Re: Best easy glide for zero deg F ???

Decent glide on extra cold snow is a matter of ski (soft) and structure (very light). If you metal rotor brush back and forth you may rise some hair, which is bad. You'd rather rotor brush with different angles offset to remove hair. The best way to remove hair is a good scrapper. The hardest wax is...

Re: help -- how does biathlon get a pursuit aspect?

It's not true and it's very well thought. Think about classic + skate events : First day event : classic race Second day event : skate, in pursuit mode You can have three podiums : - Best classic skiers - Best overall skiers (obvious at the end of the second race - Best skate skiers. one can finish,...

Re: help -- how does biathlon get a pursuit aspect?

I understand it as two separate competitions, but they are as follow : Competition one : Sprint (One day event). Competition two : Sprint + Pursuit (Two days event). Biathlon is extremely well thought to balance skiing ability and shooting abilitiy. Some competitions tend to penalize poor skiing per...

Re: Skate ski camber and slipping on push off

Agree.
Plus, high camber ski are usually more stiff, meaning shorter contact areas and therefore more pressure at the contact areas. Providing a proper weight transfer and technique, they slip less than soft skis...

Re: Ptex -- tough vs waxable?

I think that Kuzmin says that stone grinds leave lots of hairs that must be dealt with : Either shaved or "glued" by wax. Also, he says that a stone grind can only produce short straight patterns, which is not necessary the best pattern. Maybe, maybe not. I think that a pure straight patte...

Re: Ptex -- tough vs waxable?

Hi, Since you're mentioning Kuzmin, he brought to our attention that there's no such thing of "waxability" didn't he ? No "pores" into sintered UHMWPE base. A very small amount of wax will "dilute" into amorphous parts of the p-Tex, once and forever... We're eagerly wai...

Re: Kuzmin scraping and structure

Good sharp tools for, say, wood machinery, are not cheap either. Also, At least for Kuzmin's or skimateria's, they are not producing a flat base and are not so "basic". The produced roughness is a very very important glide factor. So, producing a sharp and not straight tool is probably not...

Re: Kuzmin scraping and structure

Hi high speed roto-brushes is a brilliant idea IMHO. Note that the FP brush is another thing ; It is supposed to coat with a thin layer of Fluoropolymer, not polishing. I have no tested the new blades, but the new tungsten carbide one is promising, at least for the initial job of removing a layer of...

Re: Changing cleats on Salomon Carbon Skate Lab

This is great news. Much like bike shoes and cleats/pedals which can be selected independently. You won't change ski shoes cleats more than you change your bike shoes cleat, but at least and at last you can buy the bindings you want. I think It also opens a door for innovation in the bindings design.

Hi, I don't know how to gain access to the pictures. There's a video from Zach Caldwell http://www.caldwellsport.com/videos/ "flattening" There's also Kuzmin's and alike tools. To properly remove a "wave" (or not creating waves) you'd pull the scrapper with an horizontal angle. S...

Re: Hot waxing outdoors in Winter?

Hi If routinely ironing at 120°c your ski bases, which are likely to be between 10°c to 20°c at room temp, doesn't question you (100°c gradient !!), then bringing you skis outdoor for a quick work shouldn't... While the former will damage your skis for sure in the long run, the latter won't. Scrappi...
