Has anyone ever seen chainring bolts that are a bit longer than usual, but not as long as those for double rings?
I keep stripping chainring bolts, on some old Miche cranks with thicker than usual spider tabs, and a thicker than usual chainring. As far as I can tell it’s a lack of thread contact that’s causing the stripping - I get them fairly tight and they just go ZING and spin around and around, going nowhere. When I eventually get them off again the first one or two threads are buggered and the rest haven’t been touched.
I got the bolts from Cheeky Transport, they’re no name ones but seemed ok. I think they’re plated steel, def not alloy. I’m using a decent tool to hold the back of them but that doesn’t help.
I’m tempted to completely swap ratios just to avoid the problem, but I think longer bolts would fix it. Anyone had the same problem?
