Enduro 3903 LLU bearings
these BB's are sure to stand up to the abuse of daily street use. On
our test BB the spindle weighed 152 grams and the whole setup came in
at 226 grams. Use the bolts from your existing cranks, or these
if you lost yours. No proprietary tools needed, Park
BBT-22 and any lockring tool
is all you need to install this BB.
