well priced, it might be worth the hassle of switching what you can and reselling what you can't use and essentially build up the remainder of your 19" frame.
