max-t Posted March 13, 2007 Report Share Posted March 13, 2007 (edited) Hi there buddy. I am testing the bashring and it is an 18 tooth bashring with a steel cog atactched on the inside by 9 steel bolts.The bashring is for use with middleburns but im sure you allready know of that if you looked on the site.There are only 2 of us that have these, (the other person being Mike singleton) and im not entirely sure wether steve would like me to send pictures around.Not to worry though as they will be available very soon from steve and will be no more than £40 for the bash ring and cog and bolts.Max...

I'd like to unveil these officially when the final product is available. They're being machined at the moment. Mike's been testing his bashring since the middle of Dec '06 and taken it around the UK to various rides where it's had alot of exposure and been ridden hard. Lots of positive feedback which is great Can't wait to reveal the full product features list and photos to illustrate. It could be in under a week now.

Luke Rainbird Posted March 13, 2007 Report Share Posted March 13, 2007 Can I just ask, why 9 bolts?Obviously you had as much choice as you wanted seeing as there's currently nowhere (to my knowledge anyway) that sells 18t chainrings, so you can set the standard, but do you not think that a simple 4/5 bolt configuration would have done the job just as well?Without seeing the design it's obvious that I can't form an opinion yet, as the bash could be multi-part, or something else that's a bit different from the norm, though I assume it's relatively normal, hence the 9-bolt question No chance of an initial idea/sketch perhaps?

To be able to fit the bolts inbetween the chain's new position (outer edge) and the recess for the lockring (inner edge) & these be strong enough, 4 things have to happen: Smaller PCD (diameter the bolts sit on).Smaller bolts.Sufficient thread area for strength compared to the usual configuration (remember the bolts are smaller now which affects this) taking into account a necessary increase in thread area due to the increased tangential force as a result of the PCD reduction (Torque = tangential force x radial distance).The new number of bolts has to be divisable into 18 exactly so that the bolt heads sit beneath sprocket teeth for max material around the hole.After working through this little challenge, I discovered the best mounting arrangement needed the 9 bolts, of the new size and thread length. Sorry there wasn't a quick answer! I hope you like the bash when I can reveal all Steve Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted March 13, 2007 Report Share Posted March 13, 2007 Sounds good - thought it may have something to do with that kind of thing.Thanks for taking the time to explain, I'm sure it will become clearer soon Quote Link to comment Share on other sites More sharing options...
