ogre Posted November 13, 2012 Report Share Posted November 13, 2012 hey tf, i acquired a 20" a few months ago, the front end has some alloy bolts in the stem and mounting my disc brake. i've started doing moves to front, i'm not the slightest of people, and i like my teeth. are alloy bolts up to the job? whats the life expectancy of them? or are they mint and better than i give them credit for and i should stop worrying and enjoy the purple lightness?

narrowbars Posted November 13, 2012 Report Share Posted November 13, 2012 You 100% sure there alloy bolts, could quite likely be titanium? Generally alloy bolts in any load bearing area is a bad idea on a trials bike. If there titanium they'll be fine (make sure there greased or copper slipped) but if there alloy i'd personally change them back to steel or titanium depending on budget. I run titanium bolts in load bearing area's and alloy in non load bearing area's. Quote Link to comment Share on other sites More sharing options...
Jake. Posted November 13, 2012 Report Share Posted November 13, 2012 Paul, it would be awesome if you could name some of the load bearing areas? So I know I haven't missed any, I fancy getting some of those anodized alloy bolts. Quote Link to comment Share on other sites More sharing options...
ogre Posted November 13, 2012 Author Report Share Posted November 13, 2012 they're definatley alloy (they're purple) could i run half an half with ti and alloy? or do i want all ti? i wouldn't want alloy bolts holding my brakes, wheels or bars in place. so crank bolts, steerer clamp, star nut bolts, pedal bolts, bottle cage mounts tensioner (if you got a sprung one...) they havent failed yet, but they're holding my disc caliper to the forks, and i don't wanna sheer through them Quote Link to comment Share on other sites More sharing options...

And nothing happened. Quote Link to comment Share on other sites More sharing options...

It's still like that and nothing has self destructed, yet! But they were tightened with care... Quote Link to comment Share on other sites More sharing options...
N.Wood Posted November 14, 2012 Report Share Posted November 14, 2012 I have run pretty cheap quality alu bolts on what I'd say are pretty high load areas (front axle bolts with disk brake) before and they have snapped the head off them after like 8 months of hard use. I run Ti stem bolts and they have been fine so far. I use an alu bolt for my topcap bolt and its been great for 3+ years. Even when the bolt snapped (both times) nothing really happened was just a loud bang and my wheel went a little wobbly. Quote Link to comment Share on other sites More sharing options...
J.KYDD Posted November 14, 2012 Report Share Posted November 14, 2012 I'd run ti for axles, disc rotors, bars/stem + 4-bolt mounts. I run alloy bolts on my Magure lever and top-cap Quote Link to comment Share on other sites More sharing options...
nztrials Posted November 21, 2012 Report Share Posted November 21, 2012 I have run alloy bolts almost everywhere on my bike for some time now, the others are titanium and i run these on the hub bolts, disc brake mounts and the stem where it clamps onto the bars. Ive only had two bolts fail and these were both when unscrewing them, both caused by not using antiseize Quote Link to comment Share on other sites More sharing options...
