BSA 68/73 Threaded BB with ultra low-friction Tier-1 NSK VV 6805 Bearings

Quality multi-piece BSA 68/73 mm Threaded BB upgraded by Hogtown Spokes with genuine Tier-1 NSK VV 6805 oversized bearings. These bearings are from NSK’s ultra low-friction (VV, non-contact seal) series and represent a notable improvement in quality over the bearings supplied in typical bottom brackets.

• Fits Shimano Hollowtech II (including 12-speed) MTB cranksets with a 24 mm spindle

• Includes (2) x 2.5 mm spacers - depending on whether your frame is 68 or 73 mm wide at the bottom-bracket shell

• Employs “top hat” reducer bushings that sit inside the bearings’ inner races to further protect the bearings against muck and foreign matter and allow for use of these oversized bearings (25 mm ID) on 24 mm Shimano spindles; the result is a stiffer, more durable bearing stance for use with Shimano cranksets

  **(1) EXTRA SET OF TOP HATS IS INCLUDED**

• Buttery smooth, lasting cartridge performance

WARRANTY: Supplied by Hogtown Spokes, exclusively, and extending for one year from date of customer purchase against manufacturing defect and normal workmanship. In reality, properly cared for Tier-1 BB bearings should last much longer than this. Avoid sending wash spray directly into the bearing cups.
