Review on CURT 45770 Trailer Receiver Extension by Evan Hernandez

If you don't mind misalignment between smaller and larger tubes, then this adapter adapter is for you. But be warned - some other reviews noticed this and I skipped it before purchasing. The 1.25" pipe is not aligned with the 2" pipe. So if you're installing it to mount a 1.25" bike rack to a 2" rack on your car or truck, it's likely that the left side of the bike rack will be noticeably lower than the right side of the rack (or vice versa). How difficult is it to square two tubes in the manufacturing process? We see several.
