Thun Bottom Bracket Cotterless 127/40mm Thompson Press-Fit

This Thompson bottom bracket from Thun is specifically designed for bicycles featuring a compatible Thompson press-fit bottom bracket shell and a cotterless square-taper crankset. The 127/40 mm specification must align with the original bottom bracket dimensions, making it essential to verify the old axle length and frame compatibility before placing your order. It is ideal for replacing a worn, loose, or rough-running bottom bracket that leads to play, creaking, or poor crank rotation. Please note that this is not a threaded BSA bottom bracket, so ensure compatibility with your frame type is thoroughly checked prior to installation.
