TheFabricator Posted March 26, 2006 Report Share Posted March 26, 2006 My lad has a Monty Magura and practises on pallets.If he climbs on and rests on the chain it bends the rear axle every time. Is there a block or something available to fit between the chain and stay. if not im going to weld one on the the back of the bash guard or something to try and stop it. what do you seasond lads do.

Ash-Kennard Posted March 26, 2006 Report Share Posted March 26, 2006 sorry I don't understand.try and get some pictures up Quote Link to comment Share on other sites More sharing options...
Endohopper Posted March 26, 2006 Report Share Posted March 26, 2006 Hmmm, not exactly sure what you mean here ... You're actually bending axles regularly ? sounds like the wheel simply isn't tightened enough , allowing it to move when pressured ie by the chain , without causing any damage to the axle itself .

cvtrial Posted March 26, 2006 Report Share Posted March 26, 2006 Can you take a pic of this crazy stuff? I do not understand eigther! Quote Link to comment Share on other sites More sharing options...
TheFabricator Posted March 26, 2006 Author Report Share Posted March 26, 2006 that was fast thanks for your replies.it is the increase in chain tension caused by landing on the chain which pulls hard on the sprocket and bends the axle. the axle cant pull forward as its tight and held by a cam against a stop bolt in the frame.so it bends.its the section of chain between the tyre and the bash plate wich is vunerable.

Lawnmowerman Posted March 26, 2006 Report Share Posted March 26, 2006 How big is the gap between the chain and the chainstay? If it's massive try putting something between them to act as a stop Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted March 26, 2006 Report Share Posted March 26, 2006 So.. the wheel's tight, and when he bashes, the wheel slips in the dropouts? I guess you could try wedging something in the dropouts, weld it in or something, like you said. You can get washers with a sort of 'grip' on them too, you could perhaps out thopse on the axle, inbetween the wheel nut, and dropout. Hope I've understood you correctly, and you'll understand me correctly. Quote Link to comment Share on other sites More sharing options...
dave85 Posted March 26, 2006 Report Share Posted March 26, 2006 Something like that should sort you out. Quote Link to comment Share on other sites More sharing options...
TheFabricator Posted March 26, 2006 Author Report Share Posted March 26, 2006 Thanks dave that looks like what i need.I assume yours is welded to the frame as you have no bash plate.Im going to weld one on the back of the bash plate or maybe a bracket holding a nilon block like the moto x lads use as chain guides.

Jsy Ben Posted March 26, 2006 Report Share Posted March 26, 2006 ah confusing stuff !! so your not bending wheel axles , your bending bottom bracket axles ?! Quote Link to comment Share on other sites More sharing options...
dave85 Posted March 26, 2006 Report Share Posted March 26, 2006 Nylon block is the ticket, its quieter than a chunk of metal. I had one with a few holes drilled through it from side to side and then cable ties holding it to the stay. Not overly secure but it worked well.

ogre Posted March 26, 2006 Report Share Posted March 26, 2006 you could move your wheel in a bit so the chaind can move round a bit more... Quote Link to comment Share on other sites More sharing options...
dave85 Posted March 26, 2006 Report Share Posted March 26, 2006 So it'll flap around like a wizard's sleeve, yeah proper good idea that one. You just keep excelling yourself. Quote Link to comment Share on other sites More sharing options...
