1) If the frame's dropouts are made of relatively thin metal (like, stamped from plate metal), then your rear wheel's quick-release skewers may not be able to clamp the frame as intended. That can cause the rear wheel to slip and jam, so keep an eye on that.

2) If the frame is made for 126mm hubs or narrower, then expect some resistance when you're trying to get the rear wheel into the dropouts.
