ah the possibilities.
imagine: steel bolts are 50% heavier than titanium alloy bolts, so really that’s a massive saving. a full one third lighter!
weight is very important, especially when you got to carry it up the mountain before you can shred back down. every gram counts, and this is why we are going to replace all the steel bolts holding the brake rotor with titanium bolts.
there is one little rub: these bolts are tiny, m5 x 10 mm, so actually the set of six steel bolts required for one wheel weighs …. 12 grams.
hey, but that’s 4 grams of unsprung weight per wheel (!), which is sort of mildly important. that’s probably not quite a pee at the start of the ride.
but its titanium, that’s the coolest alloy out there. can’t argue with that.
