Wanyifa 4/10pcs M6 Titanium Nut Full Length 13 15 17 23 25 31.5 33 35mm for Road Bicycle Brake Caliper C Clamp Fix Ti Parts

I had huge fun replacing almost all the nuts & bolts on my bike(s) with titanium ones. I mostly stuck to the brands Taimeili, Wanyifa and XMSJ Titanium Accessories. Through spark testing I can confirm it's at least *a* type of titanium alloy (bright white sparks), and nothing failed until now, so maybe it's actually grade 5. Adding everything up, I was able to save around 58g on one bike through titanium bolts for ~115€ (using coins and Choice Day-/Singles Day-/Black Friday-coupons)
