1a2bcio8 Posted January 19, 2011 Report Share Posted January 19, 2011 Today we found 3 cracks in my drive side crank arm. I've decided to replace my current setup with some deity 3 piece cranks as new middleburns are stupidly expensive and I'm quite after a stiff setup. There's a slight problem to this however. There seem to be virtually no bash/chainring setups on offer for 3 piece cranks. On ebay I have found a "DMR ring thing elite" which will work (I used one years ago) but I won't be able to get it till next week after the bidding has ended - if I get it at all. That literally seems to be the only place they exist. To the bmxers out there; are there any 20 or 22t chainrings that permit a small bashguard? Or is there anything else out there at all? Help!

Scott Gibbs Posted January 19, 2011 Report Share Posted January 19, 2011 I think Macneill did a 23t bash/sprocket combo, im pretty sure infact. Have a look in RIDE magazine Quote Link to comment Share on other sites More sharing options...
Shaun H Posted January 20, 2011 Report Share Posted January 20, 2011 Today we found 3 cracks in my drive side crank arm... ...as new middleburns are stupidly expensive Don't Middleburn offer lifetime warranty? Although I don't know what their track record is with trials claims... Quote Link to comment Share on other sites More sharing options...
forteh Posted January 20, 2011 Report Share Posted January 20, 2011 Don't Middleburn offer lifetime warranty? Although I don't know what their track record is with trials claims... I think theyre pretty good with the RS7s, friend of mine had a set replaced after one snapped, I suppose on how ragged they are though.

Matthew62 Posted January 20, 2011 Report Share Posted January 20, 2011 There seems to be less than £20 differance between both cranks (arms only). The price of bash/ring is relative so i don't see where the huge price difference is? Quote Link to comment Share on other sites More sharing options...
1a2bcio8 Posted January 20, 2011 Author Report Share Posted January 20, 2011 The cracks were in a czar crank arm so there's no warranty there. To get new middleburns with either of the bashguards is about £160-190. I can get a stiffer setup for nearly half that it's just that I have to wait and bid on an item.

Luke Rainbird Posted January 20, 2011 Report Share Posted January 20, 2011 Ben - I used to run a Ring Thing Elite on my old Ashton ET. I'll have a little look around next time I'm at home as I can't remember if it's still kicking about at all, but if I've still got one laying about you can have it Quote Link to comment Share on other sites More sharing options...
Revolver Posted January 20, 2011 Report Share Posted January 20, 2011 (edited) I've got a set of charge cranks on my streety project and I use a 22t sprocket on there, with a 24t blackspire granny god bashring on the outside. If you turn the bashring round it hides the logos and text on it. Out of stock... Actually, the 4 hole one is out of stock, but the 5 hole one isn't. If you got a 5 arm spider on your cranks you could use the 22t, even better! Edited January 20, 2011 by Revolver Quote Link to comment Share on other sites More sharing options...
Mark W Posted January 20, 2011 Report Share Posted January 20, 2011 This is the Superstar one: Only down to 23t though. Couldn't find the 22t one, although I know one came out recently. Frustrating! But yeah, to run one of those and use your Rohloff you'll be needing to do some spacer tweaking to get a 1/8" chain through. Quote Link to comment Share on other sites More sharing options...
1a2bcio8 Posted January 20, 2011 Author Report Share Posted January 20, 2011 Thanks for everyones help. It seems I'm going to have to take the route of the dmr bash. Couldn't find a suitable spider for that potential. If you could have a look Luke that would be awesome. Hopefully I'll win this bid at the weekend for a new otherwise you might be my only chance.

quick_spider Posted January 20, 2011 Report Share Posted January 20, 2011 I can probably laser cut you one from 10mm steel - would just need figure out how to bolt on a standard 5 arm chainring (either tap threads in bash, or bolt all the way through. How do they locate on the cranks? Centre hole + one round key? Quote Link to comment Share on other sites More sharing options...

How do they locate on the cranks? Centre hole + one round key? Thanks Jon but I'm going to pursue the dmr bashguard route for now. What situation are you in where you can do that anyway? I thought you were on your way to lawyer land when we last spoke? Are you still riding at all? Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted January 20, 2011 Report Share Posted January 20, 2011 How do they locate on the cranks? Centre hole + one round key? Just for info it's the centre hole and one screw (which threads into a boss on the crank arm) which is usually around M8 (or silly imperial alternative for US cranks) in size.

JD™ Posted January 20, 2011 Report Share Posted January 20, 2011 Dunno how much it is for arms only for 'burns, but I have a black pro bash + 22t chainring than you can have for nowt (just a few quid for postage) if it makes a difference?

Not ridden for quite a while now - Think I last rode properly at a DJ ride Have been working in Manufacturing for the past 5 years, and I've got lots of fancy toys at my disposal including a laser cutter Jon Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted January 21, 2011 Report Share Posted January 21, 2011 I won't be able to get it till next week after the bidding has ended - if I get it at all. It's All Terrain who are selling them (http://www.allterraincycles.co.uk/) - give them a ring and offer them a tenner, I bet they'll bite your hands off Quote Link to comment Share on other sites More sharing options...
