Genuine Wheels Manufacturing spare, or a great tool on it's own, for removing SRAM DUB 29mm bearings
To remove sealed bearings you will need the correct size extractor, 8mm & 10mm wrenches (for small sized Extractors) or 13mm and 1 wrench (for large sized Extractors), hammer and punch
The correct size extractor will fit snugly into the inner diameter (I.D.) of the sealed bearing you wish to extract
Place extractor into I.D. of sealed bearing until it seats flush with the shoulder of the Extractor
Tighten nut with wrench while securing extractor with other wrench. Tighten nut until the extractor is firmly in place within the I. D. of the sealed bearing
Once the extractor is secured, align a punch with back side of the extractor
Gently tap on the punch until bearing is removed along with the Extractor
The bearing is now removed. Install new sealed bearings with a Wheels Mfg PRESS-1 (rear hub & bbs) or PRESS-2 (front hub)
