Mark W Posted September 4, 2006 Report Share Posted September 4, 2006 If they're eccentric you get the advantages of being able to slightly tweak the tension to a limited amount, shear the bolts and bugger your frame up, have your wheel slip round, and stuff like that.It's all pretty good Love you really Mike Quote Link to comment Share on other sites More sharing options...
Phatmike Posted September 4, 2006 Report Share Posted September 4, 2006 What advantages would that have over horizontal dropouts though?As mark said, they're eccentric, ie the axle is placed off axis, so it can be rotated to tension the chain. Meaning there isn't a need for a chain tensioner. A removable mech hanger will be placed on the chainstays for comps. Quote Link to comment Share on other sites More sharing options...
JT! Posted September 4, 2006 Author Report Share Posted September 4, 2006 (edited) Yeah, i know who they work, to some extent.But why create something new when horizonal dropouts work just fine. Edited September 4, 2006 by JT! Quote Link to comment Share on other sites More sharing options...
Todge Posted September 4, 2006 Report Share Posted September 4, 2006 Yeah, i know who they work, to some extent.But why create something new when horizonal dropouts work just fine. To push the limits of what is possible? You never know, could become the standard one day They may well not work at all, but from first impressions, they do hold suprisingly tight.We'll have to see Quote Link to comment Share on other sites More sharing options...
Mark W Posted September 4, 2006 Report Share Posted September 4, 2006 First impressions from what, if you don't mind me asking? Mike showed me a pic of his frame in the jig, and I don't really get how you could get much force through it as is? I'm not trying to be a dick or whatever, but I was just wondering It's cool it's being tried out though, like you said it might actually work Quote Link to comment Share on other sites More sharing options...
ScotchDave Posted September 4, 2006 Report Share Posted September 4, 2006 You know what, why don't we just get adjustable chainstays and hinged seatstays, that'd be strong and simple... Quote Link to comment Share on other sites More sharing options...
Phatmike Posted September 9, 2006 Report Share Posted September 9, 2006 Update:Eccentric dropouts for the f**king w!n They work an absolute treat, I get a lot more than a full chain link's movement, and best of all, no mech! (Have a bolt on gear hanger too, for those dirty comps )I'm extatic. Quote Link to comment Share on other sites More sharing options...
JT! Posted September 9, 2006 Author Report Share Posted September 9, 2006 I'm extatic. So how do you tension the chain. Because there's no kind of leaver to grab and turn it round is there? Quote Link to comment Share on other sites More sharing options...
Phatmike Posted September 9, 2006 Report Share Posted September 9, 2006 You can tighten the hub bolts, (sort of hard to explain), and then use the allen key in the hub bolts to rotate it all. It's really easy to adjust the tension. Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted September 9, 2006 Report Share Posted September 9, 2006 Nice design Mike.So you have to depend on that clamp to hold the wheel in place?Does it work well, or would/does it slip?Not having a dig..just wondering. Quote Link to comment Share on other sites More sharing options...
Gazza Posted September 9, 2006 Report Share Posted September 9, 2006 That 360 dropout will not slip. This kind of holder is widely used in machines of all kinds. Just take the old-style stems and bars. They used to have one bolt. And you could hardly slip the bars around. And the power aligned to the dropouts is different and does not apply on slipping the excentrics. Quote Link to comment Share on other sites More sharing options...
paolo Posted September 9, 2006 Report Share Posted September 9, 2006 I'd have to go with horz, having used some their'e seriously way less trouble than verticals, just get a real bolt-on axle and your on your way. Thought I don't know how well horizontal drop-outs work with maggies. Another entersting desing for frames with bmx sized bb and vert drop-outs (not that there are alot trials frames with bmx bbs...) is an eccentric adaptor to regular bb size...

Sam Nichols Posted September 9, 2006 Report Share Posted September 9, 2006 From my experience horizontal is the way to go.Basically my set up is hope trials hub, revell frame and an avid ultimate.I put it all together tightened it all up, got the tension perfect with chain tugs and that's it. I haven't touched it. I run maxxis tyres so I don't need to worry about punctures, but they wouldn't be too much hassle really.My wheel NEVER moves, my tension is always perfect. I can't see why you would want vertical drop-outs.Take a look.The above is an old pic from when I had a king with a quick release (that didn't work too well!).But just look how tidy it is. I think it's the best way forward personally. Quote Link to comment Share on other sites More sharing options...
