modifiedridah2k9 Posted July 19, 2010 Report Share Posted July 19, 2010 (edited) Hey guys. Okay one of my mates keeps arguing with me that bashplates will not crack the frame, or crack the bashplate mounts. So simple question, if you try bashguarding a wall, and hit it too hard a few times, will it crack the frame/mounts. Just to try and prove me wrong, he went and smacked his bike of the wall, and apparently nothing happened, He didn't check though, so yeah back to the question if hit to hard too many times will the bashplate crack either the mounts for the plate or your frame. EDIT: It even says on tarty, its to protect the chain, and if used wrong, is not covered under warrenty, It says something like that. Cheers, Kieran.

Cheers, Kieran. If you hit something hard enough, inevitably it's going to give. People do say that it can snap frames though Quote Link to comment Share on other sites More sharing options...
Alex Dark Posted July 19, 2010 Report Share Posted July 19, 2010 The weld where the bash mount is affixed to the downtube of the frame gives a massive stress raiser, a build up of force, along this very small area. This can cause frames to crack....and as is widely known aluminium will fatigue and snap under ANY load as long as it is applied enough times theoretically.

Laurence--Trials Posted July 19, 2010 Report Share Posted July 19, 2010 Search it on 'bike pictures' im sure theres some cracked GU's on there? Quote Link to comment Share on other sites More sharing options...
theom Posted July 21, 2010 Report Share Posted July 21, 2010 They sure do, Gu's are terrible for it for some reason. Quote Link to comment Share on other sites More sharing options...
Simpson Posted July 22, 2010 Report Share Posted July 22, 2010 BIU's just a dirtry disipline on the street, looks messy, sounds horrible and causes a lot of damage to walls, but companys are still designing street frames with bash's is wierd. Fine if its a learner bike, but if you know what your doing then there is no good reason to have one. Quote Link to comment Share on other sites More sharing options...
Jamie_Trials Posted July 22, 2010 Report Share Posted July 22, 2010 They sure do, Gu's are terrible for it for some reason. It's because they don't have gussets welded where the mounts are. Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted July 22, 2010 Report Share Posted July 22, 2010 Most Zona Zips crack at the bashplate mounts, but the actual mount itself, not the tubing. Get a grinder to it and a bashring, and you're good to go! Quote Link to comment Share on other sites More sharing options...
Jake Beach Posted July 22, 2010 Report Share Posted July 22, 2010 Ive hit my frame hard on the bash lots of times and my frame is showing no signs of weakening in that area Quote Link to comment Share on other sites More sharing options...
aener Posted July 22, 2010 Report Share Posted July 22, 2010 If you land on it hard, all of the force of your landing is put through those three relatively small areas, into the downtube/chainstays. The smaller the surface area a certain force is spread through, the more pressure it will exert. Edit: Meaning if the mount is on a large gusset which is welded to the downtube, it's less likely to crack than one with a small/no gusset. A frame won't crack just because it has the mounts - but it does dramatically increase the CHANCE of it cracking there. Quote Link to comment Share on other sites More sharing options...
Jake Beach Posted July 22, 2010 Report Share Posted July 22, 2010 How do you know? Have you had it X-Rayed? What I mean is you cant see stress makrs and stuff on it Quote Link to comment Share on other sites More sharing options...
TROYston Posted July 22, 2010 Report Share Posted July 22, 2010 They sure do, Gu's are terrible. Agreed. Quote Link to comment Share on other sites More sharing options...
t-comp-kierz Posted July 23, 2010 Report Share Posted July 23, 2010 It is less likely that your frame will crack if you have i think under the bash mount (as circled below) Quote Link to comment Share on other sites More sharing options...
Shaun H Posted July 23, 2010 Report Share Posted July 23, 2010 The old polished T-Mags were terrible for it as they did not feature a gusset like the one pictured above (clearly Onza learnt from that mistake!). I think it's more of a question of bad design. A bashplate is there specifically to be bashed instead of the frame, it wouldn't be doing much good if it still caused the frame to break! If well designed the bashplate should prolong the life of the frame; even if when the frame finally fails it's at the bashplate mounts, the main point of including one is to extend the frame's life.
