Shimano BB-LP25 Bottom Bracket 73mm x 114mm Square Taper MTB Vintage Japan

Shimano BB-LP25 cartridge bottom bracket, Made in Japan. Shell width 73mm, spindle length approximately 114mm (measured), BC 1.37×24 threading, square taper. Fits a wide range of vintage MTB frames running a 73mm shell. Condition is good and serviceable — it turns and functions as intended, but it’s not butter-smooth. Perfectly fine for a build, not a candidate for your XC race bike. Threads are intact on both sides. What you see is what you get. Specs: • Model: Shimano BB-LP25 • Shell width: 73mm • Spindle length: ~114mm • Thread: BC 1.37×24 (English/BSA) • Interface: Square taper • Made in Japan
