Excellent Overall, One Small Issue

Great if you run short stems and ride rough. I've been using one threaded into a standard depth star nut with the supplied 30mm M6 countersunk bolt, which works great and firm. However some bung and extender wedge designs require a longer bolt. I splashed out on some 40mm A4 stainless bolts and problem solved. Maybe you can add 40mm bolt as an option?
