Welcome to the new and improved Proflex / K2 Tech Forum!
Hmm sealed bearings on the 856. Good idea.
Simon - Do you think the conversion would change the ride of an 856? Did you weigh the parts that you used for your 4500? I am a weight weenie so I would be interested in what the net gain/loss in weight would be with the conversion. Trevor [smiley=beer.gif] [smiley=beer.gif] [smiley=beer.gif]
