Apparently this is much stiffer, however I have not ridden the older version.

 I'm riding it with the 135mm for now, until I replace my back wheel.

 Nice Tracer 2. I have the 142 x 12 on mine. Waaaay stiffer than the 6.6...

 Thanks mate, I've not tried the 142 yet because I had a set of wheels to go on this build already.
Still unsure whether I would swap to 142 though as I don't quite understand the point of it.

Have you noticed any real world performance gain?

 yea its a 12mm thew axle.. and is set up like a maxle one of the dropouts are threaded. the hub spacing is wider because the dropouts get slotted for the hub to rest on..

 I'm waiting on the new DH bike, this is just the "other" bike. Like a skelmpie - lekker om te ry wanner die vrou nie kyk nie!

 Ja bru I know what you mean. So you getting the new Morewood, with Bos?

 Yeap, I'm just waiting on the 2012 BOS stuff to come in stock
