Not worth it in the slightest, comparing the price vs weight loss will soon tell you that, as usual the first place to look is the tyres/tubes, followed by the wheels then contact points ie : saddle,seatpost,stem handlebars.
Ooooh, druidh….that’s a harsh blow straight outa the gate, we were going to wait till the thread ran to the 2nd page before we mentioned taking a file to the chunky welds on the frame
No, but I’m going to blow 250 quid replacing every bolt on my new bike with a Ti bolt. I weigh nothing and have zero body fat so I think I’ve earned the extravagance. It’ll shave less than the weight of a good dump off the bike but I’m still doing it for reasons I haven’t really figured out myself yet. If it makes you happy….

I’d look at where you are buying those bolts first andybloomer, chec out some of the online TI bolt motorsport specialists. I replaced every bolt i could on my Cove Hummer with titanium for way less than £100, i don’t care about the weight saving, or at least that wasn’t the primary objective – i just wanted to be a flash **** and once i replaced the rotor bolts i just thought fuk-it and replaced everything
Biggest weight saving for your £’s is aluminium bolts where they’re not under stress. Cheaper material, bigger weight saving.
You can get away with it on things like brake levers but probably not on your stem…
Do not ever, ever use Alu bolts on a stem! Not “probably” not on your stem- definitely not on your stem! Alu disc rotor bolts are dodgy ground too so 3x Alu and 3x Ti is the most you can safely get away with but is it really worth it over 6x Ti? I would suggest not but others may disagree. Using Alu bolts in anywhere except very select low stress applications will not end well!
Plus if you don’t install them with anti seize the threads gall and either they don’t tighten up enough or you cant undo them.
Had one for the main bolt in a Mk1 xlite seatpost. First ride was a nightmare as I couldn’t adjust it properly. Binned it and put an old steel bolt in. Never again!
From my point of view it’s not about the weight saving, it’s the mindset. What’s the point of having a dream bike if the last little bit of the jigsaw is a load of crappy steel bolts? If money was no issue, which in my case it’s not, no one would question it, they’d just replace the bolts and smile about the fact that they’d got a complete work of art, something to behold, is that not what it’s about?
If i were to replace my 12 rotor bolts with TI bolts, would i really save any weight or not?
To actually answer this question, if you’ve currently steel bolts of course you’ll save weight. I’ve replaced all my steel (except the stem) bolts with Ti, saves a bit of weight. But as was also pointed out you can run aluminium where they’re non-stress.
And irrelevent what others will say, you’ll climb hills easier with a lighter bike than a heavier one – although you may not notice…
