here), and I wanted to expand and clarify a couple of points.
First off, I love the basic reliability of a good horizontal drop out/track end. The one seen here is from the Origin 8 Scout, and as you can see, it has a built in tensioner. I do not expect it to shift, creak, or be an issue while riding. The issue with these comes up when you have to remove the rear wheel. That is where I have a big problem with this sort of system, and I outlined most of that in the other post. One final thing I wanted to add was in regards to "usable axle placements"
Most companies will tell you the shortest axle setting is smack dab against the front of the horizontal drop, (ie: all the way forward). In reality, this is a very difficult place to tension your chain to. (This isn't even touching getting the wheel out). In reality, you probably are not going to get that axle smacked up against the front of the drop out and achieve the "shortest chain stay" measurement. I know a lot of companies don't list the chain stay measurement this way, but many do. Also, you will find that many times the chain stay clearance will not allow a fatter tire that far forward. I'd like to see companies list chain stay length specifying a certain width tire and give "real world" chain stay adjustment measurements. C'mon company guys! Do this. Shoot straight with us. (This goes for sliding drop out bikes as well)
My good buddy MG commented yesterday on Salsa Cycles new swinging drop out as seen on the new Ala Carte and El Mariachi frames. I have not "lived with" one of these set ups yet, so I didn't put it on my "favorites list", but judging from my limited test ride and my looking into this closely, I think it may rise to the top of the heap alongside the split shell EBB.
You have vertical drop out simplicity, alignment issues solved, and as long as the swing is putting a real world tire, (2.0-2.4"), in usable space in the chain stays throughout its travel, I will sign on as a endorser of this system.
As for EBB's, I have used Phil Wood, Bushnell, and split shell types, but I haven't had any issues with noise or anything at all but nice quiet operation. I know the "haters" of EBB's will denounce any mention of these systems as being good, but hey......they are. At least for me!
Finally, I think sliders "could be" done well. I have seen newer takes on sliders, (not Paragon), that seem to have promise, but again- without "real world" time on these, I can not say. Too many times I see Paragon type sliders welded on unevenly, and also with usable axle placement that conflicts with the chain stay clearances. One slider system that I have never had issue with, that I thought was something I could have lived with, was on the Misfit Psycles diSSent frame. Those had usable range that did not conflict with clearances and were reliable, simple to set, and could be trusted not to slip.
Okay folks, that's all I have on this subject today. Ride that single speed, or whatever bike you own, and have a great weekend!!
