SKF bottom brackets are made entirely from stainless steel and aluminum – even the bearings – so they won’t rust or corrode. However, stainless steel is more brittle than Cromoly, so these bottom brackets only meet the “City/Trekking Bike” standards for fatigue resistance, and not the highest “Racing Bike” standards to which our other components are designed. This is the same for many other high-end bottom brackets, which also use stainless steel spindles, and SKF bottom brackets perform fine under most riders, including very strong ones. However, if you tend to break components, we suggest you look elsewhere for a bottom bracket.
Installation is simple, and requires only an ISIS-type bottom bracket tool. Do not use a “single-hook” bottom bracket wrench, as it can crack the hardened stainless steel of the BB shell.
The JIS taper is used on most Japanese and classic French cranks, including Stronglight and TA. It is also used for Compass René Herse Cranks.
