Misfit Psycles (the Corporation) does not subscribe to 'Model Years' as many other, less personable, companies do.
Instead, Misfit Psycles (the kinder, gentler Empire) elects to produce products in smaller, more intimate batches.  This allows for subtle improvements and variances to be applied as frequently or infrequently as necessary.

While this ensures that the Psycle Products are never restricted in their quest for 'awesome' it can, on occasion, make tracking or identifying a particular 'batch' difficult.

The majority of products aside, frames are the product most likely to benefit from small batches, most likely to see small variations and most important to track.

The diSSent (Al) is a good example.

Since it's inception and introduction the diSSent has seen 2 slider systems (as of October 29, 2009). 

CNC (black) and FORGED (silver). 

CNC (black)

The CNC (black) version was the original and majority slider that has been sold with the diSSent (Al) frame.  It is currently the STANDARD slider for the diSSent (Al).
Word on the street (that has been verified and the like) suggests that the Misfit Psycles slider system works with MANY other slider systems from several other manufacturers.

Advantages:
Black
CNC'd.  This provides a perfectly flat (Disc Brake) caliper mounting surface

Disadvantages:
Not Silver


FORGED (silver)

The FORGED (silver) version was provided on batches of frames beginning with the Mk.ii dropout design (clarification of which is which and which way is up, HERE).
There is not a soul alive that could explain the appearance of the FORGED (silver) system.  It simply appeared one day.  Never requested, never explained.
Silver DID look nice on occasion and all but offered NO IMPROVEMENT over the initial CNC (black) slider whatsoever.
Word on the street is similar with these FORGED (silver) sliders, they also work with some of the slider systems produced by other manufacturers.

Advantages:
Silver for a change

Disadvantages:
Forged.  Not entirely a disadvantage on it's own.  Forged sliders can be rounded at the edges (presumably for aesthetics).  This rounding of the forged sliders required marginally greater TLC when installing hydraulic brakes...that is when installing 5 sets a day.  Average users will NOT see this as a major inconvenience.

There is NO NEED to upgrade or swap or otherwise change your FORGED (silver) sliders for CNC (black) sliders...unless you really want to.

HARDWARE

Unintentionally and by accident many of the frames with FORGED (silver) sliders were shipped with 5mm head allen bolts.  While not entirely defective, the smaller head was prone to stripping.
Strong and powerful 6mm head allen bolts are the STANDARD and were provided with ALL CNC (black) sliders.  They were also provided as EXTRAS to those customers that requested FORGED (silver) sliders.

There is not danger (aside from inconvenience) associated with the use of 5mm head allen bolts. 
But given the choice, why use them?

Managed to out-muscle the 6mm heads? 
You suck, however, that won't stop you from purchasing a replacement set HERE.



This discussion pertains to SILDERS only.
There have been revisions to the dropouts as well.  Dropouts are discussed HERE.
