M-Wave Carousel Bottom Bracket 122.5mm For. BSA/ITA - Silver

Give a tired frame a second life. The M-Wave Carousel BB Repair is a threaded cartridge bottom bracket designed to work in BSA (English) and ITA (Italian) shells—even when the threads are worn or partially damaged. A solid boron-steel axle and steel cups deliver everyday toughness, while the JIS square-taper interface matches most classic cranksets. It installs with a standard Shimano-type cartridge tool, and the set includes crank bolts, so you can get back on the road fast without hunting for extras.

- Restores rideability on frames with worn/damaged bottom-bracket threads, avoiding costly frame replacement
- Fits both BSA/English and ITA/Italian threaded shells for broad compatibility across road, city, trekking, and e-bikes
- 122.5 mm JIS square-taper spindle suits many drivetrains that need a longer axle for proper chainline
- Boron-steel axle and steel cups provide durable, no-nonsense strength for daily use
- Installs using a common Shimano-type BB tool; includes crank bolts for a straightforward swap
- A cost-effective “repair” bottom bracket solution for older commuters, winter bikes, and workshop rescues
