Park Tool BMT-1 Tire Bead Breaker
Save your thumbs and retain your sanity. This Park Tool tire bead breaker quickly and easily unseats virtually any bicycle tire bead. It works particularly well on tight-fitting tubeless systems.
- The locking jaws of the BMT-1 are tightened against the sidewalls using the large adjustment knob, firmly squeezing the tire body
- Once the long, strong handle is pulled laterally in either direction, the bead is pulled away from the bead seat and toward the center channel
- This allows for removal using a tire lever or other method
- Nonmarring jaw covers protect the rim and tire from damage
- Compatible with tire bodies from 23 mm to 78 mm (0.91 in. to 3 in.)

Works well, but big and heavy.
BMT-1 works well to break the bead from the rim without scratching (or worse). Before I purchased the BMT1, I kluged a similar tool that was quite tricky to use. BMT1 is heavy (shipping label says 2 LBS) and physically large. Probably not going to want to haul around on every ride. Related opinion: Tubeless tires are a giant pain and should be avoided. In my case, I purchased a bike with tubeless-ready rims&tires but with tubes(absolutely worst combination ever). I didn't know what that meant until I got my first flat. In addition, the tires assimilate small pebbles - lots of slow-leak flats. Very frustrating.
