12 Titanium Disc Brake Rotor Bolts 12 Titanium Disc Brake Rotor Bolts. We love Titanium rotor bolts, and we think you will too. Nothing much to report on these other than that they are consistently in spec, hold the rotor tightly to the hub, and are lighter than the cheap-o steel equivalent. And because its jefe.bike, they're silver in color! Raw Titanium silver, no anodizing. They're 10mm in length with a T-25 head, just like the black steelies that you'll be removing from your wheelset, but much stronger, corrosion resistant, and significantly lighter at 1.3g per bolt. Why pay $50 for name brand Titanium bolts? These bolts have a standard rounded head and are machined specifically for jefe.bike from grade 5 Titanium alloy (Ti-6al-4v). They ship 12 to a package, so just enough for your favorite wheelset (6 per hub) As with all fasteners and mounts you're using on a bikepacking trip, we recommend a thorough and deliberate pre-treatment of blue thread locker of your choice. We have had good luck with branded Loctite 242 but everyone seems to have their own preferences in the area of thread locking compounds. Make sure your compound is fresh--and hasn't gone through a number of freeze-thaw cycles in your garage over the past winter, and use gloves when applying. Since you're going all out on a bolt refresh here, a little prep work can go a long way. These bolts are going to be working hard for you for a long time. Note--these come 12 bolts to an order. If you're loving these and are feeling the need for even more Titanium, you'll want to check out our 1 0x M5 Titanium water bottle boss bolt set.
