Comments on: Dynafit Addresses Boot Pivot Wear — Almost Enough

I guess that the problem should be less serious with the green machine than with the TLT 5 P. Never owned a green machine, but as it looks on photos the cuff rivet seems to be better made. Further the rivet does not run only trough a hole in carbon (as it is the case with the carbon cuff of the TLT 5), but through carbon (powerstringer) AND pebax (the actual cuff of the green machine).
I owned a Dynafit Zzero px for lets say 150 to 200 days of touring and it never developed a problem with pivot wear.

@grosenkranz: The first time I really noticed the problem on my Green Machines of similar age and use to yours was when one of the cuff rivets sheared at the end of a mellow sidecountry run this New Years Day. My theory is that the increased cuff play put increased shear and bending forces on the rivet, which eventually broke. I got that rivet replaced by a screw-washer-nut combo that works, but after that I lost my trust in those boots for long/remote tours because of the uncertainty over the other three rivets.

I’m trying to understand if this is a problem with my boots–Dynafit Green Machines from 2011. The cuff has just a bit of play after 100+ days (about 30% at resort) over two seasons. I don’t think I notice it at all when skiing or skinning now but I suppose it will get worse?

@ Besniwood:I also do not understand why Dynafit does not install that metal reinforced rivets in every tlt. Weight should be not the reason, as the fibre glass Version (metal reinforced) will only weigh 35 g more than the carbon one. Maybe the reason is that they have still many of the old cuff rivets left in the factory as Lou assumed already further above.
In fact the metal reinforced solution must exist for some time now, as their is at least one shop who says that they would test the tlt 6 cc for several month now already.
That TLT 6 CC will be a very limited Version I assume, as there are only few Shops in Europe that will offer it and one should order it right now to get the shoe in fall…
Another thing I do not understand is why they make the TLT 6 wider than the TLT 5. TLT 5 is a dream for People with narrow feet, but almost everyone with normal feet I know loves the fit also and thinks that the narrow fit enhances the Performance. At least Dynafit could be the first Company to offer the same boot in a “narrow” and a “normal” fit, as the molds for the tlt 5 (narrow) already exist. I think they would really sell more boots by that.

I just heard back from Salewa about the delrin bushing in the Vulcans. They contacted the boot developer in Italy (Giovanni?) to check and told me that both the 2012/13 and 2013/14 models have the delrin bushing in the cuff rivet.

Those metal reinforced cuff rivets in the TLT 6 CC sound good. I wonder why Dynafit won’t include them in the whole line? Weight saving?
