October 26, 201213 yr Well this is a racking frame! In more ways than one. When rebuilding my bike earlier. I noticed a crack, then another, then looked round the other side of the frame and there were another two. Here's a few pics I took... Fair enough it has probably taken a fair battering from me but I am not Albert cabestany over here. Has this sort of thing happened to anyone else? It is a 2010 bike/frame? I recall sherco being quite good with frame replacements or is that me getting it mixed up with a push bike company? If not can I weld it up easily? I.e is it not some funky alloy that needs special treatment? Cheers for any help
October 26, 201213 yr Its prolly chome moly (CrMo)... My guess would be use a similar high tensle wire such as 80SB2. I suggest using A15 or A18 wire or an 80. TIG weld it.
October 26, 201213 yr But of course you would have to cut the cracks out or at least thin them out first before we-welding
October 26, 201213 yr no. drill a small hole at the end of the crack to stop it creeping. then grind a V along the length of the crack. then weld it.
October 27, 201213 yr Yea, that bike is well ridden! Doubt you will find much warranty but it would take me little time with a disk grinder and the MIG to toutch that up! Nothing special about the CrMo really, although you will get other opinions. The welder himself being more important than the method used. If you have a good TIG man nearby, use him, your call.
October 27, 201213 yr That looks, to me, to be a classic case of an engineering business that does not believe in finite element analysis when designing a new fabrication (frame). We're not just looking at a few poorly penetrating lug welds, the stresses in that frame have not been accounted for. IMHO
October 27, 201213 yr Buy a Beta . Yeah, their frames never crack? :rotfl: Your reply is so unhelpful, your TC name should be FatuousB45t4rd

October 27, 201213 yr If a Beta frame cracked I'd think it would be tricky repair compared with the Sherco. These bikes are built to be light so no way can a maker build something that will stand repeated heavy use. Some riders would break an anvil so I wouldn't be pointing any fingers at particular makes.
October 27, 201213 yr I was just winding them up didnt think anyone would bite. I've had Gas Gas frames crack , just routed it and welded it up never had any problems with it again. I'm think manufacturers build bikes for weight not longevity , trying to get you to upgrade every year. Edited October 27, 201213 yr by fatbastard

October 27, 201213 yr Hi´ all Sherco did replace a frame for us here in Denmark. It cracked near the footrests and near the headstock. All the best Christian
