front brake disc studs

[Demongroover]

Replaced mine 3 years ago when they went orange. Did the 85 mile return trip to Pro Bolt who supplied me with A4 stainless for the discs, caliper mounting and pinch bolts and the fork leg pinch bolt. It was over £60 if I remember correctly but are still looking as new. The guy there said I had to have A4 stainless or titanium (at twice the stainless price). Surprised there not doing them any more!

Most bike stuff is A2 stainless and is perfestly good enough and will not rust.
A4 is marine grade which may explain the price!

....and is no stronger than A2 AFAIK
