Behind the Numbers: Specialized Stumpjumper EVO 29 Suspension Analysis
@Mondbiker: Except they don't absorb side loads. I will say that any rolling element bearing is going to be less likely to bind, but that's it. A spherical bearing allows significantly more angular misalignment than a standard bearing or bushing, but they transmit axial load and radial load. As such, I don't see how they could "absorb" side load. They would merely pass it on to the supporting components. There are spherical bearings of many varieties, roller and plain. There are many types of self aligning bearings too, which don't necessarily have to be spherical bearings. If the way to reduce side loads on the shock is to provide a larger degree of angular freedom, then self aligning bearings are the solution. The same problem could also be solved by making the rear linkage stiffer. I am not a frame designer and do not know which would be better, but there are multiple ways to solve the problem of side loading shocks, and I suspect that spherical roller bearings are not the right option. This isn't to say that using self aligning bearings in the appropriate places isn't a good thing, or using ball or roller bearings instead of plain bearings won't result in lower friction, because it will. However, I think it is important to be clear about which components we are talking about, what they do, and how changing them will improve the bike and the reason for and against the changes.

Dan Atherton Unveils Prototype 22" Titanium BMX
@vinay: Anyone who does pedal or crank grinds on a unicycle isn't using a disc brake. Even in trials riding nobody runs brakes, and it would benefit the most out of all the urban disciplines.

All the Adjustments: Formula Introduces the Selva R Fork
@Socket: So its like a tender or a helper spring on a wrc car, except the main spring is progressive? Which seems like it could lead to some pretty interesting looking spring curves, instead of the standard inverse relationship of an air spring. If you have any graphs showing its behavior, I would be interested to see them.

@Socket: Isn't the neopos made out of a different material from other volume spacers, so it would have a different modulus of elasticity, which would change the spring curve by some amount? Not saying if its good or bad because I haven't tested it, but it would still be different.
