zoster Posted February 22, 2009 Report Share Posted February 22, 2009 hi..um... i got my marino frame, build up my bike (which btw feels incredibly good to ride, although i just tried it a bit), and on my first (and only) semi-ride, the rear wheel slipped on a sidehop and i hit the left chainstay on the ledge, and made quite a big dent (see pictures).my questions are:1. would this have happend on a more expensive steel frame (like curtis or lesson)2. would this have happend on an alu frame?3. what ca i do about it? i can hammer it back a bit? i can go weld some pieces of metal on that part, like the good boi frame has ... (i am really bummed, since this is a brand new frame and i was so excited about this bike it feels and look great, but...)4. is there the risk of this frame snapping on me?looking for some input..thanks!

Skoze Posted February 22, 2009 Report Share Posted February 22, 2009 Spoken to Marino?From my experience, all Leesons get dented on the chainstays, but nothing quite as bad as that! Speak to him, send him pics, see what he says? Quote Link to comment Share on other sites More sharing options...
Alex Dark Posted February 22, 2009 Report Share Posted February 22, 2009 if you hammer it back, the steel wont work harden half as much as aluminium would, so you should be fine on that count.....i think most frames would have dented on that, just depends on tubing thickness used really Quote Link to comment Share on other sites More sharing options...
Lewis-Trials Posted February 22, 2009 Report Share Posted February 22, 2009 That's not the worse dent, You will just have to keep your eye on it or get hold of the ammerdilo or however you spell it lol. Quote Link to comment Share on other sites More sharing options...

eskimo Posted February 22, 2009 Report Share Posted February 22, 2009 It looks like you didn't exactly land lightly either going by them deep scratches. To be fair it's low grade steel which didn't cost much. It would of done the same to an alloy frame. I really doubt that area is prone to breaking any more than previously. I'd leave it and alter your sidehop technique. And anyway, how did you hit the frame there on a sidehop? Is there no bb rise to clear that bit?And yes it would of happened to any other steel frame is that area wasn't designed to take hits.Thin tubing...

sstein Posted February 22, 2009 Report Share Posted February 22, 2009 Basically steel can be bent a lot without it loosing too much strength, whereas aluminium will break if it gets bent a lot. So hammering it back will not affect strength too much, but I don't really see how you can bend it back. If it is possible weld a small but stiff plate over it as you are likely to hit the same spot again, apart from that you should be fine.

N.Wood Posted February 22, 2009 Report Share Posted February 22, 2009 Personally I'd just leave it, if it cracks then reweld it, but for the moment I can't see much wrong with it. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted February 22, 2009 Report Share Posted February 22, 2009 In the meantime, throw up some pictures of the build. Been looking forward to seeing this complete Quote Link to comment Share on other sites More sharing options...
ogre Posted February 22, 2009 Report Share Posted February 22, 2009 cracks and dints at the rear end of the bike won't put you at risk as much as damage to the front of the frame, don't worry about it Quote Link to comment Share on other sites More sharing options...
zoster Posted February 22, 2009 Author Report Share Posted February 22, 2009 In the meantime, throw up some pictures of the build. Been looking forward to seeing this complete not quite yet, still waiting for a fork from ali c and a new saddle. i should have'em by Wednesday/Thursdaybut here's a preview if you insist:cracks and dints at the rear end of the bike won't put you at risk as much as damage to the front of the frame, don't worry about it thanks, i relaxed a bit now that i've seen the replies Quote Link to comment Share on other sites More sharing options...

forteh Posted February 22, 2009 Report Share Posted February 22, 2009 I would leave it, likely to only crack if its creased across the tube.Chances are it is a relatively thin tube compared to an aluminium one of the same size so more susceptable to denting, if it does crack then get it welded and stick a thin plate on there as armour plating - my triton frame has small bashplates welded on exactly where your dent is and Ive caught one of them on a wall, couple of scuffs but nothing else, because the plate is only welded top and bottom its not stressed and is unlikely to crack. The plate only needs to be 1-1.5mm thick to do its job Quote Link to comment Share on other sites More sharing options...

So hammering it back will not affect strength too much, but I don't really see how you can bend it back. If it is possible weld a small but stiff plate over it as you are likely to hit the same spot again, apart from that you should be fine. Lets be reasonable, welding a plate over it unless done by a highly qualified welder and being heat treated would be worse. At this grade of steel + thickness of the material probably wouldnt be alot more maluble than an alloy frame, so bending it back out, would only make things MUCH worse. Just get in touch with the manufacturer or leave it and zip tie a peice of curved carbon fibre or some hose pipe to the chainstay Quote Link to comment Share on other sites More sharing options...
forteh Posted February 22, 2009 Report Share Posted February 22, 2009 t-pro chainstay style then?Not sure, Im not familiar with the t-pro chainstays Looks like this.....(photo taken with bike upside down obviously ) Quote Link to comment Share on other sites More sharing options...
