with lock and chock These adapters are great for bikes with narrow tires. They do not work well with Bike Pro chocks, the difference between chocks is negligible and noticeable when using these adapters.
The bike tire didn't fit on both sides, which kept the bike in a high front wheel position. Removed one from each side and they fit, but still had plenty of side-to-side movement. The bike without it is about the same. save your money
