Ezg_Cannuck Posted December 4, 2008 Report Share Posted December 4, 2008 (edited) Hey guys,I was just wondering if it's possible to: 1) find a bash plate with geometry designed for a stock bike 2) if such a thing exists, but my bike doesn't have mounts for a bash plate, is it possible to custom fab?You see, I'm worried about denting/cracking my frame on the down tube when I miss...as i'm a heavier rider. Any help would be great.Cheers Edited December 4, 2008 by Ezg_Cannuck Quote Link to comment Share on other sites More sharing options...
Ben John-Hynes Posted December 4, 2008 Report Share Posted December 4, 2008 Not sure about being able to fabricate one and mounts too. But I know the old onza T-Rexs had them. Quote Link to comment Share on other sites More sharing options...
Gandalf the Yellow Posted December 4, 2008 Report Share Posted December 4, 2008 Base TA26's..what is the point though, most riders nowadays ride with as little bashing as possible...i mean look at the size of the bashrings nowadays, they're bloody tiny!!steve Quote Link to comment Share on other sites More sharing options...
psycholist Posted December 4, 2008 Report Share Posted December 4, 2008 If your frame doesn't have mounts for a bashguard there is still the option of making a custom guard with aluminium grip plate and a few jubilee clips... Trials frames are designed to take the odd knock on the downtube anyway, so unless you routinely hit the downtube or want to keep your frame pristine you're pretty unlikely to break the frame doing this...

NVWOCI WVS Posted December 4, 2008 Report Share Posted December 4, 2008 I designed a type of skiplate that doesnt need mounts on the frame. Probably wouldnt work though... Quote Link to comment Share on other sites More sharing options...

shamus Posted December 5, 2008 Report Share Posted December 5, 2008 Like Ben originally said old Trex. I have an old t-rex frame with bash plate mounts. unfortunately i lent it out for a bit and they managed to damage the bb threads so you coulds have it for 20 quid? its quite short which is lovely for streety trials but i dunno. if your interested PM mesome frames have plates on the downtube to prevent dents etc my monty (stock) had a plate covering the lower 2/3rds or 1/2 of downtube which was pretty goodunless your tryin rails or really pointy natty chances are you wont catch your down tube very often anyway Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted December 5, 2008 Report Share Posted December 5, 2008 The only stock frames I know that had them are:The old Saracen MADs - 2003/4?T-Rex.Base BA26.I don't see the need for a bashplate, when you can just have a bashring on one half of the cog.

forteh Posted December 5, 2008 Report Share Posted December 5, 2008 A cheap downtube protector can be manufactured from a section of old tyre with the wire bead cut out and some thin aluminium sheet (1-2mm thick should be sufficient). Position the length of tyre on the underside of the downtube, overwrap it with the aluminium and clamp it all up solid with jubilee clips. Should stop the majority of dents but not weigh excessive amounts - when the aluminium gets ragged just replace it and jobs a good un Quote Link to comment Share on other sites More sharing options...
Ezg_Cannuck Posted December 5, 2008 Author Report Share Posted December 5, 2008 Cheers for the advice from everyone. Now just out of curiosity, does anyone think it would be possible to drill holes and tap them so a plate could be mounted? ...hypotheticallyA cheap downtube protector can be manufactured from a section of old tyre with the wire bead cut out and some thin aluminium sheet (1-2mm thick should be sufficient).

psycholist Posted December 5, 2008 Report Share Posted December 5, 2008 B&Q would be one option, but if there's an engineering works near you you'll probably get it cheaper than B&Q (And possibly cut to size for you) if they have suitable sheets in stock...

Alex Dark Posted December 8, 2008 Report Share Posted December 8, 2008 dont do it....used a bashplate on a astokc and its rubbish...too much weight hanging off the bottom of the ike...and it gets in the way Quote Link to comment Share on other sites More sharing options...

Now just out of curiosity, does anyone think it would be possible to drill holes and tap them so a plate could be mounted? ...hypotheticallyYou'd remove far too much strength from the downtube. At the end of the day it'd do more harm than good. Quote Link to comment Share on other sites More sharing options...
psycholist Posted December 8, 2008 Report Share Posted December 8, 2008 The BB shell or possibly chainstays would be the only places where the frame might be thick enough to take enough screw threads to hold a bash guard firmly. Putting a hole in a plate under tension roughly triples the peak stress (If I remember my stress concentration factors correctly) in the part even if the screw hole doesn't significantly change the area of material supporting the load. Jubilee clips are the way to go as these don't require you to modify the frame at all... Who'd have thought that this was a valid website: http://www.jubileeclips.co.uk/ Quote Link to comment Share on other sites More sharing options...
