Box One 7075 Alloy Chainring Bolts
Box One 7075 Alloy Chainring bolt kits include five 8.5-mm front bolts, five 6-mm front bolts, and five 5-mm rear nuts, so they will fit just about any chainring/crank combination, including those with threaded holes.
As always the precision machining is second to none, great product!
Get what you pay for
I like how they give you bolt options for either thickness chainrings
Also works on Bullseye chainring spider combo
With Bullseye they do not sell extra chainring bolts, but these mate perfectly on the thread size.
