i have looked around, to make my boxxer race perform better.
i know, i have 2 options to do this: blackbox kit and mojo boxxer kit.
so the question: which one is the better? or is better one of them than the other?
what exactly is inside of a mojo kit? (you could be more specific than "2 cl oil" or like this.) - pics, drawings, anything that can help me, is welcomed.

if this topic was here discussed, so pls post the link.

another question, not boxxer:
in a "horst-link" suspension design are the distances (or the angles, or both) of the bearings and the center of the rearhub's axle patented, or any frame, thet uses 4-bar linkage, where one of the bearings is at the chainstay (not kona-like at the seatstay) are "horst-link"?

thanks for help me.

nobody out there uses a mojo kit or a black box kit, or i'm just not right here, and must go to the downhill forum?

You'll get a better response posting in the DH forum.

Briefly:

The Mojo internals are a sealed cartridge damper unit (the Boxxer uses a ported damper), and I believe it is nitrogen charged. It's one sided so the other side just gets a little lubricating oil. Saves a bunch of weight, but the reviews of them are very mixed. Some people claim it's the best thing they've ever used, others hate it.

The "Blackbox" upgrade is a pretty simple upgrade, it's just more holes in a little aluminum plate to allow more oil to flow through.

And the Horst link covers a certain area in relation to the rear axle, and that area is specifically in front of and below the rear axle (it might not have to be below, but any Horst link I've ever seen has been). The link for a Horst link is on the chainstay instead of the seatstay. All the seatstay designs are "4-bar" designs (Specialized claims they aren't a real 4-bar but that's crap, they have 4 bars, so they're a 4 bar), but they aren't Horst links.
