Reeet got a new frame the other day an Adamant A1, great! My luck is that i ride it once and snap a maggie bolt in the thread, i have tried: -Making a groove for a flat head (no joy) -Drilling it out i.e. 3mm then turn it out No joy) -Heating the frame turning it out (no joy) my next plan is drill it out to M5/6 then tap it. my worries are will the tap be strong enough?? Or any other suggestions. BTW never buy these http://www.tartybikes.co.uk/product.php?id=10041 thanks Tom
